Method & Evidence

AimTo develop an electroanalysis strategy for the selective detection of glutathione (GSH) in biological samples using melamine-copper (MA-Cu) nanocomposites.

MethodExperimental research and development of an electrochemical sensing platform.

ProcedureMelamine-copper (MA-Cu) nanocomposites were synthesized with varying ratios of melamine to copper, leading to different morphologies. Electrodes were modified with rod-like MA-Cu nanocomposites. The electrochemical response of solid-state CuCl was measured at low potential. The displacement reaction between CuCl and GSH was studied, where GSH selectively displaces CuCl, leading to a decrease in the electrochemical signal. The detection range for GSH was determined, and the strategy was validated using extractions from Hela and yeast cells.
