Characterization of Nano Calcium Carbonate Extracted from Eggshells

Organic waste, especially eggshells, represents a valuable resource for the synthesis of calcium carbonate nanoparticles, which have significant industrial and medical applications. This study describes the methodology for converting eggshells into calcium carbonate nanoparticles through heat treatment and nano milling processes. Advanced characterization techniques, including TEM, SEM, and AFM, were used to analyze the morphology and structure of the synthesized nanoparticles. The particles were found to be of nanometer dimensions, with a size of around 150 nm and a distinctive spherical shape, as shown in the TEM images. SEM images showed that the surface of calcium carbonate nanoparticles synthesized from eggshells is smooth, crystalline, and spherical or nearly spherical. FTIR analysis revealed the presence of distinct functional groups for calcium carbonate, with peaks at 713–868 cm⁻¹, consistent with previous studies. The results show that nanoparticles manufactured from calcium carbonate possess unique properties that enhance their applicability in various fields, and promote sustainability and environmental preservation.

Fabrication of a natural nanocomposite from Syzygium cumini and squid bone waste decorated with Cu-Nps for simultaneous use in the triple method of photodynamic/photothermal/chemotherapy.

This work reports a new nano platform made from natural materials. For this purpose, calcium carbonate nanoparticles derived from Persian Gulf squid bones as a drug carrier, Syzygium cumini (dye extracted from the fruit of the Persian Gulf trees) as a photosensitizer, and Doxorubicin as a chemotherapy drug have been used. In addition, copper nanoparticles were added to the above composition to increase the efficiency of photothermal treatment. For phototherapy, samples were irradiated by an 808 nm laser (1 W). The results show that nanocomposites play an influential role in the reactive oxygen species process, and an increase of 21 degrees in temperature during 15 minutes of laser radiation is effective in photodynamic/photothermal therapy. The drug loading capacity of the nanocomposite was calculated as 49%. This new nanocomposite for simultaneous photodynamic/photothermal/chemotherapy holds great promise for future cancer treatment due to its excellent potential in treatment and reduced systemic toxicity.&#xD.

Improving the Productivity and Physiological Characteristics of Lettuce Plants Using Spraying Calcium as a Nanofertilizer

Implementing nanofertilizers in cultivation to enhance food security is important and gaining great significance, as they have good properties to improve plant production, phytochemicals, and nutrient efficiency and thereby meet the demands of the increasing world population for food. This work demonstrated the impact of calcium carbonate nanoparticles (Ca-NPs) and Ca bulk at three concentrations (0, 100, and 200 mg L−1) on growth, productivity, photosynthetic pigments, phytochemical content, antioxidant activity enzymes, minerals, toxicity, and genomic DNA of lettuce plants. In this regard, Ca-NPs at a concentration of 200 mg L−1 reinforced the vegetative growth characteristics of lettuce plants, increasing head length by 15.7 and 19.2%, head diameter by 20.3 and 19.9%, head fresh weight by 54.4 and 52.9%, and production per hectare by 54.7 and 52.8% as compared to the control during the two growing seasons. Furthermore, the percentages of total chlorophyll (62.6 and 59.5%), carotenoids (48.4 and 56.5%), total phenolics (63.6 and 65.7%), total indoles (39.4 and 36.4%), vitamin C (39.7 and 39.6%), antioxidant activity (57.8 and 53.7%), nitrogen (70.5 and 67.5%), phosphorus (120 and 110.5%), potassium (33.0 and 33.2%), and calcium (67.14 and 63.2%) were also increased compared with the control during two consecutive growing seasons. Additionally, Ca-NPs and Ca bulk had an impact on the plants’ genomic DNA compared to the control. In addition, lettuce plants treated with Ca-NPs were proven to be nontoxic and safe for humans by using the Microtox 500 analyzer.

Targeted Delivery of Celastrol by GA-Modified Liposomal Calcium Carbonate Nanoparticles to Enhance Antitumor Efficacy Against Breast Cancer

Background/Objectives: Breast cancer, a leading health threat affecting millions worldwide, requires effective therapeutic interventions. Celastrol (CEL), despite its antitumor potential, is limited by poor solubility and stability. This study aimed to enhance CEL’s efficacy by encapsulating it within glycyrrhizic acid (GA)-modified lipid calcium carbonate (LCC) nanoparticles for targeted breast cancer therapy. Methods: The 4T1 mouse breast cancer cells were used for the study. GA-LCC-CEL nanoparticles were prepared using a gas diffusion method and a thin-film dispersion method. GA-LCC-CEL were characterized using the zeta-potential, dynamic light scattering and transmission electron microscope (TEM). The in vitro release behavior of nanoparticles was assessed using the in vitro dialysis diffusion method. Cellular uptake was examined using flow cytometry and confocal microscopy. Intracellular ROS and Rhodamine 123 levels were observed under fluorescence microscopy. MTT and colony formation assays assessed cytotoxicity and proliferation, and apoptosis was analyzed by Annexin V-FITC/PI staining. Wound healing and transwell assays evaluated migration, and Western blotting confirmed protein expression changes related to apoptosis and migration. Results: GA-LCC-CEL nanoparticles displayed a well-defined core-shell structure with a uniform size distribution. They showed enhanced anti-proliferative and pro-apoptotic effects against 4T1 cells and significantly reduced breast cancer cell invasion and migration. Additionally, GA-LCC-CEL modulated epithelial-mesenchymal transition (EMT) protein expression, downregulating Snail and ZEB1, and upregulating E-cadherin. Conclusions: GA-LCC-CEL nanoparticles represent a promising targeted drug delivery approach for breast cancer, enhancing CEL’s antitumor efficacy and potentially inhibiting cancer progression by modulating EMT-related proteins.

Inhibitory effects of chlorhexidine-loaded calcium carbonate nanoparticles against dental implant infections

This study aimed to design sustained released biodegradable calcium carbonate nanoparticles loaded with chlorhexidine (CHX-loaded NPs) and to investigate the early osteogenic differentiation and antimicrobial effects on the important bacteria involved in infections of dental implants. The microemulsion method was used to prepare the calcium carbonate nanoparticles loaded with chlorhexidine. The prepared nanoparticles were characterized using conventional methods. The release pattern determination and the biodegradation test were performed for the prepared nanoparticles. For the early osteogenic differentiation test of the prepared nanoparticles, alkaline phosphatase (ALP) activity was detected in human dental pulp stem cells (HDPSCs). The antimicrobial effects of the nanoparticles were evaluated against Escherichia coli, Streptococcus mutans, Enterococcus faecalis, Staphylococcus aureus, and Pseudomonas aeruginosa. The sizes of free calcium carbonate nanoparticles and CHX-loaded NPs were 105 ± 1.63 and 118 ± 1.47 nm and their zeta potentials were − 27 and − 36, respectively. A 50% degradation of nanoparticles was achieved after 100 days. These nanoparticles showed a two-stage sustained release pattern in vitro. Microscopic images revealed that the morphology of free calcium carbonate nanoparticles primarily took on a spherical calcite form, while CHX-loaded NPs predominantly exhibited a cauliflower-like vaterite polymorph. The nanoparticles increased the activity of ALP in cells in two weeks significantly (p < 0.05). Antimicrobial and antibiofilm results showed an efficient effect of the prepared nanoparticle against the studied bacteria. Calcium carbonate nanoparticles are an efficient multifunctional vector for chlorhexidine and can be used as a bioactive antibacterial agent against various oral microorganisms to prevent implant infections.

Micro/nano additives in 3D printing concrete

3D concrete printing has attracted burgeoning interest in the construction industry for its ability to offer cost-effectiveness, architectural design flexibility, efficient use of energy and materials, as well as significant time savings in the construction process. However, conventional cement-geopolymer-based materials cannot be used directly for printing due to their lack of printability. This review explores the utilization of inorganic micro/nanomaterials to modify the rheological and mechanical performance of fresh-state and post-hardening cementitious composites, respectively, offering an in-depth analysis of the mechanisms underpinning their effects. This paper discusses a wide range of inorganic micro/nanomaterials, including carbon-based nanomaterials, silicon-based nanomaterials, metallic oxide nanomaterials, nano-calcium carbonate particles, and other micro/nano-materials. Those materials have been utilized in 3D printing concrete or show considerable potential for future applications in this field. Furthermore, this work provides insights into the multiple applications that arise from the synergistic combination of 3D printing construction techniques with the distinctive properties of different nanomaterials.

Hierarchical Integration of Curcumin-Loaded CaCO3 Nanoparticles and Black Phosphorus Nanosheets in Core/Shell Nanofiber for Cranial Defect Repair.

Reconstruction and healing of large craniofacial bone defects are major clinical challenges due to high risk of chronic inflammation and reduced cell mineralization levels. Herein, a core-shell nanofiber-based implant with significant pro-osteogenesis capability for treating skull defects is reported, which is hierarchically integrated with curcumin-loaded calcium carbonate nanoparticles (CaCO3@Cur NPs) in the outer layers and black phosphorus nanosheets (BPNSs) in the core compartments. The radical alignment of the integrated nanocomponents allows the sequential in situ release of the therapeutic agents in a controlled manner after implantation. Curcumin can repolarize M1 macrophages into M2 phenotypes for anti-inflammation purposes. Meanwhile, the released calcium and phosphate ions can promote the biomineralization of hydroxyapatite at the defect site and facilitate bone regeneration. Evaluations on cranial defect-bearing rat models demonstrated that the electrospun fibers in the present study substantially promoted restoration of the damaged skulls and inhibited inflammation in the wound bed. This strategy provides a new idea for the treatment of skull defects in the clinic.

Synthesis, characterization, and biological properties of calcium and zinc based ION incorporated amorphous carbonate nanoparticles

In this study, magnesium (Mg), zinc (Zn), and strontium (Sr) incorporated amorphous calcium carbonate (ACC) nanoparticles were synthesized. Results revealed that at low Zn concentrations, Zn and Sr co-incorporated, Mg-stabilized amorphous calcium carbonate (ACMC) nanoparticles were obtained. However, at high Zn concentrations, instead of ACMC, calcium (Ca) and Sr co-incorporated, magnesium-stabilized amorphous zinc carbonate (AZMC) nanoparticles were obtained. Our results demonstrated that Mg could be used to stabilize the amorphous structure of both nanoparticles. The additive ions could be incorporated into the structure of both ACMC and AZMC without impairing their amorphous nature. The synthesized nanoparticles had an average size of about ∼30 nm. Degradation studies suggested that the degradation rate of AZMC nanoparticles could be slower compared to ACMC nanoparticles. Antibacterial tests showed that the number of colony forming units for the Ca and Sr co-incorporated AZMC nanoparticles was lower for both Staphylococcus aureus (S. aureus), and Escherichia coli (E. coli) strains compared to the control group. Cytotoxicity studies revealed that fibroblasts interacting with the ion-incorporated ACMC and AZMC nanoparticles remained viable and proliferated for up to 5 days in vitro. These results demonstrated for the first time that Zn and Sr co-incorporated ACMC nanoparticles were non-toxic, biodegradable, and possessed antibacterial properties. In addition, Ca and Sr co-incorporated AZMC nanoparticles exhibited a stronger antibacterial effect, which makes them promising candidates for antibacterial applications.

Hybrid organic - inorganic filter system for cadmium ions adsorption from aqueous solutions

The study reflects on the problem of heavy metals, namely cadmium, polluting the natural environment. The goal was to select the most efficient adsorber enabling ion exchange between calcium and cadmium in an aqueous environment and subsequently design a material hybrid organic-inorganic, particle-fiber system that adsorbs cadmium from aqueous environments and will be easily included in the technological process. The novelty of this study lies in the use of waste food material – eggshells as a source of biogenic nanoparticles. These are applied to a nanofibrous structure made of polyvinyl butyral in amounts of 8 to 10 %wt by weight by the AC electrospinning. (The experiment was performed with these boundary conditions: temperature was 23°C, and humidity was 42%. The high-electrical voltage amplifier generated a sinusoidal waveform with a frequency of 50 Hz and an amplitude of 32 kV) and were used for ion exchange. In ion exchange, cadmium ions are exchanged with calcium ions based on the principle of chemical similarity of the two elements expressed by the z/r ratio (charge/ radius ratio), the z/r ratio is 2.02 for calcium ions Ca2+ and 2.06 for cadmium Cd2. Separateted nanoparticles of calcium carbonate obtained by burning eggshells (727°C) with dimensions from 100 to 200 nm and a specific surface area of 3.9 m2/g showed the highest adsorption capacity of 99.8%, synthetic calcium carbonate at 71.8%, and ground eggshells the lowest at 25.0%. Designed and laboratory-tested filter system of nanoparticles - nanofibers captures 95.6% and 96.8% of cadmium ions from an aqueous solution within 10 minutes and 90 minutes, respectively, at a concentration of cadmium ions of 10 mg/l, and at several nanoparticles of 0.3 g. The ion exchange is carried out only on the filter surface, and after a specific time, the calcium carbonate nanoparticles are released from the filter probably due to absence of chemical bond between nanoparticles and nanostructures or the low density of the nanofibrous structure. SEM, EDX, FTIR, BET and TGA analysis were used for material evaluation. The adsorption capacity of used nanoparticles and filter adsorbers was evaluated according to residual amounts of cadmium ions in aqueous solutions using ICP-IOS.

Biomineralization of Electrospun Bacteria-Encapsulated Fibers: A Relevant Step toward Living Ceramic Fibers.

Living ceramic materials are proposed as high-performance engineered living materials due to their expected properties, including improved mechanical stability and performance, which could impact a wide range of applications across various fields. Particularly, living ceramic fibers are anticipated to exhibit even superior mechanical and structural properties, considering their fibril nature. This work presents the foundation for developing the family of living ceramic fibers. Ureolytic bacteria, Sporosarcina pasteurii, are encapsulated within electrospun alginate fibers, which are further subjected to biomineralization. A live-dead assay reveals that the encapsulated bacteria survive the electrospinning process. Successful biomineralization of the fibers results in the precipitation of near-spherical calcium carbonate nanoparticles at the fiber sites. The cell density within the fibers exhibits a significant impact on the packing of calcium carbonate nanoparticles. While further extensive research is required to fully realize the potential of living ceramic fibers, the findings of this study represent a significant step toward their development.

5-Fluorouracil in Combination with Calcium Carbonate Nanoparticles Loaded with Antioxidant Thymoquinone against Colon Cancer: Synergistically Therapeutic Potential and Underlying Molecular Mechanism.

Colon cancer is the third most common cancer worldwide, with high mortality. Adverse side effects and chemoresistance of the first-line chemotherapy 5-fluorouracil (5-FU) have promoted the widespread use of combination therapies. Thymoquinone (TQ) is a natural compound with potent antioxidant activity. Loading antioxidants into nano delivery systems has been a major advance in enhancing their bioavailability to improve clinical application. Hence, this study aimed to prepare the optimal TQ-loaded calcium carbonate nanoparticles (TQ-CaCO3 NPs) and investigate their therapeutic potential and underlying molecular mechanisms of TQ-CaCO3 NPs in combination with 5-FU against colon cancer. Firstly, we developed purely aragonite CaCO3 NPs with a facile mechanical ball-milling method. The pH-sensitive and biocompatible TQ-CaCO3 NPs with sustained release properties were prepared using the optimal synthesized method (a high-speed homogenizer). The in vitro study revealed that the combination of TQ-CaCO3 NPs (15 μM) and 5-FU (7.5 μM) inhibited CT26 cell proliferation and migration, induced cell apoptosis and cell cycle arrest in the G0/G1 phase, and suppressed the CT26 spheroid growth, exhibiting a synergistic effect. Finally, network pharmacology and molecular docking results indicated the potential targets and crucial signaling pathways of TQ-CaCO3 NPs in combination with 5-FU against colon cancer. Therefore, TQ-CaCO3 NPs combined with 5-FU could enhance the anti-colon cancer effects of 5-FU with broader therapeutic targets, warranting further application for colon cancer treatment.

Additive application for modulating physicochemical properties and antitumor effects of CaCO3 nanodelivery systems

Calcium carbonate (CaCO3) nanoparticles are highly regarded for their excellent biocompatibility and distinctive pH responsiveness, making them an ideal nanocarrier system for anti-tumor therapy. The incorporation of additives during the preparation of CaCO3 can significantly influence its morphology, particle size, and tumor inhibitory effects, necessitating a systematic study of these impacts. This study utilized the gas diffusion method to prepare CaCO3 nanoparticles, introducing various additives such as hyaluronic acid, polyacrylic acid, polyvinyl pyrrolidone, fucoidan, and polyethyleneimine. Different additives were found to have diverse effects on the morphology, particle size, zeta potential, and pH responsiveness of CaCO3. Methotrexate was employed as a model drug to evaluate the cytotoxicity of CaCO3 nanoparticles with different additives. Among them, hyaluronic acid-modified CaCO3 nanoparticles exhibited ideal morphology, particle size, significant pH responsiveness, and tumor-targeting capabilities. In vitro and in vivo experiments demonstrated their remarkable antitumor effects.

Highly Graphitized Coal Tar Pitch-Derived Porous Carbon as High-Performance Lithium Storage Materials.

Because of its high specific capacity and superior rate performance, porous carbon is regarded as a potential anode material for lithium-ion batteries (LIBs). However, porous carbon materials with wide pore diameter distributions suffer from low structural stability and low electrical conductivity during the application process. During this study, the calcium carbonate nanoparticle template method is used to prepare coal tar pitch-derived porous carbon (CTP-X). The coal tar pitch-derived porous carbon has a well-developed macroporous-mesoporous-microporous hierarchical porous network structure, which provides abundant active sites for Li+ storage, significantly reduces polarization and charge transfer resistance, shortens the diffusion path and promotes the rapid transport of Li+. More specifically, the CTP-2 anode shows high charge capacity (496.9 mAh g-1 at 50 mA g-1), excellent rate performance (413.6 mAh g-1 even at 500 mA g-1), and high cycling stability (capacity retention rate of about 100 % after 1,000 cycles at 2 A g-1). The clean and eco-friendly large-scale utilization of coal tar pitch will facilitate the development of high-performance anodes in the field of LIBs.

Enhanced breast cancer therapy using multifunctional lipid-coated nanoparticles combining curcumin chemotherapy and nitric oxide gas delivery

The limitations associated with conventional cancer treatment modalities, particularly for breast cancer, underscore the imperative for developing safer and more productive drug delivery systems. A promising strategy that has emerged is the combination of chemotherapy with gas therapy. We synthesized curcumin-loaded amorphous calcium carbonate nanoparticles (Cur-CaCO3) via a gas diffusion reaction in the present study. Subsequently, a "one-step" ethanol injection method was employed to fabricate lipid-coated calcium carbonate nanoparticles (Cur-CaCO3@LA-Lip) loaded with L-arginine, aimed at harnessing the synergistic effects of chemotherapy and nitric oxide to enhance antitumor efficacy. Transmission electron microscopy analysis revealed that Cur-CaCO3@LA-Lip nanoparticles were subspherical with a distinct lipid layer encapsulating the periphery. Fourier transform infrared spectroscopy, X-ray powder diffraction, and differential scanning calorimetry results confirmed the successful synthesis of Cur-CaCO3@LA-Lip. The nanoparticles exhibited significant drug loading capacities of 8.89% for curcumin and 3.1% for L-arginine. In vitro and in vivo assessments demonstrated that Cur-CaCO3@LA-Lip nanoparticles facilitated sustained release of curcumin and exhibited high cellular uptake, substantial tumor accumulation, and excellent biocompatibility. Additionally, the nanoparticles showed robust cytotoxicity and potent antitumor efficacy, suggesting their potential as a formidable candidate for breast cancer therapy.

Customizable Hydrogel Coating of ECM-Based Microtissues for Improved Cell Retention and Tissue Integrity.

Overcoming the oxygen diffusion limit of approximately 200 µm remains one of the most significant and intractable challenges to be overcome in tissue engineering. The fabrication of hydrogel microtissues and their assembly into larger structures may provide a solution, though these constructs are not without their own drawbacks; namely, these hydrogels are rapidly degraded in vivo, and cells delivered via microtissues are quickly expelled from the area of action. Here, we report the development of an easily customized protocol for creating a protective, biocompatible hydrogel barrier around microtissues. We show that calcium carbonate nanoparticles embedded within an ECM-based microtissue diffuse outwards and, when then exposed to a solution of alginate, can be used to generate a coated layer around the tissue. We further show that this technique can be fine-tuned by adjusting numerous parameters, granting us full control over the thickness of the hydrogel coating layer. The microtissues' protective hydrogel functioned as hypothesized in both in vitro and in vivo testing by preventing the cells inside the tissue from escaping and protecting the microdroplets against external degradation. This technology may provide microtissues with customized properties for use as sources of regenerative therapies.

Exploring the Therapeutic Potential of 5-Fluorouracil-Loaded Calcium Carbonate Nanoparticles Combined with Natural Compound Thymoquinone for Colon Cancer Treatment.

Given the need for novel and effective therapies for colon cancer, this study aimed to investigate the effects of 5-fluorouracil-loaded calcium carbonate nanoparticles (5FU-CaCO3np) combined with thymoquinone (TQ) against colon cancer. A shaking incubator and a high-speed homogenizer were used to prepare the optimal 5FU-CaCO3np, with characterizations of physicochemical properties, in vitro drug release profile, and biocompatibility. In vitro experiments and molecular docking were employed to evaluate the therapeutic potential of the combination for colon cancer treatment. Study results revealed that 5FU-CaCO3np with a size of approximately 130 nm was synthesized using the high-speed homogenizer. Its favorable biocompatibility, pH sensitivity, and sustained release properties facilitated reduced toxic side effects of 5-FU on NIH3T3 normal cells and enhanced inhibitory effects on CT26 colon cancer cells. The combination of 5FU-CaCO3np (1.875 μM) and TQ (30 μM) showed significantly superior anti-colon cancer effects to 5FU-CaCO3np alone in terms of cell proliferation and migration inhibition, cell apoptosis induction, and spheroid growth suppression in CT26 cells (p < 0.05), with strong interactions between the drugs and targets (E-cadherin, Bcl-2, PCNA, and MMP-2). These results provide evidence for 5FU-CaCO3np as a novel regimen against colon cancer. Combining 5FU-CaCO3np and TQ may offer a new perspective for colon cancer therapy.

Influence of additive nano calcium carbonate (CaCO3) on SAE 10W-30 engine oil: A study on thermophysical, rheological and performance

Researchers have used nanomaterials as additives in base oil to improve its specifications, especially to minimize wear and friction during its applications. In this study, calcium carbonate (CaCO3) nanoparticles were selected as an additive to serve as a protective layer between components and anti-wear properties. In this study, calcium carbonate (CaCO3) nanoparticles were selected as an additive to serve as a protective layer between components and anti-wear properties. Nano lubricant samples were prepared using mass variations of CaCO3 and SAE 10W-30 base oil with concentrations of 0.05, 0.1, 0.15, and 0.2%, then homogenized. The nanolubricant samples obtained were analyzed for thermophysical, rheological properties and lubricant performance with the addition of nano CaCO3 in improving the wear resistance of FC25 cast iron. The results of thermophysical and rheological properties analysis suggest that the nanolubricant has better tribological properties compared to base lubricants. The highest values of thermal conductivity, density, and viscosity (40 oC) are 0.139 W/m.K, 812.203 kg/m3, and 106 mPa.s (40 oC). Meanwhile, the highest CoF, disc mass loss, and surface roughness of nanolubricant are 0.0706, 0.0037 grams, and 0.50 µm, respectively. These results indicate that the greatest wear-reducing agent is from the nanolubricant with the addition of CaCO3 nanopowder additives at 0.1 wt% concentration. These results are expected to give significant insights into the advancement of nano technology-based lubricants in the future.

Development of Hydrophilic Self-Cleaning and Ultraviolet-Shielding Coatings Incorporating Micro-Titanium Dioxide/Nano-Calcium Carbonate (µ-TiO&lt;sub&gt;2&lt;/sub&gt;)/(Nano-CaCO&lt;sub&gt;3&lt;/sub&gt;)

The dust accumulation and dirt particles always degrade the transparency of glass, later hampers its various applications such as photovoltaic panels, building glass, and car-windshield. In this study, the hydrophilic self-cleaning coatings have been developed by using the nanocalcium Carbonate particles (nanoCaCO3) and hydrophilic micro-titanium dioxide particles (µ-TiO2). The presence of oxide groups, CO-3 and TiO2- forms a strong attraction of glass to polar water molecules. At the weight ratio of 1: 1 in the CaCO3 to TiO2 mixture, it forms a great hydrophilic property in which the water contact angle (WCA) of coated glass has been recorded as low as 11.46 ±0.85°. The coated glass also showed high transparency in UV and Visible regions. The optical transmission of coated glass was above 89% at the wavelength of 300-400nm and above 97% at the wavelength of 400-800nm. Due to its hydrophilic property, the coated glass is capable of removing the dust particles away via the water stream. The hydrophilic coating spontaneously forms the water-thin film after contact with coated glass without the presence of UV light.
