Electrochemical mercury biosensors based on advanced nanomaterials

Abstract

Mercury ion (Hg2+) is a typical heavy metal ion to show the strong toxicity and easy accumulation in human bodies, which has been a severe pollution source in the ecological system. The detection of trace Hg2+ is always a research hotspot in developing the accurate and sensitive electrochemical biosensor. Recently, more and more novel nanomaterials have been successfully designed to confirm remarkable advantages on the Hg2+ recognition due to their high electrocatalysis, specific surface area, conductivity and etc. This review aims to present the latest progress on advanced nanomaterials for the electrochemical Hg2+ detection. Emphasis will be given to the main detection mechanisms and nanostructure control methodology of these nanomaterials. Meanwhile, the performance of various nanomaterials-based mercury biosensors will be compared to discuss the positive effects on the detection performance from different nanostructures. This article is expected to provide an inspiration on the design of novel nanomaterials to construct high-performance electrochemical mercury biosensors.
