Abstract:

Electrochemical sensors have become one of the important development directions for the rapid detection of biosensing on the basis of their fast response, strong specificity and high accuracy, but it is currently difficult to achieve the detection level of single biomolecules, mainly originating from the key probe materials. Single-atom materials featuring their simple and well-defined atomic localized structures have received extensive attention in the field of electrochemical biosensing due to a unified active site rivaling biological enzymes. Herein, the synthesis of single-atom materials with a homogeneous local coordination environment and their applications in electrochemical biosensing are reviewed. Moreover, the challenges and opportunities of single-atom materials in electrochemical biosensing are furtherly outlooked.

Key words: Single-atom material, Local coordination structure, Electrochemical biosensing, Health monitoring
