Altered electrochemistry of amiloride drug on boron-doped diamond electrode: Rapid and selective detection in urine by square-wave cathodic stripping voltammetry for application in doping control

Effect of Lipid Composition on the Inhibition Mechanism of Amiloride on Alamethicin Ion Channels in Supported Phospholipid Bilayers

“…Amiloride has redox properties, which are used for electroanalytical detection of this compound in various solutions. , Figure S2 shows the cyclic voltammograms (CVs) of the β-Tg-modified gold (111) surface in pure 0.1 M NaF and in the presence of 25 μM amiloride. A flat background is observed in the absence of amiloride; however, when amiloride is present, an oxidation peak at 0.18 V versus Ag/AgCl and a corresponding reduction peak at ∼0.02 V versus Ag/AgCl due to the redox properties of amiloride.…”

Electrochemical detection of mephedrone using a graphene screen-printed electrode: a new sensitive and selective approach to identify synthetic cathinones in forensic analysis

“…In this sense, due to an increased surface area and high electron transfer rate in screen-printed working electrodes based on conductive graphene inks (SPE-GP), these sensors have been used to improve the sensitivity of many electroanalytical methods, 38–40 including for application in forensic analysis, 41 but never hitherto for MEP. Moreover, to improve the sensitivity for electrochemical detection, the adsorptive stripping voltammetry (AdSV) technique has been reported for many applications, 42 such as in doping control 43,44 or forensic analysis. 21,33 The AdSV technique consists of two steps: (1) pre-accumulation of the analyte on the working electrode surface, which is due to an adsorption process (physical or chemical); (2) electrochemical detection of oxidation or reduction of the accumulated analyte on the electrode surface, which is commonly performed using a pulsed voltammetric technique, such as adsorptive stripping differential pulse voltammetry (AdSDPV).…”

Using a Boron‐Doped Diamond Electrode in Anionic Surfactant Media as an Improved Electrochemical Sensor for the Anticancer Drug Ibrutinib

“…[25] The pretreatment process can be used to increase the sensitivity and electron transfer of a sensor, reduce the effect of fouling, and provide good repeatability. [26][27][28] Substances that tend to accumulate on a surface or interface are known as surfactants. Surfactants have the ability to adsorb at the interface between bulk phases such as air and water, oil and water, or electrode and solution.…”
