Abstract
Tenofovir (TNF) is a nucleotide reverse transcriptase inhibitor used as an antiviral medication to treat human immunodeficiency virus (HIV) and hepatitis B virus infections. The extensive use of TNF can result in its release into the environment, and there is growing interest in developing simple and cost-effective methods for detecting TNF. We report that the electrochemical dissolution of gold in a chloride ion-containing electrolyte is suppressed in the presence of TNF. The quenching of the gold electrodissolution response is the result of the adsorption of TNF onto the gold surface. A simple analysis shows that we can relate the degree of TNF surface coverage to the relative size of the quenching of the gold electrodissolution response and follow the time-dependent absorption of TNF onto the gold electrode surface.

Abstract
Tenofovir (TFV) is an antiviral drug used to treat the co-infections of HIV/HBV viruses. Accurate monitoring of TFV drug levels is essential for evaluating patient adherence, optimizing dosage, and assessing treatment efficacy. Herein, we propose an innovative electrochemical sensing approach by using the alkaline phosphatase (ALP) enzyme with the support of BaTiO3 nanoparticles. An attractive sensitivity and selectivity of the developed sensor towards TFV detection were achieved. First, the nanoparticles were synthesized by following a single-step sol-gel method and characterized through various analytical techniques, including SEM, EDX, FT-IR, BET, zeta potential, XRD, and UV-vis and Raman spectroscopy. The suggested mechanism demonstrated the formation of a strong bond between TFV and the ALP enzyme, primarily through the phosphate group, resulting in enzyme inhibition. Various parameters like nanoparticle amount, electrode modification time with enzyme and BaTiO3 nanoparticles, and drug incubation time were optimized. The biosensor demonstrated an outstanding limit of detection (LOD) of 0.09 nM and recovery percentages of 98.6-106% in human blood serum, indicating adequate repeatability and selectivity. The proposed biosensor can be converted into a portable device for measuring small sample volumes and observing patients for immediate medical care or personalized therapies. It achieved better sensitivity compared to existing methods, making it suitable for precise drug detection in microdoses.

Abstract
This article presents the results of the synthesis of Se NPs stabilized by a quaternary ammonium compound-catamine AB. Se NPs were obtained by chemical reduction in an aqueous medium. In the first stage of this study, the method of synthesis of Se NPs was optimized by a multifactorial experiment. The radius of the obtained samples was studied by dynamic light scattering, and the electrokinetic potential was studied using acoustic and electroacoustic spectrometry. Subsequently, the samples were studied by transmission electron microscopy, and the analysis of the data showed that a bimodal distribution is observed in negatively charged particles, where one fraction is represented by spheres with a diameter of 45 nm, and the second by 1 to 10 nm. In turn, positive Se NPs have a diameter of about 70 nm. In the next stage, the influence of the active acidity of the medium on the stability of Se NPs was studied. An analysis of the obtained data showed that both sols of Se NPs exhibit aggregative stability in the pH range from 2 to 6, while an increase in pH to an alkaline medium is accompanied by a loss of particle stability. Next, we studied the effect of ionic strength on the aggregative stability of Se NPs sols. It was found that negatively charged ions have a significant effect on the particle size of the positive sol of Se NPs, while the particle size of the negative sol is affected by positively charged ions.

Abstract
Tenofovir disoproxil fumarate (TDF) is an antiretroviral medication with significant curative effects, so its quantitative detection is important for human health. At present, there are few studies on the detection of TDF by electrochemical sensors. This work can be a supplement to the electrochemical detection of TDF. Moreover, bare electrodes are susceptible to pollution, and have high overvoltage and low sensitivity, so it is crucial to find a suitable electrode material. In this work, zirconium oxide (ZrO2) that has a certain selectivity to phosphoric acid groups was synthesized by a hydrothermal method with zirconyl chloride octahydrate as the precursor. A composite modified glassy carbon electrode for zirconium oxide-chitosan-multiwalled carbon nanotubes (ZrO2-CS-MWCNTs/GCE) was used for the first time to detect the TDF, and achieved rapid, sensitive detection of TDF with a detection limit of sub-micron content. The ZrO2-CS-MWCNTs composite was created using sonication of a mixture of ZrO2 and CS-MWCNTs solution. The composite was characterized using scanning electron microscopy (SEM) and cyclic voltammetry (CV). Electrochemical analysis was performed using differential pulse voltammetry (DPV). Compared with single-material electrodes, the ZrO2-CS-MWCNTs/GCE significantly improves the electrochemical sensing of TDF due to the synergistic effect of the composite. Under optimal conditions, the proposed method has achieved good results in linear range (0.3~30 μM; 30~100 μM) and detection limit (0.0625 μM). Moreover, the sensor has the merits of simple preparation, good reproducibility and good repeatability. The ZrO2-CS-MWCNTs/GCE has been applied to the determination of TDF in serum and urine, and it may be helpful for potential applications of other substances with similar structures.

Abstract
This paper discusses the electrochemical behavior of antiviral drug Tenofovir (TFV) and its possible applicability towards electroanalytical determination with diverse detection strategies using square-wave voltammetry. Namely, oxidation processes were investigated using glassy carbon electrode with graphene oxide surface modification (GO/GCE), while the reduction processes, related to the studied analyte, were analyzed at a renewable silver amalgam electrode (Hg(Ag)FE). Scanning electron microscopy imaging confirmed the successful deposition of GO at the electrode surface. Catalytic properties of graphene oxide were exposed while being compared with those of bare GCE. The resultant modification of GCE with GO enhanced the electroactive surface area by 50% in comparison to the bare one. At both electrodes, i.e., GO/GCE and Hg(Ag)FE, the TFV response was used to examine and optimize the influence of square-wave excitation parameters, i.e., square wave frequency, step potential and amplitude, and supporting electrolyte composition and its pH. Broad selectivity studies were performed with miscellaneous interfering agents influence, including ascorbic acid, selected saccharides and aminoacids, metal ions, non-opioid analgesic metamizole, non-steroidal anti-inflammatory drug omeprazole, and several drugs used along with TFV treatment. The linear concentration range for TFV determination at GO/GCE and Hg(Ag)FE was found to be 0.3–30.0 µmol L–1 and 0.5–7.0 µmol L–1, respectively. The lowest LOD was calculated for GO/GCE and was equal to 48.6 nmol L–1. The developed procedure was used to detect TFV in pharmaceutical formulations and patient urine samples and has referenced utilization in HPLC studies.

Abstract
Viruses are the main pathogenic substances that cause severe diseases in humans and other living things. They are among the most common microorganisms, and consequently, antiviral drugs have emerged to prevent and treat viral infections. Antiviral drugs are an essential drug group considering their prescription and consumption rates for different diseases and indications. Therefore, it is crucial to develop accurate and precise analytical methods to detect antiviral drugs in various matrices. Chromatographic techniques are used frequently for the quantification purpose since they allow simultaneous determination of antivirals. Electrochemical methods have also gained importance since the analysis can be performed quickly without the need for pretreatment. Spectrophotometric and spectrofluorimetric methods are used because they are simple, inexpensive, and less time-consuming methods. The purpose of this review is to present an overview of the analysis of currently used antiviral drugs from 2010 to 2021. Since studies on antiviral drugs are numerous, selected publications were reviewed in this article. The analysis of antiviral drugs was divided into three main groups: chromatographic, spectrometric, and electrochemical methods which were applied to different matrices, including pharmaceutical, biological, and environmental samples.

Abstract
A rapid, simple, and highly sensitive electroanalytical method was developed for the first time for the detection of ultra-trace amounts of nilotinib in sodium lauryl sulphate media. The electrochemical behavior of nilotinib was investigated on a glassy carbon electrode in the absence and presence of sodium lauryl sulphate media by cyclic voltammetry and adsorptive stripping voltammetric methods. The cyclic voltammograms proved that the electrochemical behavior of nilotinib showed irreversible and diffusion-adsorption-controlled oxidation processes in 0.1 M H2SO4. The effect of surfactant concentration on the first and second peaks of nilotinib was examined. Depending on whether the surfactants had a monomer or monolayer hemimicelle structure, they were attracted to amine moieties at related points in the nilotinib structure through the electrostatic interaction. The sensitivity of the method was markedly enhanced in the presence of surfactants using adsorptive stripping square-wave voltammetry. Under optimum conditions, nilotinib was determined in a concentration range of 2.0 × 10-8 to 2.0 × 10-6 mol L-1, with a limit of detection of 6.33 × 10-9 mol L-1 in 0.1 M H2SO4 containing 2.0 × 10-7 mol L-1 sodium lauryl sulphate. The proposed method can be applied for the sensitive determination of nilotinib in biological samples. Graphical abstract.

Abstract
Background:
This review investigates the ophthalmic drugs that have been studied with
voltammetry in the web of science database in the last 10 years.
Introduction:
Ophthalmic drugs are used in the diagnosis, evaluation and treatment of various ophthalmological
diseases and conditions. A significant literature has emerged in recent years that investigates
determination of these active compounds via electroanalytical methods, particularly voltammetry. Low
cost, rapid determination, high availability, efficient sensitivity and simple application make voltammetry
one of the most used methods for determining various kinds of drugs including ophthalmic ones.
Methods:
In this particular review, we searched the literature via the web of science database for ophthalmic
drugs which are investigated with voltammetric techniques using the keywords of voltammetry,
electrochemistry, determination and electroanalytical methods.
Results:
We found 33 types of pharmaceuticals in nearly 140 articles. We grouped them clinically into
seven major groups as antibiotics, antivirals, non-steroidal anti-inflammatory drugs, anti-glaucomatous
drugs, steroidal drugs, local anesthetics and miscellaneous. Voltammetric techniques, electrodes, optimum
pHs, peak potentials, limit of detection values, limit of quantification values, linearity ranges,
sample type and interference effects were compared.
Conclusion:
Ophthalmic drugs are widely used in the clinic and it is important to determine trace
amounts of these species analytically. Voltammetry is a preferred method for its ease of use, high sensitivity,
low cost, and high availability for the determination of ophthalmic drugs as well as many other
medical drugs. The low limits of detection values indicate that voltammetry is quite sufficient for determining
ophthalmic drugs in many media such as human serum, urine and ophthalmic eye drops.

Abstract
Infectious diseases are caused from pathogens, which need a reliable and fast diagnosis. Today, expert personnel and centralized laboratories are needed to afford much time in diagnosing diseases caused from pathogens. Recent progress in electrochemical studies shows that biosensors are very simple, accurate, precise, and cheap at virus detection, for which researchers find great interest in this field. The clinical levels of these pathogens can be easily analyzed with proposed biosensors. Their working principle is based on affinity between antibody and antigen in body fluids. The progress still continues on these biosensors for accurate, rapid, reliable sensors in future.
