“…EIS has been known as one of the most powerful methods to characterize the surface property of electrodes. The Nyquist plot in EIS measurement normally includes a semicircular portion at high frequency region indicating the limited process of electrons transfer and the diameter of semicircle is equal to the electron transfer resistance (R et ) [43], whereas a linear portion at low frequency relating to the existence of Warburg diffusion resistance [44]. For this reason, EIS was employed in this work to investigate the changes in impedance of the electrodes surfaces.…”

Over the past years, the development of electrochemical sensing platforms for the sensitive detection of drug molecules have received great interests. In this research study, we introduced cauliflower‐like platinum particles decorated reduced graphene oxide modified glassy carbon electrode (Pt−RGO/GCE) as an electrochemical sensing platform for highly sensitive determination of acetaminophen (ACTM). The sensor was prepared via a simple and environmentally friendly two‐step electrodeposition method at room temperature. The combination of conductive RGO nanosheets and unique structured Pt particles (average 232 nm in diameter) provided an efficient interface with large effective surface area which greatly facilitated the electron transfer of ACTM. The experimental conditions that might affect the drug detection were studied in detail and optimized for best performance. The Pt−RGO/GCE was able to detect ACTM up to the limit of 2.2 nM with a linear concentration range from 0.01 to 350 μM. With its high reproducibility, excellent stability and selectivity, the as‐fabricated sensor was successfully applied to the ACTM content measurement in commercial tablets.

et al. 2020

In this study an impedimetric immunosensor was developed in order to determine ciprofloxacin (CIP) in wastewater samples, an emergent contaminant widely found in wastewater. To achieve this, an anticiprofloxacin antibody was immobilized on the surface of a printed carbon electrode. Then, the developed immunosensor was applied in wastewater samples from Université Laval residences (Québec, Canada) through the load transfer resistance (R ct ) using [Fe(CN) 6 ] 3À/4À as a redox probe, and the average CIP concentration was found to be 2.90 Â 10 À4 mg mL À1 . The observed R ct changes presented a linear relationship from CIP concentrations of 10 À5 to 1.0 mg mL À1 , with detection and quantification limits of 2.50 Â 10 À6 and 7.90 Â 10 À6 mg mL À1 , respectively. The immunosensor presented high selectivity and repeatability, as well as a good recovery rate in wastewater samples (97%). Significant interference with other compounds was not observed. The proposed method requires only 30 mL of sample without the use of organic solvents or preceding sample preparation and/or extraction techniques. Moreover, the method is fast: only 20 min of incubation followed by 2 min of analysis time was sufficient to obtain the CIP concentration. The method's estimated cost is U$ 2.00 per sample.

The Electrochemical Resolution of Ciprofloxacin, Riboflavin and Estriol Using Anionic Surfactant and Polymer‐Modified Carbon Paste Electrode

2019

View full text Add to dashboard Cite

In the current study, a novel electrode was prepared by utilizing electropolymerization as well as immobilization technique for the resolution of antibacterial drug Ciprofloxacin (CFX). Cyclic voltammetric (CV) technique was adopted to explore the properties of poly(Evans blue) sodium dodecyl sulphate doubly modified carbon paste electrode (PEBSDSMCPE). A significant enhancement in the electrochemical activity was observed at modified electrode compared to bare carbon paste electrode (BCPE). The effect of variation in sweep rate was also performed to evaluate the total number of electrons transferred during the oxidation of CFX. The mass transfer process taking place at the electrode surface was also examined and it was found to be controlled by diffusion phenomena. Under optimized circumstances the limit of detection (LOD) and quantification limit (LOQ) were achieved to be 1.83×10−7 M and 6.11×10−7 M respectively. PEBSDSMCPE was successfully utilized for the selective determination of CFX, Riboflavin (RFL) and Estriol (EST). The current proposed method was well adopted for the analysis of real sample.
