An electrochemical sensor was fabricated for the rapid and simple detection of enrofloxacin (EF). Modification screen-printed gold electrodes (SPE) with molecularly imprinted polymers (MIPs) allowed by square wave voltammetry (SWV), measuring oxidation peak at +0.9 V. The principle is based on formation binding sites affinities specificities comparable those natural antibodies. showed a linear ...

Ajwain is one of the medicinal plants, which the highest composition is thymol, as a strong antioxidant respect to the obtained chromatograms of GC/MS. The antioxidant activity of the Ajwain is measured by square wave voltammetry method and cyclic voltammetry method and 2, 2-Diphenyl-1-picrylhydrazyl (DPPH) method in at the specific concentrations of 1%, 1.5%, 2% and 2.5% and constant pH. The r...

Pseudomonas Aeruginosa (P. Aeruginosa) is a prevalent and opportunistic bacterium which frequently causes severe nosocomial infection. Current clinical detection methods are limited in terms of necessary time equipment. Increasingly, P. Aeruginosa’s electrochemically active virulence factor pyocyanin has facilitated its rapid detection, primarily through voltammetric such as cyclic voltammetry ...

Here, we report on the use of electrochemical methods for the detection of volatiles fatty acids (VFAs), namely acetic acid. We used tetra-tert-butyl phthalocyanine (PcH₂-tBu) as the sensing material and investigated its electroanalytical properties by means of cyclic voltammetry (CV) and square wave voltammetry (SWV). To realize the electrochemical sensing system, the PcH₂-tBu has been dropcas...

A novel electrochemical sensor for testosterone detection has been prepared by the chemical modification of a gold electrode (AuE). For modification, specific polyurethane (PU) films were synthesized from hexamethylene diisocyanate, olivetol, polyethylene glycol-100 (PEG100) and β-cyclodextrin. The PUs investigated as selective films, used to coat AuE surface at different concentrations thickne...

This study investigates the effects of boron concentration on boron-doped diamond (BDD) electrodes for electrochemical sensors ciprofloxacin. The concentration, scan rate, and pH BDD with concentrations 0.1, 0.5, 1% were examined to determine optimal conditions. Furthermore, square wave voltammetry (SWV) in phosphate buffer 7 was used analyze behavior results revealed a linear calibration curve...

Multiwalled carbon nanotubes were used to modify the surface of a glassy carbon electrode to enhance its electroactivity. Nafion served to immobilise the carbon nanotubes on the electrode surface. The modified electrode was used to develop an analytical method for the analysis of ascorbic acid (AA) by square-wave voltammetry (SWV). The oxidation of ascorbic acid at the modified glassy carbon el...
