Electrochemical Biosensors with Silver Nanoparticles as Signal Labels
Cai‐Xia Yu, Fan Xiong, Lei‐Lei Liu
Abstract
The fabrication of electrochemical biosensors with high sensitivity and selectivity has attracted increasing attention during the past decades. Due to their excellent chemical and electrical properties, especially low-redox potential and highly characteristic solid-state Ag/AgCl process, silver nanoparticles (AgNPs) have been extensively employed to design novel and efficient electrochemical sensing methods. Herein, we summarize the applications of AgNPs as electroactive labels in biosensors. This review aims to provide a snapshot of recent development of AgNPs-based electrochemical sensors and to illustrate their benefits for biological and biomedical applications.
