Carbon supported olivine type phosphate framework: a promising electrocatalyst for sensitive detection of dopamine

Abstract

In this study, layered olivine-type LiMnPO4/functionalized-multiwall carbon nanotubes composite is used as an electrochemically active material for the real-time detection of dopamine and extended for the detection of human serum (E48) and rat brain-serum (C7) samples.

Selective Electrochemical Sensing Platform Based on the Synergy between Carbon Black and Single-Crystalline Bismuth Sulfide for Rapid Analysis of Antipyretic Drugs

“…Figure E shows the various pHs of redox peak current responses on the modified electrode, and the results revealed that pH 7 is more favorable for APAP detection. In addition, the linear fitting of E pa and E pc vs different pHs revealed slope values of −0.0468 V/pH (oxidation) and −0.0503 V/pH (reduction) (Figure F), which are close to the actual imaginary value of −0.059 V/pH. , Hence, the optimal pH (pH 7) of 0.05 M PB would be suitable for further electrochemical analyses.…”
