Under the best conditions, law Beer’s lambert was obeyed in the concentration of two drugs range of 1–20 mg/L (R2 = 0.9984), (R2 = 0.9965), and lead to obtain the limit of quantitation (LoQ) (μg mL-1) 0.155 and 0.138, and limit of detection (LoD) (μg mL-1) 0.517 and 0.461, adrenaline, dopamine at the same order. The proposed process was applied and validated to estimate adrenaline and dopamine in several samples of pharmaceutical preparations.

A benzoxazole-based turn-on fluorosensor for rapid and sensitive detection of sarin surrogate, diethylchlorophosphate

A benzoxazole-based fluorosensor (IMP) has been synthesized and employed for the selective and sensitive detection of sarin surrogate, diethylchlorophosphate (DCP) in solution, and gas phase, respectively. Remarkable turn-on fluorescence is observed due to the introduction of DCP in the solution of IMP because of inhibition of the intramolecular charge transfer process and disruption of the excited state intramolecular proton transfer (ESIPT) mechanism. The synthesized IMP-based fluorescence sensor exhibits excellent selectivity, high sensitivity, and a wide linear range of 15–60 μM with a detection limit of 44 nM. Low-intense to highly intensified visible violet color could be seen by the naked eye under a portable 365 nm UV lamp due to the addition of DCP in the solution of IMP. IMP-stained paper strips-based test kit experiment has been demonstrated to detect traces of DCP in stockpiles of related analytes. A dip-stick experiment for the detection of DCP vapor has also been demonstrated. The effectiveness of IMP in detecting DCP established that it might be used as a signal tool for real sample analysis.

Synthesis of green emitted carbon dots from Vachellia nilotica and utilizing its extract as a red emitted fluorescence reagent: Applying for visual and spectroscopic detection of iron (III)

Principles of Green Analytical Chemistry recommended preferring using reagents from renewable sources and eliminating toxic reagents. Vachellia nilotica is a widespread plant throughout different parts of the world. In this study, using microwave energy, fluorescent carbon dots were synthesized for the first time from Vachellia nilotica pods. The morphology of the prepared carbon dots was characterized by SEM and TEM techniques, and the spectroscopic character exhibit green emission at 480 nm at λex = 386.5 nm. This fluorescence can be effectively quenched by adding Fe (III) ions (Method I). Furthermore, Vachellia nilotica pods were extracted by different solvents, including methanol, deionized water, absolute ethanol, acetone, acetonitrile, and DMF. The acetonitrile extract of Vachellia nilotica exhibited a strong red fluorescence emission at 673.9 at λex = 410 nm. Among various types of salt metals, only Fe (III) can effectively quench the fluorescence intensity of the acetonitrile extract (method II). Moreover, the bright yellow color of the aqueous extract can be changed into violet color. The absorbance of the resulted color can be spectrophotometrically measured at λ max = 530 nm (method III). The best analytical factors were optimized for the developed methods. The developed methods were applied to determine Fe (III) in different water samples.

Structural Colors on Al Surface via Capped Cu-Si3N4 Bilayer Structure

Tunable structural colors have a multitude of applications in the beautification of mobile devices, in the decoration of artwork, and in the creation of color filters. In this paper, we describe a Metal-Insulator-Metal (MIM) design that can be used to systematically tune structural colors by altering the thickness of the top metal and intermediate insulator. Cu and Si3N4 were selected as the top metal and intermediate insulator layers, respectively, and various reflection colors were printed on Al. To protect the Cu surface from scratchiness and oxidation, a number of capping layers, including SiO2, LPSQ, PMMA, and the commercially available clear coat ProtectaClear, were applied. In addition to their ability to protect Cu from a humid environment without deteriorating color quality, ProtectaClear and LPSQ coatings have minimal angle dependency. Furthermore, a bilayer of PMMA/SiO2 can protect the Cu surface from the effects of humidity. In addition, the PMMA/SiO2 and ProtectaClear/SiO2 bilayers can also protect against corrosion on the Cu surface. The colors can be tuned by controlling the thickness of either the metal layer or intermediate insulator layer, and vivid structural colors including brown, dark orange, blue, violet, magenta, cyan, green-yellow, and yellow colors can be printed. The measured dielectric functions of Cu thin films do not provide any evidence of the plasmonic effect, and therefore, it is expected that the obtained colors are attributed to thin-film interference.

Development of an analytical chip for colorimetric detection of medium-chain aldehydes by reaction with pararosaniline in porous glass

Medium-chain aldehydes are common human biogases that can be detected in the breath of patients with lung diseases. As such, the measurement of medium-chain aldehyde gases in human breath can provide significant, noninvasive, and diagnostic information related to the potential presence of such diseases. In this study, an analytical chip is developed for the detection of medium-chain aldehydes without interference from short-chain aldehydes. This analytical chip is composed of porous glass impregnated with pararosaniline and an acid (i.e., acetic acid with small amount of phosphoric acid). After exposure to medium-chain aldehydes, the red analytical chip became violet in color, and an absorption peak was observed at 620 nm. It was found that a non-reversible reaction occurred in the porous glass, therefore, the analytical chip functions in a cumulative manner. A linear relationship was determined between the absorbance change of the analytical chip at 620 nm and the nonanal exposure concentration. Importantly, the developed analytical chip successfully detected nonanal at concentrations of 8–270 ppb as calculated from the absorbance change at 620 nm after a 24 h exposure time. In addition, nonanal concentration was estimated using the change in the R value of the analytical chip photograph. This method is suitable for point-of-care breath analysis. Finally, the analytical chip was also found to be active toward octanal and decanal with a relative sensitivity of 0.7 compared to that of nonanal; it was not active toward short-chain aldehydes.

Resonance Raman and Visible Micro-Spectroscopy for the In-Vivo and In-Vitro Characterization of Anthocyanin-Based Pigments in Blue and Violet Flowers: A Comparison with HPLC-ESI- MS Analysis of the Extracts

Microanalysis techniques based on resonance Raman and reflection visible spectroscopy have been applied to the characterization of pigments responsible for the blue or violet coloration in flowers; in particular of Lobelia erinus, Campanula portenschlagiana, Cineraria, Viola tricolor, Anemone coronaria, Agapanthus, Platycodon, Salvia farinacea, Plumbago capensis, Ceratostigma plumbaginoides, Commelina communis and Salvia patens. The spectroscopic methods were applied both in vivo on the flower petals and in vitro on extracts obtained through a procedure based on SPE (solid-phase extraction) optimized for minimal quantities of vegetable raw material. Different patterns obtained for the Raman spectra have been correlated, also on the basis of density functional theory (DFT) calculations, with different schemes of substitution of the benzopyrilium nucleus of the anthocyanins and with various possible forms of copigmentation responsible for the stabilization of the blue color. The results obtained were verified by comparison with the analysis of the extracts by HPLC-ESI-MS (liquid chromatography-electrospray ionization-mass spectrometry).

Magneto recyclable, green fabricated Fe3O4 nanorods on photo responsive of textile dye degradation and identification products by LC-MS

Prior to being released towards water sources such as rivers, lakes, and groundwater, the efficient technique of removing color out textile effluents seems to have become widely used. Such contaminants are extremely difficult for traditional wastewater treatment methods to completely eliminate. This innovative development of phytonutrients uses Fe3O4 nanorods, that have been employed as photocatalytic to change substrate colors in the aqueous layer when exposed to light. Given prominence was adopted to incorporate phytonutrients with Fe3O4 nanorods. The degradation of the methyl violet colour has been acknowledged by the depletion of the UV light (UV) absorption edge that also originated at 581 nm. The significant colour expulsion of the Fe3O4 nanorod was proved to really be 97% after 60 min. The findings demonstrate that ecologically responsible Fe3O4 nanorods are immensely beneficial in the photocatalytic reaction of harmful pollutants.

First Report of Fusarium oxysporum Causing leaf spot on Basella rubra in Malaysia.

Basella rubra (family Basellaceae), locally known as 'Remayong Merah', is an edible perennial vine served as leafy greens in Malaysia. In May 2021, leaves with circular brown spots ranging from 3 to 10 mm wide with purple borders were found on B. rubra growing in Penampang (5°56'55.6"N 116°04'33.5"E), Sabah province. The disease severity was 80% with 10% disease incidence on 50 plants. As the disease developed, the lesions grew larger and they developed necrotic centers. Leaves with brown spot symptoms from five plants were collected from the field. Five leaf pieces (5 x 5 mm) were excised from lesion margins, surface sterilized based on Khoo et al. (2022b), before incubation on water agar at 25°C. When five pure cultures were obtained, the fungi were cultured on potato dextrose agar (PDA) at 25°C. After 5 days, fluffy white mycelia tinged with pink pigmentation showing on the underside of the colony were observed on PDA. Mycelia became violet in color as the culture aged. The isolates were incubated on carnation leaf agar at 25°C with a 12-hour light/dark photoperiod for 10 days. Sickle-shaped, thin-walled and delicate macroconidia (n= 30), predominantly 3 septate, ranging from 21.6 to 38.3 μm long by 2.7 to 4.2 μm wide in size were observed. Kidney-shaped, aseptate microconidia (n= 30) ranged from 6.2 to 11 μm long by 2.6 to 3.9 μm wide in size, and were formed on monophialides in false heads. Chlamydospores were detected both terminally and intercalarily, singly or in pairs, with smooth or rough walls. Genomic DNA was extracted from fresh mycelia of a representative isolate from Penampang based on Khoo et al. (2022a). The primers ITS1/ITS4 (White et al. 1990) and EF1/EF2 (O'Donnell et al. 1998) were used to amplify the internal transcribed spacer (ITS) rDNA and translation elongation factor 1-α (TEF1α) region, respectively based on PCR conditions as described previously (Khoo et al. 2022b). The products were sent to Apical Scientific Sdn. Bhd. for sequencing. In BLASTn analysis, ITS sequence (OK469301) was 99% (506/507 bp) identical to isolate TSE07 (MT481761) of Fusarium oxysporum, and the TEF1α sequence (OM743433) was 100% (705/705 bp) identical to isolate BLBL5 of Fusarium oxysporum. The TEF1α sequence of Penampang was analyzed at the Fusarium MLST site (https://fusarium.mycobank.org/), and had 98% similarity to TEF1α of F. oxysporum (NRRL 22551). The pathogen was identified as F. oxysporum based on morphological (Leslie and Summerell 2006) and molecular data. A volume of 0.16 ml of spore suspensions (1 × 106 conidia/ml) were inoculated on a spot on each leaf of every three healthy B. rubra seedlings at the two-leaf stage. An additional three B. rubra seedlings were mock inoculated by pipetting sterile distilled water on similar aged leaf. The seedlings were maintained in a greenhouse at 25°C with a relative humidity of 80 to 90%. Six days after inoculation, all inoculated leaves exhibited the same symptoms as observed in the field, while the controls showed no symptoms. The experiment was repeated two more times. The reisolated fungi had the same morphology and DNA sequences as the original isolate obtained from the field samples, completing Koch's postulates. F. oxysporum has been reported previously in Bangladesh and India causing leaf spot disease on B. rubra (Dhar et al. 2015; Shova et al. 2020). To our knowledge, this is the first report of F. oxysporum causing leaf spot on B. rubra in Malaysia. The identification of leaf spot caused by F. oxysporum will enable plant health authorities and farmers to identify practices to minimize disease on this important crop.

DETERMINATION OF ANTHOCYANIN LEVEL IN KIDNEY BEAN (Phaseolus vulgaris L.) TEMPEH AS A HEPATOPROTECTIVE AGENT

Liver is a part of body that is used as a toxin neutralizer as well as a target for increasing free radicals. In counteracting free radicals, body needs antioxidants in one of the plant secondary metabolites, namely anthocyanins. Anthocyanins are organic compounds from the water-soluble flavonoid family that give red, blue, and violet colors. Fermentation can increase anthocyanin levels in kidney beans. This study aimed to determine the presence of anthocyanins in kidney bean (Phaseolus vulgaris L.) tempeh which can be used as a hepatoprotective agent and to determine the anthocyanin levels in kidney bean (Phaseolus vulgaris L.) tempeh. Qualitative analysis using HCl and NaOH with positive results showed the color change to solid red then to bluish green and then faded. Determination of total anthocyanin levels was carried out using UV-Vis spectrophotometric method with the pH differential principal in anthocyanin showed in mg/100gram sample at a maximum wavelength of 525.5 nm. The result was that the average anthocyanin content was 40.37mg/100gram with a variant coefficient is 0.325%.

Enzyme-free and wide-range portable colorimetric sensing system for uric acid and hydrogen peroxide based on copper nanoparticles

Uric acid (UA) is the final product of purine metabolism. A high concentration of UA in body fluid may lead to kidney stones, gout, and some cardiovascular diseases. Therefore, the non-invasive daily monitoring of UA is of great significance for both hyperuricemia patients and fit people. However, most of the current detection methods for UA are enzyme-dependent which limits the application scenarios and lacks portable instruments for on-site detection, including optics and electrochemistry. In this work, an enzyme-free and wide-range colorimetric sensor for UA and H2O2 detection was developed based on a mercaptosuccinic acid (MSA)-modified Cu nanoparticles (CuNPs). Under the action of UA or H2O2, with the cleavage of MSAs on the CuNPs surface, small Cu particles are further aggregated into larger particles with a lightning violet color. With the employment of the multi-channel handheld automatic photometer (MHAP), the concentration of UA and H2O2 can be determined on-site according to the absorbance measurement by the photodiodes. The linear range of UA was 5 μM-4.5 mM with the limit of detection (LOD) of 3.7 μM, while the linear range of H2O2 was 5 mM–500 mM and 5 μM-5 mM with the LOD of 4.3 μM. This approach has been applied to the detection of UA in human urine, providing more possibilities for non-invasive home health monitoring, community medical diagnosis, and broader prospects of on-site disease detection.

Biogenic Synthesis of Silver-Iron Oxide Nanoparticles Using Kulekhara Leaves Extract for Removing Crystal Violet and Malachite Green Dyes from Water

Crystal violet and malachite green, cationic dyes, are widely used in various industries. Water-containing dye molecules affect human health and aquatic life. Here, we synthesized silver-iron oxide nanoparticles using an aqueous extract of kulekhara leaves. The main advantage of this synthesis is that no iron salts were used to prepare Ag-iron oxide nanoparticles. Iron-rich Kulekhara leaves provide iron oxide during the in situ formation of silver nanoparticles. Synthesized Ag-Fe2O3 nanoparticles were characterized by UV-Vis, FTIR, XRD, and STEM-Cs. The dye-degradation studies were performed using synthesized nanoparticles in the presence of sodium borohydride. In the catalytic reaction, the color of crystal violet and malachite green disappeared (100%) within three minutes, and the same results were obtained in their mixtures (1:1 v/v). The presence of Fe2O3 in AgNPs may boost the rapid reduction in azo bonds due to the higher exposed surface area. The color changes were monitored using UV-Vis spectroscopy. Comparative literature studies showed that the performance of Ag-Fe2O3 is superior regarding the degradation of malachite green and crystal violet. These findings could entice researchers to design and develop various dye degradation using this eco-friendly process.

The Greening of Anthocyanins: Eco-Friendly Techniques for Their Recovery from Agri-Food By-Products.

In recent years, several steps forward have been made toward a more sustainable approach for the extraction of bioactive compounds from plant materials based on the application of green extraction principles. It is currently recognized that waste and by-products deriving from agriculture and food industries still contain a wide array of high value-added substances, which can be re-used to obtain new products with various applications in the food, supplement, pharmaceutical, and cosmetic industries. Anthocyanins are a class of these valuable metabolites; they confer the red, violet, and blue color to fruits and vegetables, and scientific evidence has accumulated over the last few decades to support their beneficial effects on human health, in great part deriving from their powerful antioxidant capacity. This review provides a general overview of the most recent green procedures that have been applied for the recovery of anthocyanins from plant-derived wastes and by-products. The most widely used green solvents and the main sustainable techniques utilized for recovering this class of flavonoids from various matrices are discussed, together with the variables that mainly impact the extraction yield.

Discovery, Development and Design of Anthocyanins-Inspired Anticancer Agents: A Comprehensive Review.

Mother Nature is an indispensable source of bioactive natural products. Bioactive secondary metabolites have played a crucial role in the drug development and discovery process; mainly, anticancer and antibiotic molecules are extensively enriched with molecules of natural origin. Anthocyanins are water-soluble secondary metabolites found in most species in the plant domain, especially flowers, fruits, and tubers. These natural vacuolar pigments belong to the chemical class of phenolic moieties, which are responsible for the shiny orange, red, blue, pink, and violet colors in the fruits, flowers, and vegetables. Chemically, anthocyanins comprise a core structure in the form of flavylium cation or 2-phenylbenzopyrylium, and these natural colorants are polyhydroxy and polymethoxy analouges of this flavylium cation and can have sugar moieties or acylated groups linked at different positions. Currently, these molecules have raised a growing interest because of their wide range of colors, innocuous and beneficial health effects, and commercial application in functional foods, nutraceuticals, pharmaceutical and cosmetic industries. However, interest in anthocyanin derivatives has noticeably enhanced in recent years due to their higher stability, improved bioavailability in biological matrices, and better use in food matrices and cosmetic products. Due to the enormous potential of natural anthocyanins and their derivatives, this review tries to cover syntheses of anthocyanins and their analogues, chemical derivatization of anthocyanins, and anticancer activities, such as breast, colorectal, leukemia, lung, prostate, and skin cancer of anthocyanins efficiently.

Study of Anthocyanin Extraction from Red Banana (Musa sapientum L. var Rubra) Waste and Characteristics of Light Effects

Anthocyanins are compounds responsible for plants’ blue, purple, violet, magenta, red, and orange colours. Anthocyanins are found in tropical fruits. Generally, anthocyanins are found in the peel tissues of plants. The increasing interest in anthocyanins, especially in the field of food and health, supports the development of anthocyanin exploration research. One of the uses of anthocyanins that are widely developed today is the addition of anthocyanins as indicators in smart packaging. For application on the packaging, in addition to extraction techniques, it is also necessary to assess the characteristics of anthocyanins in the environment. This study aims to examine the anthocyanin potential of red banana waste and the effect of light on anthocyanin stability. The anthocyanins observed are the result of anthocyanin extraction from the red banana peel and bracts using the maceration method. The solvent used is water acidified with citric acid. The study results showed that the total anthocyanin content in red banana bracts extract was higher than in extract from red banana peel. A concentrated extract from the bracts of a red banana contains 114.26 μg/g FW of total anthocyanins. In comparison, the concentrated extract of red banana peel contains 110.27 μg/g FW of total anthocyanins. Identification of concentrated extracts of red banana peel and flower through FTIR test, maximum wavelength test with UV-Vis and discolouration test showed that the extract contains anthocyanin compounds. Irradiation with a 25-watt bulb lamp, UV lamp and sunlight on concentrated extracts of the red banana peel and bracts showed degraded anthocyanin content. The results of this study show that the peel and flower of red bananas have the potential to be developed as a source of anthocyanins.

The concentration effect of Ce3+ ions on the photoluminescence properties of the host sensitized NaMPO4-Ce3+ (M = Mg and Ca) phosphors via solid-state reaction method

A series of Ce3+ doped NaMPO4 (M = Mg and Ca) nanophosphors were prepared using the solid-state reaction route, annealed at 900 °C for 4 h (except for NaMgPO4 which was annealed at 780 °C for 4 h). In this study, the concentration effects of Ce3+ ions for x = 0.0, 0.1, 0.5, 1.0, 1.5 and 2.0 mol% were investigated for its structural and photoluminescence (PL) properties. The structural and PL properties of the NaMPO4:xCe3+ compounds were analyzed using different characterization techniques, such as X-Ray diffraction (XRD), Field Emission Scanning Microscopy (FE-SEM), UV–vis diffuse reflection spectroscopy (DRS), Fourier Transform Infrared Spectroscopy (FTIR), PL and International Commission on Illumination (CIE) colour coordinates. XRD results confirm the prepared phosphors were crystallized into monoclinic (NaMgPO4) and orthorhombic (NaCaPO4) structures. SEM results confirm that all prepared samples were formed in the micrometer dimension range, with different sizes and shapes. Energy dispersive X-ray spectroscopy (EDS) spectra confirm the presence of chemical elements in the prepared nanophosphors. The presence of all phosphate (PO43−) and other structural groups were confirmed through FTIR measurements. UV–vis DRS measurements were used to calculate the optical band gap energy values via the Kubelka-Munk function theory. The PLE spectra of the NaMPO4:xCe3+ phosphors were measured in the 200–300 nm range by monitoring their peak at the 385 nm emission wavelength. Using 281 nm excitation wavelength, the PL spectra were measured and a high intensity emission band was found at the 385 nm wavelength (violet colour region). Using PL data of all NaMPO4:xCe3+ ion nanophosphors, the CIE colour coordinates were calculated and were found to lie in the violet colour region of the CIE colour diagram. From all the PL results, it is noticed that enhanced violet colour emissions were observed for all NaMPO4:xCe3+ compounds with increasing Ce3+ ion concentrations, implying that NaMPO4:xCe3+ phosphors are potential candidates for violet colour emitting technologies in display systems.
