Aptamer-free upconversion nanoparticle/silk biosensor system for low-cost and highly sensitive detection of antibiotic residues. Biosens Bioelectron 2024; 258:116335.

Abstract
The detection of antibiotics is crucial for safeguarding the environment, ensuring food safety, and promoting human health. However, developing a rapid, convenient, low-cost, and sensitive method for antibiotic detection presents significant challenges. Herein, an aptamer-free biosensor was successfully constructed using upconversion nanoparticles (UCNPs) coated with silk fibroin (SF), based on Förster resonance energy transfer (FRET) and the charge-transfer effect, for detecting roxithromycin (RXM). A synergistic FRET efficiency was achieved by utilizing alizarin red and RXM complexes as energy acceptors, with UCNP as the energy donor, and immobilizing an ultrathin SF protein corona within 10 nm. The biosensor detects RXM in deionized water with high sensitivity primarily through monolayer adsorption, with a detection range of 1.0 nM-141.6 nM and a detection limit as low as 0.68 nM. The performance of this biosensor was compared with the ultra-performance liquid chromatography-mass spectrometry (UPLC-MS/MS) method for detecting antibiotics in river water separately and a strong correlation between the two methods was observed. The biosensor exhibited long-term stability in aqueous solutions (up to 60 d) with no attenuation of fluorescence intensity. Furthermore, the biosensor's applicability extended to the highly sensitive detection of other antibiotics, such as azithromycin. This study introduces a low-cost, eco-friendly, and highly sensitive method for antibiotic detection, with broad potential for future applications in environmental, healthcare, and food-related fields.

ENVIRONMENTAL RESEARCH 2024; 252:119048. [PMID: 38697595 DOI: 10.1016/j.envres.2024.119048] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/13/2024] [Revised: 04/15/2024] [Accepted: 04/28/2024] [Indexed: 05/05/2024]
Abstract
Adsorption is considered an interesting option for removing antibiotics from the environment because of its simple design, low cost, and potential efficiency. In this work we evaluated three by-products (pine bark, oak ash, and mussel shell) as bio-adsorbents for the antibiotic azithromycin (AZM). Furthermore, they were added at doses of 48 t ha-1 to four different soils, then comparing AZM removal for soils with and without bio-adsorbents. Batch-type experiments were used, adding AZM concentrations between 2.5 and 600 μmol L-1 to the different bio-adsorbents and soil + bio-adsorbent mixtures. Regarding the bio-adsorbents, oak ash showed the best adsorption scores (9600 μmol kg-1, meaning >80% retention), followed by pine bark (8280 μmol kg-1, 69%) and mussel shell (between 3000 and 6000 μmol kg-1, 25-50% retention). Adsorption data were adjusted to different models (Linear, Freundlich and Langmuir), showing that just mussel shell presented an acceptable fitting to the Freundlich equation, while pine bark and oak ash did not present a good adjustment to any of the three models. Regarding desorption, the values were always below the detection limit, indicating a rather irreversible adsorption of AZM onto these three by-products. Furthermore, the results showed that when the lowest concentrations of AZM were added to the not amended soils they adsorbed 100% of the antibiotic, whereas when the highest concentrations of AZM were spread, the adsorption decreased to 55%. However, when any of the three bio-adsorbents was added to the soils, AZM adsorption reached 100% for all the antibiotic concentrations used. Desorption was null in all cases for both soils with and without bio-adsorbents. These results, corresponding to an investigation carried out for the first time for the antibiotic AZM, can be seen as relevant in the search of low-cost alternative treatments to face environmental pollution caused by this emerging contaminant.

Abstract
Clarithromycin is a very important macrolide antibiotic used to treat bacterial infections in human and veterinary medicine. This study reports the development and validation of cost-effective, simple, precise, accurate, and robust high-performance liquid chromatography (HPLC) for the determination of clarithromycin (CLA) in tablets. Reversed-phase chromatography was conducted using a standard column at 55°C with ultraviolet detection at 215 nm. A mobile phase consisting of acetonitrile -2-methyl-2-propanol -potassium phosphate buffer was used at a flow rate of 1.0 mL/min. The proposed method displayed good linearity, precision, accuracy, robustness, and specificity. The present HPLC was compared with capillary electrophoresis and bioassay methods and the results indicated that there was no significant difference between these methods. Moreover, the obtained results demonstrated the validity of the isocratic HPLC, which allows reliable quantitation of CLA in pharmaceutical samples. Thus, it can be used as a substitute alternative methodology for the routine quality control of this medicine, in situations where other methods are less accessible in the laboratory.

Abstract
In this work, a cyclic voltammetry analysis for the detection of Ascorbic Acid (AA) based on a carbon-clay paste electrode modified with titanium dioxide (CPEA/TiO2) is presented. The electrochemical sensor was prepared using clay and carbon graphite, mixed with TiO2 to investigate the electrode behavior towards the detection of AA. Comprehensive characterization approaches including X-ray diffraction (XRD), Selected area electron diffraction (SAED), Transmission electron microscopy (TEM), Fourier transform infra-red spectroscopy (FTIR) were carried out on different samples. The results indicated that, the electrode has been effectively modified, while the electrochemical parameters of AA on CPEA/TiO2/UV such as the charge transfer coefficient (α a ), number of electrons (n) transferred and standard potential were calculated. CPEA/TiO2/UV exhibit better photoactivity and also higher electronic conductivity under light radiation (100 W). The linear range for AA was determined between 0.150μM and 0.850 μM with the straight-line equation equivalent to I p a ( μ A ) = 2.244 [ A A ] + 1.234 (n = 8, R2 = 0.993). The limit of detection was 0.732 μM (3σ) and limit of quantification was 2.440 μM. For the analytical applications, pharmaceutical tablets such as Chloroquine phosphate, Azithromycin and Hydroxychloroquine sulfate were performed. In addition, interference study in the analytical application was performed, and it was found that the electroanalytical method used can be well adopted for simultaneous electrochemical detection of AA and Azithromycin.

Abstract
An electrochemical cell containing two graphite rods was filled with the appropriate electrolyte (0.2 M ammonia + 0.2 M ammonium sulphate) and connected to the exfoliation system to synthesize graphene (EGr). A bias of 7 V was applied between the anode and cathode for 3 h. After synthesis, the morphology and structure of the sample was characterized by SEM, XRD, and FTIR techniques. The material was deposited onto the surface of a glassy carbon (GC) electrode (EGr/GC) and employed for the electrochemical detection of azithromycin (AZT). The DPV signals recorded in pH 5 acetate containing 6 × 10-5 M AZT revealed significant differences between the GC and EGr/GC electrodes. For EGr/GC, the oxidation peak was higher and appeared at lower potential (+1.12 V) compared with that of bare GC (+1.35 V). The linear range for AZT obtained with the EGr/GC electrode was very wide, 10-8-10-5 M, the sensitivity was 0.68 A/M, and the detection limit was 3.03 × 10-9 M. It is important to mention that the sensitivity of EGr/GC was three times higher than that of bare GC (0.23 A/M), proving the advantages of using graphene-modified electrodes in the electrochemical detection of AZT.

Abstract
Azithromycin (AM) detection has become of great interest as being one of the prescribed medicines in the medication protocol in Egypt for the recent COVID-19 pandemic. Herein, a carbon paste electrode (CPE) was simply amended with fumed silica (FS) for determining AM. The characterization of the new material was done by different techniques including scanning electron microscopy (SEM), transmission electron microscopy (TEM) and electrochemical impedance spectroscopy (EIS). The newly modified fumed silica carbon paste electrode (FSCPE) exhibited a highly sensitive response towards the oxidation of 1.0 mM AM in phosphate buffer solution (PBS) for a pH range of 5.0 - 10.0. The effect of varying AM concentrations was studied in PBS of pH 7.4 with a detection limit of 11 µM and a quantification limit of 37 µM. Eventually, the recently amended electrode attained reasonable sensitivity and constancy for AM detection in actual trials like blood plasma and pharmaceutical drugs.

Abstract
At the beginning of the COVID-19 outbreak (end 2019 - 2020), therapeutic treatments based on approved drugs have been the fastest approaches to combat the new coronavirus pandemic. Nowadays several vaccines are available. However, the worldwide vaccination program is going to take a long time and its success will depend on the vaccine public's acceptance. Therefore, outside of vaccination, the repurposing of existing antiviral, anti-inflammatory and other types of drugs, have been considered an alternative medical strategy for the COVI-19 infection. Due to the broad clinical potential of the drugs, but also to their possible side effects, analytical methods are needed to monitor the drug concentrations in biological fluids and pharmaceutical products. This review deals with analytical methods developed in the period 2015 - July 2021 to detect potential drugs that, according to a literature survey, have been taken into consideration for the treatment of COVID-19. The drugs considered here have been selected on the basis of the number of articles published in the period January 2020-July 2021, using the combination of the keywords: COVID-19 and drugs or SARS-CoV-2 and drugs. A section is also devoted to monoclonal antibodies. Over the period considered, the analytical methods have been employed in a variety of real samples, such as body fluids (plasma, blood and urine), pharmaceutical products, environmental matrices and food.

Abstract
Our screening data revealed the threat macrolide antibiotics, especially azithromycin (AZN), posed to human health with its increasing occurrence in water environment. The electrochemical sensor based on molecularly imprinted polymer (MIP) is a promising platform that caters for the next generation of intelligent wastewater treatment plants (WWTPs) by virtue of its wide tolerance to water from all sources and in-situ monitoring. However, low initiation potentials of cross-linking monomers contributed by the electron-rich circumstance allowed them to usurp sites designed for functional monomers when electrically stimulated, leading to an unsatisfactory binding capacity. Another uncertainty is that multiple reaction sites of cross-linking monomers granted them complex polymerization routes and made it difficult to ensure the consistency of preparation. Serval monomers had been investigated with electrochemical tools and the performance of sensors constructed with these monomers were compared in this study. Based on the results, we proposed a protocol in which a novel functional monomer possessing a stronger electron-donating group, phenyl, was adopted to compete for the dominance in electropolymerization. Beyond that, the cross-linking monomer was modified with electron-withdrawing groups to raise its initiation potential. A monothiophene with a moderate initiation potential was also recruited as the linker to address the steric hindrance. In this way, polymerization proceeded in a specific order. It is worth mentioning that the Marangoni flow is an ideal tool to deal with the Coffee-ring deposition while drop-casting. The resulting sensor showed good performance with a limitation of detection (LOD) of 0.120 μM for AZN and a satisfactory selectivity, and the design can be applied to constructing sensors for a variety of macrolide antibiotics.

Abstract
In this research paper, an innovative electrochemical sensor was suggested for simultaneous voltammetric analysis of azithromycin (AZM) and hydroxychloroquine (HCQ) for the first time. The sensor based on hydrothermal synthesis of vanadium disulfide quantum dots (VS2 QDs) and insertion within 3D N, S graphene aerogel (3D N, S @ GNA) and carbon nanotubes nanaostructure as a new and widely group of carbon nanomaterials. The nanocomposites were characterized morphologically using different techniques. In addition, the nanomaterials were characterized electrochemically using cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and differential pulse voltammetry (DPV). The proposed electrochemical sensor showed wide dynamic linear ranges of 0.28–30 × 10−8 M and 0.84–22.5 × 10−8 M for analysis of AZM and HCQ, respectively. The limits of detection (LODs) based on signal to noise (S/N) 3:1 were found to be 0.091 × 10−8 M and 0.277 × 10−8 M for AZM and HCQ, respectively. Briefly, the electrochemical sensor had good stability, selectivity, reproducibility and feasibility for simultaneous detection of AZM and HCQ in presence of different interfering species.

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
Background:
Macrolide antibiotics are known as versatile broad-spectrum antibiotics.
Macrolides belong to the oldest group of antibacterial agents. The macrolides which are frequently
used for clinical purposes are broadly categorized in three classes depending on the number of
membered macrocyclic lactone ring. These three classes actually consist of 14, 15 or 16 atoms in macrocyclic
lactone ring which are linked through glycosidic bonds. Erythromycin, azithromycin clarithromycin
and roxithromycin are frequently used to control against bacterial infections.
Methods:
The quality assurance and quality controls are important tasks in the pharmaceutical industries.
Consequently, to check the quality of drugs, there is a strong need to know about alternative
analytical methods for the routine analysis. Many methods have been reported in the literature for the
quantitative determination of erythromycin, clarithromycin, azithromycin and clarithromycin in
pharmaceutical formulations and biological samples.
Results:
This review will cover a brief introduction of erythromycin, azithromycin, clarithromycin and
roxithromycin as well as analytical techniques for their assessment. Each developed method has its
own merits and demerits.
Conclusion:
Any accurate method could be used for the quality control and quality assurance of
macrolide antibiotics according to the availability, performance and procedure of selected instrument
as well as skill and expertise of the analyst.

Abstract
Background:
Electroanalytical techniques play a very important role in the areas of medicinal,
clinical as well as pharmaceutical research. Amongst these techniques, the voltammetric methods
for the determination of drugs using nanomaterials based chemically modified electrodes (CMEs)
have received enormous attention in recent years. This is due to the sensitivity and selectivity they
provide on qualitative as well as quantitative aspects of the electroactive analyte under study. The aim
of the present review was to discuss the work on nanomaterials based CMEs for the analysis of drugs
covering the period from 2000 to present employing various voltammetric techniques for different
classes of the drugs.
Methods:
The present review deals with the determination of different classes of drugs including analgesics,
anthelmentic, anti-TB, cardiovascular, antipsychotics and anti-allergic, antibiotic and gastrointestinal
drugs. Also, a special section is devoted for enantioanalysis of certain chiral drugs using
voltammetry. The detailed information of the voltammetric determination for the drugs from each
class employing various techniques such as differential pulse voltammetry, cyclic voltammetry, linear
sweep voltammetry, square wave voltammetry, stripping voltammetry, etc. are presented in tabular
form below the description of each class in the review.
Results:
Various nanomaterials including carbon nanotubes, graphene, carbon nanofibers, quantum
dots, metal/metal oxide nanoparticles, polymer based nanocomposites have been used by researchers
for the development of CMEs over a period of time. The large surface area to volume ratio, high conductivity,
electrocatalytic activity and biocompatibility make them ideal modifiers where they produce
synergistic effect which helps in trace level determination of pharmaceutical, biomedical and medicinal
compounds. In addition, macrocyclic compounds as chiral selectors have been used for the determination
of enantiomeric drugs where one of the isomers captured in the cavities of chiral selector
shows stronger binding interaction for one of the enantiomorphs.
Conclusion:
arious kinds of functional nanocomposites have led to the manipulation of peak potential
due to drug - nanoparticles interaction at the modified electrode surface. This has facilitated the
simultaneous determination of drugs with almost similar peak potentials. Also, it leads to the enhancement
in voltammetric response of the analytes. It is expected that such modified electrodes can
be easily miniaturized and used as portable, wearable and user friendly devices. This will pave a way
for in-vivo onsite real monitoring of single as well as multi component pharmaceutical compounds.

Abstract
In this paper, a simple and effective method for the determination of six macrolide antibiotics (MACs), including tylosin, tilmicosin, azithromycin, clarithromycin, roxithromycin, and kitasamycin, in the chicken sample using liquid chromatography-tandem mass spectrometry (LC-MS/MS) was developed based on a self-built porous aromatic framework- (PAF-) based solid phase sorbent. The main parameters influencing the extraction efficiency, such as sorbent amounts, type of the eluent, pH of the sample, and the eluent volume, were evaluated. Under the optimized condition, the limits of detection were from 0.2 to 0.5 μg·kg-1. The recoveries of the method ranged from 82.1% to 101.4% with the relative standard deviations less than 11.1%. All the results demonstrated that the established method is potential for the determination of macrolide antibiotics in food safety analysis and monitoring.

Abstract
The performances of two FAU-type zeolites with different SiO2/Al2O3 ratios were evaluated for the removal of antibiotics of three different classes, namely azithromycin, ofloxacin, and sulfamethoxazole, from aqueous solutions. Commercial zeolites were used, without any previous treatment. Use of a small adsorbent dosage resulted in fast antibiotic adsorption that followed pseudo-second order kinetics. The removals of azithromycin and sulfamethoxazole were highly pH-dependent, with low removal percentages observed under acid (pH 2.5-4.5) and basic (pH 8.5-10.5) conditions, respectively. The Freundlich isotherm model provided the best fits to the adsorption data. The adsorption mechanisms appeared to involve both electrostatic and H-bonding interactions. Using an antibiotics mixture, percentage removals of azithromycin and ofloxacin onto the zeolites of up to 79% were obtained. Both materials presented good adsorption (>50%) of azithromycin and ofloxacin from a real sample of effluent wastewater. The results showed that zeolites with FAU structure can be used as effective adsorbents for the removal of antibiotics with different physicochemical properties, including molecules with large volumes, such as azithromycin.

Abstract
A simple and non-destructive FTIR method was used to determine certain proton pump inhibitors (PPIs) in binary and ternary mixtures. Proton pump inhibitors (PPIs); omeprazole (OMZ), esomeprazole (EZM), lansoprazole (LAN), pantoprazole sodium (PAN sodium) and rabeprazole sodium (RAB sodium) in binary mixture with domperidone (DOM) and ternary mixture of OMZ, clarithromycin (CLM) and tinidazole (TNZ) were determined in the solid-state by FTIR spectroscopy for the first time. The method was validated according to ICH-guidelines where linearity was ranged from 20 to 850μg/g and 20-360μg/g for PPIs and DOM, respectively in binary mixtures and 10-400, 100-8000 and 150-14,000μg/g for OMZ, CLM and TNZ, respectively. Limits of detection were found to be 6-100 and 9-100μg/g for PPIs and DOM, respectively and 4, 40 and 50μg/g for OMZ, CLM and TNZ, respectively. The method was applied successfully for determination of the cited drugs in their respective pharmaceutical dosage forms.

Abstract
A simple and effective method of miniaturized solid-phase extraction (mini-SPE) was developed for the simultaneous purification and enrichment of macrolide antibiotics (MACs) (i.e. azithromycin, clarithromycin, erythromycin, lincomycin and roxithromycin) from honey and skim milk. Mesoporous MCM-41 silica was synthesized and used as sorbent in mini-SPE. Several key parameters affecting the performance of mini-SPE procedure were thoroughly investigated, including sorbent materials, amount of sorbent and elution solvents. Under the optimized condition, satisfactory linearity (r2 > 0.99), acceptable precision (RSDs, 0.3-7.1%), high sensitivity (limit of detection in the range of 0.01-0.76 μg/kg), and good recoveries (83.21-105.34%) were obtained. With distinct advantages of simplicity, reliability and minimal sample requirement, the proposed mini-SPE procedure coupled with ultrahigh performance liquid chromatography and quadrupole time-of-flight tandem mass spectrometry could become an alternative tool to analyze the residues of MACs in complex food matrixes.
