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.
