Electrochemical aptasensor with signal amplification strategy of covalent organic framework-derived carbon material for ultrasensitive determination of carbendazim

The inadequate conductivity inherent in some covalent organic frameworks (COFs) presents a challenge for their practical use in electrochemical sensors. To enhance the electrical conductivity of COFs, a high-temperature carbonization process can be employed to carbonize COFs in an inert atmosphere, resulting in the production of COF-derived porous carbon materials. In this study, a highly conductive COF-derived carbon material (COF-T800) was obtained through the calcination of a COF known as TPB-DMTP-COF. Cyclic voltammetry (CV) current responses of the TPB-DMTP-COF electrode, when exposed to [Fe(CN)6]3−/4−, were found to be lower compared to those of a bare glassy carbon electrode (GCE). However, after the carbonization of TPB-DMTP-COF, the COF-T800 electrode exhibited significantly higher current responses than bare GCE. The oxidation current response of COF-T800/GCE in [Fe(CN)6]3−/4− was 3.3 times higher than that of TPB-DMTP-COF, demonstrating superior conductivity for this carbonized material. Subsequently, COF-T800 was employed as an electrochemical aptasensor substrate for signal amplification. This aptasensor had ultrasensitive determination of carbendazim (CBZ) with a linear response from 1.0 × 10−12 to 1.0 × 10−7 M. The detection limit of CBZ was 4.0 × 10−13 M. This aptasensor demonstrated high selectivity and applicability for CBZ. The COF-T800-based electrochemical aptasensor was utilized for detecting CBZ in actual samples with success.

Metal organic framework (MOF): Synthesis and fabrication for the application of electrochemical sensing

Metal-organic frameworks (MOF) are a class of porous hybrid materials of metal ions linked by organic bridging ligands.

These porous materials possess high surface area, variable pore sizes, various functions, and excellent thermal stability. As a result, these unique and tailored MOF materials found varied applications in electrochemical sensor development. The review critically examines the approach to synthesizing a wide range of MOF compounds. The utilization of MOF in fabricating a small-scale sensor device demonstrates the ability to detect various water contaminants in aquatic environments. Moreover, it showcased an in-depth advancement in sensor and device development utilizing MOFs materials. The efficient use of electrochemical sensors is discussed critically and presents these studies’ challenges and future perspectives.

Current perspectives, challenges, and future directions in the electrochemical detection of microplastics.

Microplastics (5 μm) are a developing threat that contaminate every environmental compartment. The detection of these contaminants is undoubtedly an important topic of study because of their high potential to cause harm to ecosystems. For many years, scientists have been assiduously striving to surmount the obstacle of detection restrictions and minimize the likelihood of receiving results that are either false positives or false negatives. This study covers the current state of electrochemical sensing technology as well as its application as a low-cost analytical platform for the detection and characterization of novel contaminants. Examples of detection mechanisms, electrode modification procedures, device configuration, and performance are given to show how successful these approaches are for monitoring microplastics in the environment. Additionally included are the recent developments in nanoimpact techniques. Compared to electrochemical methods for microplastic remediation, the use of electrochemical sensors for microplastic detection has received very little attention. With an overview of microplastic electrochemical sensors, this review emphasizes the promise of existing electrochemical remediation platforms toward sensor design and development. In order to enhance the monitoring of these substances, a critical assessment of the requirements for future research, challenges associated with detection, and opportunities is provided. In addition to-or instead of-the now-in-use laboratory-based analytical equipment, these technologies can be utilized to support extensive research and manage issues pertaining to microplastics in the environment and other matrices.

Quantification of Statins in Pharmaceutical Products Using Screen-Printed Sensors Based of Multi-Walled Carbon Nanotubes and Gold Nanoparticles

This study describes the use of electrochemical sensors to detect and quantify several statins (rosuvastatin and simvastatin) in pharmaceutical products. Two types of commercially screen-printed sensors were used and compared: one based on carbon (SPCE) and the other modified with gold nanoparticles and multi-walled carbon nanotubes (SPE/GNP-MWCNT). Cyclic voltammetry was employed for determination. The AuNP-MWCNTs/SPCE sensor outperformed the SPCE sensor, displaying excellent electrochemical properties. It demonstrated high sensitivity with low limits of detection (LOD) and quantification (LOQ) values: 0.15 µM and 5.03 µM, respectively, for rosuvastatin and 0.30 µM and 1.01 µM, respectively, for simvastatin. The sensor had a wide linear range of 20–275 µM for rosuvastatin and 50–350 µM for simvastatin. Using the AuNP-MWCNTs/SPCE sensor, rosuvastatin and simvastatin were successfully quantified in pharmaceutical products. The results were validated towards producer-reported values (standardized drugs) and a conventional analysis method (FTIR). The sensor exhibited excellent stability, reproducibility, and analytical recovery ranging from 99.3% to 106.6% with a low relative standard deviation (RSD) of less than 1%. In conclusion, the AuNP-MWCNTs/SPCE sensor proved to be a reliable and sensitive tool for detecting and quantifying statins in pharmaceutical products. Its superior electrochemical properties, low LOD and LOQ values, wide linear range, and high analytical recovery make it a promising choice for pharmaceutical quality control.

Calibration-free disposable electrochemical sensor with co-facing electrodes: Theory and characterisation with fixed and changing mediator concentration

The use of electrochemical sensors containing oxidoreductase enzymes or redox-active substrates has become an area of particular interest due to its wide potential applications. This work presents the construction, theory and characterisation of a calibration-free disposable electrochemical sensor with co-facing electrodes. Each co-facing electrode is used as an anode or cathode to achieve high sensitivity based on a reversible redox mediator-recycling signal amplification system. Furthermore, this system can simultaneously report on the concentration and diffusion coefficient of the limiting electrochemical mediator. Supporting experimental evidence is provided in systems where the viscosity of the solution is systematically varied. The theory for a constant limiting electrochemical mediator concentration is presented and extended to treat the case where the mentioned concentration increases linearly with time. The theory is applied to three specific cases to validate the developed theory. The sensor presented in this paper may be applied to developing novel low-volume and high-sensitivity disposable, point-of-care electrochemical biosensors.

Electrochemical and Optical Sensors for the Detection of Chemical Carcinogens Causing Leukemia

The incidence and mortality due to neoplastic diseases have shown an increasing tendency over the years. Based on GLOBOCAN 2020 published by the International Agency for Research on Cancer (IARC), leukemias are the thirteenth most commonly diagnosed cancer in the world, with 78.6% of leukemia cases diagnosed in countries with a very high or high Human Development Index (HDI). Carcinogenesis is a complex process initiated by a mutation in DNA that may be caused by chemical carcinogens present in polluted environments and human diet. The IARC has identified 122 human carcinogens, e.g., benzene, formaldehyde, pentachlorophenol, and 93 probable human carcinogens, e.g., styrene, diazinone. The aim of the following review is to present the chemical carcinogens involved or likely to be involved in the pathogenesis of leukemia and to summarize the latest reports on the possibility of detecting these compounds in the environment or food with the use of electrochemical sensors.

Preparation of conductive polyaniline hydrogels co‐doped with hydrochloric acid/phytic acid and their application in Ag NPs@PA/GCE biosensor for H2O2 detection

AbstractAccurate measurement of hydrogen peroxide is of great significance in monitoring human diseases and environmental safety. At present, there are a variety of testing methods, among which the use of electrochemical sensors to accurately measure hydrogen peroxide has gradually become a research hotspot. In this article, phytic acid (PA) with dual functions of doping and cross‐linking and HCl with strong ionization capacity was introduced as dopants to co‐doping polyaniline, and polyaniline hydrogel with a three‐dimensional network structure was prepared. The influence of the HCl/PA co‐doping ratio on conductive polyaniline hydrogel (CPAniH) was explored. The synthesis process and mechanism of HCl/PA‐CPAniH were analyzed and explained. In addition, the conductivity and mechanism of HCl/PA‐CPAniH, as well as the hydrogel characteristics were characterized and studied. A new electrochemical sensor based on polyaniline hydrogel and silver nanoparticles was constructed to detect hydrogen peroxide. The sensor has a good linear relationship, a wide linear range, and a high‐detection limit for H2O2. In addition, it also shows that HCl/PA‐CPAniH is a good interface material for electrochemical sensors and has a certain application potential.

Electrochemical sensors on board a Zeppelin NT: in-flight evaluation of low-cost trace gas measurements

Abstract. In this work, we used a Zeppelin NT equipped with six sensor setups, each composed of four different low-cost electrochemical sensors (ECSs) to measure nitrogen oxides (NO and NO2), carbon monoxide, and Ox (NO2+O3) in Germany. Additionally, a MIRO MGA laser absorption spectrometer was installed as a reference device for in-flight evaluation of the ECSs. We report not only the influence of temperature on the NO and NO2 sensor outputs but also find a shorter timescale (1 s) dependence of the sensors on the relative humidity gradient. To account for these dependencies, we developed a correction method that is independent of the reference instrument. After applying this correction to all individual sensors, we compare the sensor setups with each other and to the reference device. For the intercomparison of all six setups, we find good agreements with R2≥0.8 but different precisions for each sensor in the range from 1.45 to 6.32 ppb (parts per billion). The comparison to the reference device results in an R2 of 0.88 and a slope of 0.92 for NOx (NO+NO2). Furthermore, the average noise (1σ) of the NO and NO2 sensors reduces significantly from 6.25 and 7.1 to 1.95 and 3.32 ppb, respectively. Finally, we highlight the potential use of ECSs in airborne applications by identifying different pollution sources related to industrial and traffic emissions during multiple commercial and targeted Zeppelin flights in spring 2020. These results are a first milestone towards the quality-assured use of low-cost sensors in airborne settings without a reference device, e.g., on unmanned aerial vehicles (UAVs).

Thin Films of Polyaniline-Based Nanocomposites with CeO2 and WO3 Metal Oxides Applied to the Impedimetric and Capacitive Transducer Stages in Chemical Sensors.

There is a recognized need for the development of cost-effective, stable, fast, and optimized novel materials for technological applications. Substantial research has been undertaken on the role of polymeric nanocomposites in sensing applications. However, the use of PANI-based nanocomposites in impedimetric and capacitive electrochemical sensors has yet to be understood. The present study aimed to explore the relationship between the sensitivity and linearity of electrochemical pH sensors and the composition of nanocomposites. Thin films of PANI/CeO2 and PANI/WO3 were deposited via spin coating for characterization and application during the electrochemical impedance and capacitance spectroscopy (EIS and ECS) transduction stages. The findings showed that the optimized performance of the devices was extended not only to the sensitivity but also to the linearity. An increase of 213% in the ECS sensitivity of the PANI/CeO2 compared to the metal oxide and an increase of 64% in the ECS linearity of the PANI/WO3 compared to the polymeric sensitivity were reported. This study identified the structure-property relationship of nanocomposite thin films of PANI with metal oxides for use in electrochemical sensors. The developed materials could be applied in devices to be used in different fields, such as food, environment, and biomedical monitoring.

A chemically modified solid-state sensor for magnesium(ii) ions and esomeprazole magnesium potentiometric assay.

The use of electrochemical sensors offers a simple, affordable solution with great reliability. Magnesium is a mineral that the body requires to function properly. It encourages preserving a stable pulse, strong bones, and healthy blood pressure. Herein, a novel ion-selective electrode using esomeprazole magnesium trihydrate as an ion-association complex was developed for magnesium(ii) ion determination in mineral water, drug substances, and pharmaceutical formulations. The electrode response was optimized in terms of plasticizer type, ion exchanger concentration, and membrane composition. To find the best sensor combination, the initial optimization research was performed using eight different sensors. A membrane containing 20% esomeprazole magnesium trihydrate, 36% carbon, and 44% o-Nitrophenyl Octyl Ether (NPOE) as a plasticizer yielded the best potentiometric response. The developed sensor demonstrated a Nernstian response with a slope of 29.93 ± 0.1 mV per decade in the concentration range of 1.41 × 10-5 mol L-1 to 1 × 10-2 mol L-1. Within a pH range of 5-8, it had a low detection limit of 4.13 × 10-6 mol L-1. When compared to the official method, there are no statistically significant differences.

Recent Advances in Electrochemical Biosensors for Monitoring Animal Cell Function and Viability

Redox reactions in live cells are generated by involving various redox biomolecules for maintaining cell viability and functions. These qualities have been exploited in the development of clinical monitoring, diagnostic approaches, and numerous types of biosensors. Particularly, electrochemical biosensor-based live-cell detection technologies, such as electric cell-substrate impedance (ECIS), field-effect transistors (FETs), and potentiometric-based biosensors, are used for the electrochemical-based sensing of extracellular changes, genetic alterations, and redox reactions.

Various nanomaterials and cell-friendly ligands are used to enhance the sensitivity of electrochemical biosensors. Here, we discuss recent advances in the use of electrochemical sensors for determining cell viability and function, which are essential for the practical application of these sensors as tools for pharmaceutical analysis and toxicity testing. We believe that this review will motivate researchers to enhance their efforts devoted to accelerating the development of electrochemical biosensors for future applications in the pharmaceutical industry and stem cell therapeutics.

Study of the effect of protein synthesis inhibitors on growing <i>Escherichia coli</i> bacteria using electrochemical sensors

Background. The study of the mechanisms of action of antibiotics requires the integrated use of traditional microbiological and physicochemical methods. The aim. To study the response of Escherichia coli bacteria to the action of four antibiotics, inhibitors of protein synthesis, using combined approach. Methods. Bacteria were grown under aerobic conditions on minimal M9 medium with glucose. Tetracycline, kanamycin, streptomycin and chloramphenicol have been tested. The effect of antibiotics on survival (CFU) and growth rate was determined. Respiratory activity, sulfide production, extracellular potassium, as well as pH and Eh of the medium were measured using electrochemical sensors directly in a growing culture in the “real time”, membrane potential was measured using a DiBAC dye and a Leica DM2000 fluorescent microscope. Results. The tested antibiotics were divided into two groups according to their properties. Tetracycline and chloramphenicol showed a pronounced bacteriostatic effect, growth inhibition began immediately after the addition of antibiotics and occurred at a high rate. Both antibiotics inhibited respiration, stimulated sulfide production and an Eh jump. Bacteria treated with tetracycline and chloramphenicol retained the ability to maintain membrane potential and intracellular potassium better. Inhibition of respiration led to a decrease in glucose catabolism, as evidenced by a lower rate of acidification of the medium compared to the control. Growth inhibition with streptomycin and kanamycin was initiated with a 30-minute delay. Both antibiotics showed a bactericidal effect, did not stimulate sulfide production and Eh jump, did not inhibit respiration, but caused a drop in membrane potential and intracellular potassium. High respiratory activity promoted glucose catabolism, as evidenced by the rapid acidification of the medium. Of interest is the detection of kanamycin-induced sulfide production during E. coli growth on MOPS medium. Conclusion. An analysis of the data obtained indicates that the use of electrochemical sensors in combination with traditional methods is a promising approach to studying the mechanisms of action of antibiotics.

Electrochemical Digitization of Biological Fluids Samples

Digital medicine based on the integration of all medical data from a particular patient has become a reality today, thanks to information technology. Traditional medical examinations can be supplemented by assessment results of the oxidative-anti-oxidative (OAO) status of the body. Electrochemical sensors are able to not only determine the integral indicators of the OAO system of the body but also to depict details of the processes occurring in the system. The main obstacle to the widespread use of electrochemical sensors in medical diagnostics is the extremely small amount of received information in comparison to the tens of thousands of known human diseases. The problem can be eliminated only by rethinking the purpose of electrochemical measurement within the framework of thermodynamics of information processes and information theory. In the information paradigm of electrochemical analysis of biological fluids, a sample is considered an electrochemical message created by a sensor. The purpose of electrochemical measurement is to obtain information in a volume sufficient to identify the sample composition within the range of possible concentrations of its components. The fundamentals of the thermodynamics of information processes are considered and conclusions that are of practical importance for the development of electrochemical sensors and analyzers are derived. It is shown that the potentiostatic control of the sensor is physically impacted by the electromechanical instability of the electrical double layer, which is the main source of sensor signal noise. Estimates of a minimum amount of analytical signal information required for the identification of a sample of known composition, such as a biological fluid, are provided. Examples of highly informative analytical signals for flowing and stationary samples are presented. Problems related to the visualization of such signals are noted.

Electrochemical Characterization and Application of Graphene Oxide Materials Obtained By Electrochemical Exfoliation of Graphite

Graphene oxide (GO) materials possess oxygen functional groups located at the edges and at the surface of the graphitic layers, confering them dispersibility in water, biocompatibility, and high affinity for specific molecules. These properties are highly appealing for their use in electrochemical sensors. However, the density and type of functional groups and defects in these materials also influence the heterogeneous electron transfer rate of redox processes occurring at the GO-based electrodes 1,2. In this respect, it is necessary to investigate the physicochemical and electrochemical properties of GO materials to choose the most suitable one for a target application.Here, we report a simple and facile platform for the electrochemical characterization of GO materials 3. The GO sheets are self-assembled on a glassy carbon electrode (GCE) through an aminophenyl-film linker (AP) through electrostatic interaction and pi-pi stacking, Figure 1a. Then, the modified electrodes are characterized by cyclic voltammetry with 1 mM [Fe(CN)6]3-/4- redox couple to determine the electrochemical surface area (ESA) through the Randles-Sevcik equation and to calculate the standard rate constant of electron transfer (k0) by the Nicolson method.In this work, series of GO materials were obtained by electrochemical exfoliation of graphite in 0.1 M H2SO4. The electrochemical exfoliation of graphite in aqueous solution is an easy and “green” method that allows the synthesis of large amounts (in the order of grams) of materials (EGO: electrochemically exfoliated graphene oxide) with tunable composition in a short time (few hours). The applied voltage and the distance between the graphite and the counter electrodes were varied, Figure 1b, to obtain EGOs with different physicochemical properties such as the number of layers, structural defects, type and content of oxygenated groups. Transmission electron microscopy, Raman spectroscopy and X-ray photoelectron spectroscopy analysis were used to investigate the physicochemical properties of the EGOs. As shown in Figure 1c, the measured ESA and k0 scale with each other and are sensitive to the physicochemical properties of EGOs. This confirms the suitability of the proposed platform to characterize the EGO materials 3.Finally, selected EGO materials were used to fabricate electrochemical aptasensors for the detection of cocaine. The influence of the EGO physicochemical properties on the performance of the aptasensors will be presented and discussed.References(1) Kampouris, D. K.; Banks, C. E.

Detection and Treatment of Persistent Pollutants in Water: General Review of Pharmaceutical Products

AbstractEnvironmental problems of great complexity arise from the enormous number of toxic substances that are generated by anthropogenic activities. Seemingly, society encounters new issues every day thus these problems seem to be endless. Now in the face of the COVID‐19 pandemic and the SARS‐CoV‐2 crisis, a large number of emerging treatment compounds generated by pharmaceutical companies worldwide makes future issues even more treacherous. For this reason, there is an increasing need to detect and treat emerging compounds to prevent them from becoming persistent pollutants. This review describes the advances in the use of electrochemical sensors with modified carbon‐based electrodes among other issues, to determine antibiotics, anti‐inflammatories and antidepressants levels in the environment. It further explores technologies suggested for cleaning wastewater polluted by pharmaceutical products using biological or advanced oxidation processes including photolysis, photocatalysis, microwave heating, ultrasound, Fenton, electro‐Fenton, photoelectro‐Fenton and various combined treatments.

Study of the early response of Escherichia coli lpcA and ompF mutants to ciprofloxacin

In most previous studies the sensitivity of Escherichia coli outer membrane mutants to ciprofloxacin (CF) was studied by MIC method. In the present work, the early response of these mutants to CF was studied using physiological and biochemical methods and electrochemical sensors. The use of sensors made it possible to monitor dissolved oxygen, potassium and extracellular sulfide continuously directly in growing cultures in real time. In the absence of CF, no significant differences were found between the mutants deficient in porin OmpF and lipopolysaccharide (LPS) and the parent. The only exception was 5–6 times higher extracellular glutathione and 1.5–3 times lower intracellular glutathione in the lpcA compared to the parent and the ompF. Ciprofloxacin inhibited growth, respiration, membrane potential and K+ consumption, which was less pronounced in both mutants compared to the parent. Changes in these parameters correlated with each other, but not with survival. A reversible increase in sulfide level was observed at 3 μg ml−1 CF in the parent, at 20 μg ml−1 CF in ompF and was absent in lpcA at all concentrations. The data obtained show that the use of electrochemical sensors can provide a more complete understanding of the early response of bacteria to CF.

Electrochemical Impedance Spectroscopy in the Characterisation and Application of Modified Electrodes for Electrochemical Sensors and Biosensors.

Electrochemical impedance spectroscopy is finding increasing use in electrochemical sensors and biosensors, both in their characterisation, including during successive phases of sensor construction, and in application as a quantitative determination technique. Much of the published work continues to make little use of all the information that can be furnished by full physical modelling and analysis of the impedance spectra, and thus does not throw more than a superficial light on the processes occurring. Analysis is often restricted to estimating values of charge transfer resistances without interpretation and ignoring other electrical equivalent circuit components. In this article, the important basics of electrochemical impedance for electrochemical sensors and biosensors are presented, focussing on the necessary electrical circuit elements. This is followed by examples of its use in characterisation and in electroanalytical applications, at the same time demonstrating how fuller use can be made of the information obtained from complete modelling and analysis of the data in the spectra, the values of the circuit components and their physical meaning. The future outlook for electrochemical impedance in the sensing field is discussed.

The objective of this study was to evaluate the Carbon Monoxide Levels caused by the “San Juan” festival in the city of Pucallpa 2021. The methodology used was through the use of electrochemical sensors, taking 2 schedules specific diurnal (7 am to 2 pm) and night (6 pm to 1 am) in ranges per sampling point with analysis intervals of 5 seconds to obtain the average. Twelve randomly distributed points in the city of Pucallpa were analyzed, evaluated for 9 days. The results indicate that 8 out of 10 families used firewood or charcoal to cook the Juane and that 9 out of 10 families made or cooked the juane for the festival of “San Juan- Pucallpa 2021” on June 23 (one day before the festival). Likewise, the levels of Carbon Monoxide before the festival of “San Juan” were an average of 4,270 mg / m3, during an average 6,660 mg / m3 and then an average of 4,940 mg / m3 in the city of Pucallpa in the year 2021. It is concluded that the effect on the levels of Carbon Monoxide caused by the festival of "San Juan" in the city of Pucallpa in 2021, is that the National Air Quality Indices were "Good" before and after the festival, but classified as “Moderate” during this.
