(188cc) NiO2, Pt, and Cu Surface Modifications of a Glassy Carbon Electrode for Electrocatalysis of Amino Acids
AIChE Annual Meeting
Monday, October 29, 2018 - 3:30pm to 5:00pm
Discussed herein are the surface modifications of a glassy carbon electrode with platinum, platinum-copper hexacyanoferrate hybrid, and nickel(IV) oxide surfaces through electrodeposition and passivation. The sensors were tested through detection of arginine, alanine, serine, and valine at physiological pH by cyclic voltammetry in a flow cell. We will report on the found sensitivity towards arginine, alanine, serine, and valine. In addition, the stability of the surfaces was also investigated. The sensitivity and stability of both sensor modification, towards amino acid detection, will be compared.
