“…Various supported catalysts have been used but only few works are devoted to natural phosphate as a support . However, solid phosphates such as natural phosphate, hydroxyapatite and fluorapatite have been prepared and used as catalysts . Recently, we reported an efficient method for the preparation of β‐enaminoesters using hydroxyapatite as catalyst…”

We report the preparation of palladium nanoparticles supported on mesoporous natural phosphate (Pd@NP) using a wetness impregnation method. The prepared catalyst was characterized using various techniques. Furthermore, the reduction and preparation of the palladium nanoparticles was followed using UV–visible spectra. Based on the Scherrer equation, the crystallite size of the as‐synthesized palladium nanoparticles was 10.88 nm. The performance of the synthesized catalyst was investigated in the reduction of 4‐nitrophenol as a model substrate to 4‐aminophenol using NaBH4 as a hydrogen source. Moreover, catalytic reduction of various nitroarenes was studied and monitored using UV–visible spectroscopy and gas chromatography. The Pd@NP catalyst showed a high activity for the selected reaction and could be recycled.

Cysteine monolayer has been assembled onto bare gold electrode (SAM/Au), and subsequently deoxyribonucleic acid (DNA) has been successfully immobilized at the SAM/Au electrode. The thus modified electrode is assigned DNA/SAM/Au. Modification steps of the electrode were followed electrochemically using K4[Fe(CN6)] electrochemical marker. Also, the build‐up of the modified electrode composition is followed using EDX and the crystallographic orientation is inspected using XRD. The electrochemical behavior of paracetamol (PC) at DNA/SAM/Au electrode is investigated. Interestingly, the sluggish irreversible behavior of PC at the bare gold electrode is converted to a quasi‐reversible one at DNA/SAM/Au electrode pointing to some interaction between the immobilized DNA and PC. The enhanced electrochemical behavior of PC at modified DNA/SAM/Au electrode is successfully used for a sensitive electrochemical determination of PC. Square wave voltammetry (SWV) was used for this purpose. The concentration of PC was in linear relation with the peak current at the optimum conditions within the range 10.0–110.0 μg mL−1 with correlation coefficient (R2) of 0.998. Also, the standard deviation (SD) and relative standard deviation (RSD) were calculated and found to be 0.817 and 1.52, respectively, indicating the significance of the present method.

“…The electrochemical behavior of drugs has been studied using cyclic voltammetry, chronocoulometry, electrochemical impedance spectroscopy and differential pulse voltammetry. [33][34][35][36] Electrochemical measurements are generally carried out in a medium consisting of an electrolyte support, the choice of which is mainly dictated by the solubility of the analyte and its redox activity, such as electrical conductivity, electrochemical activity and chemical reactivity. For this purpose, the carrier electrolyte must not react with the analyte (or products) and must not undergo electrochemical reactions.…”

Current Trends in Analytical Methods for the Determination of Hydroxychloroquine and Its Application as Treatment for COVID‐19

Hydroxychloroquine (HCQ) is a drug indicated in rheumatology for the treatment of rheumatoid arthritis and systemic lupus erythematosus for its anti‐inflammatory and immunomodulatory properties. Many countries such as Morocco have recommended the use of HCQ for the treatment of COVID‐19 infection. This medication is responsible for severe acute poisoning. Therefore, Hospital laboratories have a fundamental role in affirming the diagnosis and assessing the severity of intoxication by measuring HCQ, carried out in the urine and preferably in whole blood. The analytical techniques used are essentially chromatographic. Unfortunately, these reference methods for forensic analyzes are difficult to adapt to emergency due to their delay in reporting results.
