“…Next attention was turned to study the effect of solution pH on the electrochemical oxidation of LDP using CV in the pH range of 2.0–8.0. Figure indicates that the peak potentials were shifted towards less positive potentials with an increase in pH from 2.0–8.0, most likely due to the protonation‐deprotonation properties of LDP .…”

A simple and efficient procedure is described for the electrochemical determination of ledipasvir (LDP) in presence of co‐formulated drug sofosbuvir (SOF). Herein, a highly sensitive, low‐cost electrochemical protocol was utilized to fabricate a zeolite modified carbon paste electrode (ZY/CPE) through mixing of zeolite nanostructures with graphite powder. The fabricated sensor displayed high sensitivity, allowing optimal charge transfer/electrode kinetics. Different experimental and chemical factors, including electrode composition, effect of pH, scan rate and amount of ZY were evaluated carefully to obtain the highest electrochemical response. Under optimized conditions and using square wave voltammetry (SWV), the current response of the ZY/CPE electrochemical sensing platform exhibited a detection limit of 7.5×10−9 M and a large linear range from 5.0×10−8 to 1.0×10−4 M. The practical applicability of the suggested electrochemical platform was verified in the assessment of LDP in pharmaceutical formulations with excellent recoveries in the range of 99.50–98.87 %. Moreover, a biological relevance of the developed sensor was established by the analysis of LDP in human urine and plasma samples with satisfactory recoveries of 99.00 and 99.68 %, respectively. Due to the simplicity and ease of preparation of the proposed sensor, it can be used in quality control laboratories and for clinical analysis.

Vitamins are a chemically heterogeneous group of compounds known as essential for the normal functioning of the organic metabolism. Their decrease in humans can lead to several diseases and not being produced by the body, they need to be obtained from dietary sources or supplements. For these reasons, their determination in food, pharmaceutical and clinical samples is crucial. This article reviews key advances in electrochemical measurements of vitamins over the past decade. Particular attention is given to papers proving applicability to real samples analysis. The technical features of the proposed sensors are presented and discussed along with their analytical performances. Future trends and challenges are also addressed.

“…The effect of solution pH on the electrochemical oxidation of TRH was studied using cyclic voltammetry in the range of 6.0‐10.0. Figure shows the peak potentials were shifted towards less positive potentials with an increase in pH from 6.0 to 10.0 which is attributed to the protonation–deprotonation properties of TRH .…”

Novel insights into the strategy of highly precise, carbon‐based electrochemical sensors are presented by exploring the excellent properties of graphene oxide (GO) and multiwalled carbon nanotube composites (GO‐MWCNTs/CPE) for the sensitive determination of tramadol hydrochloride (TRH). Cyclic voltammetry, differential pulse voltammetry, chronoamperometry (CA), and electrochemical impedance spectroscopy (EIS) scanning electron microscopy, and X‐ray diffraction (XRD) techniques were used to characterize the properties of the sensor. The linear response obtained for TRH using the GO‐MWCNTs/CPE was found to be over the range of 2.0x10−9 to 1.1x10−3 M with a good linearity and high correlation (0.9996). The limits of detection and quantification were found to be 1.50x10−10 M and 4.99 x 10−10 M, respectively. The proposed sensor was applied for determination of TRH in the presence of presence of co‐formulated drugs ketorolac tromethamine (KTM) and paracetamol (PAR). The sensor was shown to successfully apply to the determination of TRH in plasma as real samples. Satisfactory recoveries of TRH from samples clearly revealed that the proposed sensor can be applied into clinical analysis, quality control and a routine determination of drugs in pharmaceutical formulations.
