A novel electrochemical sensor based on an Fe–N–C/AuNP nanohybrid for rapid and sensitive gallic acid detection

Abstract

An Fe–N–C/AuNP nanohybrid was combined with a glassy carbon electrode to construct a novel electrochemical sensor for rapid detection of gallic acid (GA). The sensor exhibited excellent performance to detect GA with a wide linear response range and low detection limit.

Target-Induced Electrochemical Sensor Based on Foldable Aptamer and MoS2@MWCNTs–PEI for Enhanced Detection of AFB1 in Peanuts

“…AuNPs can effectively amplify the electrochemical performance due to their excellent electrocatalytic activity. 36 AuNPs were introduced into biosensors to immobilize the aptamers. 37 AuNPs and MoS 2 @MWCNTs−PEI demonstrate the two components' combined performance with increased specific surface area, better conductivity, and improved catalytic activity.…”
