A highly sensitive and ecofriendly assay platform for the simultaneous electrochemical determination of rifampicin and isoniazid in human serum and pharmaceutical formulations

Abstract

Simple fabrication of an electrochemical sensor for simultaneous determination of rifampicin and isoniazid based on electrochemical modification of SPCE surface with reduced graphene oxide and nickel hydroxide film (Ni(OH)2/rGO/SPCE) without using toxic chemical agents.

Non-Enzymatic Electrochemical Sensors for Accurate and Accessible Uric Acid Detection

“…The increase in oxidation peak current with an increase in the scan rate from 10-100 mV s −1 in a standard redox solution along with the oxidation peak potential shifting to slightly higher values confirm the diffusion limiting process. 28,29 The electrochemical UA sensing measurements are performed using CV in a standard redox solution at a scan rate of 100 mV s −1 and pH 7.4. CV scans of NIP and MIP sensors toward various concentrations of UA ranging from 1-500 μM are shown in Fig.…”

“…Linearity in the increase in I pa with ascending values of the scan rate square root (n 1/2 ) is mathematically expressed, conrming our premise that this process is diffusionlimited. 38,39 The results of the linear regression analysis for different sensors are given as follows:…”
