Abstract
In this report, Azithromycin (Azi) antibiotic was measured by carbon paste electrode (CPE) improved by graphene nanoribbon-CoFe2O4@NiO nanocomposite and 1-hexyl-3 methylimidazolium hexafluorophosphate (HMIM PF6) as an ionic liquid binder. The electrochemical behavior of Azi on the graphene nanoribbon-CoFe2O4@NiO/HMIM PF6/CPE is investigated by voltammetric methods, and the results showed that the modifiers improve the conductivity and electrochemical activity of the CPE. According to obtained data, the electrochemical behavior of Azi is related to pH. under optimum conditions, the sensor has linear ranges from 10 µM to 2 mM with a LOD of 0.66 µM. The effect of scan rate and chronoamperometry were studied, which showed that the Azi electro-oxidation is diffusion controlled with the diffusion coefficient of 9.22 × 10-6 cm2/s. The reproducibility (3.15%), repeatability (2.5%), selectivity, and stability (for 30 days) tests were investigated, which results were acceptable. The actual sample analysis confirmed that the proposed sensor is an appropriate electrochemical tool for Azi determination in urine and Azi capsule.

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
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:
The determination of drugs in pharmaceutical formulations and human biologic fluids is
important for pharmaceutical and medical sciences. Successful analysis requires low sensitivity, high selectivity
and minimum interference effects. Current analytical methods can detect drugs at very low levels but these methods
require long sample preparation steps, extraction prior to analysis, highly trained technical staff and high-cost
instruments. Biosensors offer several advantages such as short analysis time, high sensitivity, real-time analysis,
low-cost instruments, and short pretreatment steps over traditional techniques. Biosensors allow quantification not
only of the active component in pharmaceutical formulations, but also the degradation products and metabolites in
biological fluids. The present review gives comprehensive information on the application of biosensors for drug
discovery and analysis. Moreover, this review focuses on the fabrication of these biosensors.
Methods:
Biosensors can be classified as the utilized bioreceptor and the signal transduction mechanism. The classification
based on signal transductions includes electrochemical optical, thermal or acoustic. Electrochemical and
optic transducers are mostly utilized transducers used for drug analysis. There are many biological recognition elements,
such as enzymes, antibodies, cells that have been used in fabricating of biosensors. Aptamers and antibodies
are the most widely used recognition elements for the screening of the drugs. Electrochemical sensors and biosensors
have several advantages such as low detection limits, a wide linear response range, good stability and reproducibility.
Optical biosensors have several advantages such as direct, real-time and label-free detection of many
biological and chemical substances, high specificity, sensitivity, small size and low cost. Modified electrodes enhance
sensitivity of the electrodes to develop a new biosensor with desired features. Chemically modified electrodes
have gained attention in drug analysis owing to low background current, wide potential window range, simple
surface renewal, low detection limit and low cost. Modified electrodes produced by modifying of a solid surface
electrode via different materials (carbonaceous materials, metal nanoparticles, polymer, biomolecules) immobilization.
Recent advances in nanotechnology offer opportunities to design and construct biosensors. Unique features
of nanomaterials provide many advantages in the fabrication of biosensors. Nanomaterials have controllable
chemical structures, large surface to volume ratios, functional groups on their surface. To develop proteininorganic
hybrid nanomaterials, four preparation methods have been used. These methods are immobilization, conjugation,
crosslinking and self-assembly. In the present manuscript, applications of different biosensors, fabricated
by using several materials, for drug analysis are reviewed. The biosensing strategies are investigated and discussed
in detail.
Results:
Several analytical techniques such as chromatography, spectroscopy, radiometry, immunoassays and electrochemistry
have been used for drug analysis and quantification. Methods based on chromatography require timeconsuming
procedure, long sample-preparation steps, expensive instruments and trained staff. Compared to chromatographic
methods, immunoassays have simple protocols and lower cost. Electrochemical measurements have
many advantages over traditional chemical analyses and give information about drug quantity, metabolic fate of
drugs, and pharmacological activity. Moreover, the electroanalytical methods are useful to determine drugs sensitively
and selectivity. Additionally, these methods decrease analysis cost and require low-cost instruments and
simple sample pretreatment steps.
Conclusion:
In recent years, drug analyses are performed using traditional techniques. These techniques have a
good detection limit, but they have some limitations such as long analysis time, expensive device and experienced
personnel requirement. Increased demand for practical and low-cost analytical techniques biosensor has gained interest
for drug determinations in medical sciences. Biosensors are unique and successful devices when compared to
traditional techniques. For drug determination, different electrode modification materials and different biorecognition
elements are used for biosensor construction. Several biosensor construction strategies have been developed to
enhance the biosensor performance. With the considerable progress in electrode surface modification, promotes the
selectivity of the biosensor, decreases the production cost and provides miniaturization. In the next years, advances
in technology will provide low cost, sensitive, selective biosensors for drug analysis in drug formulations and biological
samples.

Abstract
A new selective and sensitive sensor based on molecularly imprinted polymer/acetylene black (MIP/AB) was developed for the determination of azithromycin (AZM) in pharmaceuticals and biological samples. The MIP of AZM was synthesized by precipitation polymerization. MIP and AB were then respectively introduced as selective and sensitive elements for the preparation of MIP/AB-modified carbon paste (MIP/ABP) electrode. The performance of the obtained sensor was estimated by cyclic voltammetry (CV) and differential pulse voltammetry (DPV) techniques. Compared with non-molecularly imprinted polymer (NIP) electrodes, NIP/ABP electrodes, and MIP-modified carbon paste electrodes, MIP/ABP electrode exhibited excellent current response toward AZM. The prepared sensor also exhibited good selectivity for AZM in comparison with structurally similar compounds. The effect of electrode composition, extraction parameters, and electrolyte conditions on the current response of the sensor was investigated. Under the optimized conditions, the prepared sensor showed two dynamic linear ranges of 1.0 × 10−7 mol L−1 to 2.0 × 10−6 mol L−1 and 2.0 × 10−6 mol L−1 to 2.0 × 10−5 mol L−1, with a limit of detection of 1.1 × 10−8 mol L−1. These predominant properties ensured that the sensor exhibits excellent reliability for detecting AZM in pharmaceuticals and biological fluids without the assistance of any separation techniques. The results were validated by the high-performance liquid chromatography–tandem mass spectrometry method.

Abstract
A new automated pharmacoanalytical technique for convenient quantification of redox-active antibiotics has been established by combining the benefits of a carbon nanotube (CNT) sensor modification with electrocatalytic activity for analyte detection with the merits of a robotic electrochemical device that is capable of sequential nonmanual sample measurements in 24-well microtiter plates. Norfloxacin (NFX) and ciprofloxacin (CFX), two standard fluoroquinolone antibiotics, were used in automated calibration measurements by differential pulse voltammetry (DPV) and accomplished were linear ranges of 1–10 μM and 2–100 μM for NFX and CFX, respectively. The lowest detectable levels were estimated to be 0.3±0.1 μM (n=7) for NFX and 1.6±0.1 μM (n=7) for CFX. In standard solutions or tablet samples of known content, both analytes could be quantified with the robotic DPV microtiter plate assay, with recoveries within ±4% of 100%. And recoveries were as good when NFX was evaluated in human serum samples with added NFX. The use of simple instrumentation, convenience in execution, and high effectiveness in analyte quantitation suggest the merger between automated microtiter plate voltammetry and CNT-supported electrochemical drug detection as a novel methodology for antibiotic testing in pharmaceutical and clinical research and quality control laboratories.

Abstract
The surface of a glassy carbon (GC) electrode was modified with reduced graphene oxide (rGO) to evaluate the electrochemical response of the modified GC electrodes to hydrogen peroxide (H₂O₂) and hydrazine. The electrode potential of the GC electrode was repeatedly scanned from -1.5 to 0.6 V in an aqueous dispersion of graphene oxide (GO) to deposit rGO on the surface of the GC electrode. The surface morphology of the modified GC electrode was characterized by scanning electron microscopy (SEM) and atomic force microscopy (AFM). SEM and AFM observations revealed that aggregated rGO was deposited on the GC electrode, forming a rather rough surface. The rGO-modified electrodes exhibited significantly higher responses in redox reactions of H₂O₂ as compared with the response of an unmodified GC electrode. In addition, the electrocatalytic activity of the rGO-modified electrode to hydrazine oxidation was also higher than that of the unmodified GC electrode. The response of the rGO-modified electrode was rationalized based on the higher catalytic activity of rGO to the redox reactions of H₂O₂ and hydrazine. The results suggest that rGO-modified electrodes are useful for constructing electrochemical sensors.
