Encyclopedia of novel composite electrode for probe of cyanotoxic agents, biohazards, food safety issues including sustainability and environmental challenges

Abstract

Since the last many years there has been tremendous development in field of electrochemical sensing the present review documents the recent advances in field of electrochemical sensing by using various electro analytical techniques i.e., colometric, square wave, and differential potentiometric and imperometric methods of analysis. The present content comprises of various potential applications of novel electrochemical immunosensors for probe of cyanotoxic agents, biological specimen, and environmental and toxic heavy metals i.e.Cd, Pb, Hg and CN-2compounds. This study focuses on various analytical aspects of novel electrochemical immunosensors for potential electro analytical application i.e. better selectivity, sensitivity, limit of detection and limit of quantification. Prime feature of novel nonmaterial based electrochemical immuonosensors is larger electro analytically active surface areas which provide better interaction between analyte and electrode surface resulting in better limit of detection and quantification.
