Sensitive electrochemical detection of bisphenol A at screen-printed graphite electrode modified with nitrogen-doped graphene sheets

“…Different materials and methods can be used to modify the surface of the working electrode to enhance the electro-activity and sensitivity of the modified electrode [21][22][23][24][25][26]. The sensing materials based on nano-materials are usually used due to their high electrical conductivity, high thermal conductivity, and unique chemical and mechanical properties [27][28][29][30][31][32][33].…”

Electrochemical sensing platform for simultaneous detection of 6-mercaptopurine and 6-thioguanine using RGO-Cu2O/Fe2O3 modified screen-printed graphite electrode

“…Nevertheless, there are some shortcomings for electrochemical sensitivity, such as huge overpotential, slow electrochemical behavior in detecting different analytes, which might be eliminated using approaches like electrode surface modification to improve interfacial electron transfer in the electroanalysis [28][29][30][31][32][33]. The electrochemical sensors can benefit from such nano-materials due to cost-effectiveness, large specific surface area, variable morphologies, excellent electrocatalytic properties, and the ability to enhance electron transfer at low overpotentials [34][35][36][37][38][39][40].…”
