Electrochemical Immunoassays Based on Graphene: A Review

Immunoassay is a common analytic method with great practicability. Recently, there is a growing interest in applying graphene to modern biosensor research due to its distinct physical and chemical properties, such as excellent conductivity, high surface area, ease of functionalization, and so on. In this review, we summarized the recent researches on the development of electrochemical immunoassays based on graphene. We focus on the different roles of graphene in constructing various electrochemical immunosensors and provide a perspective about this research field.
