Electrochemical Sensors Using Two‐Dimensional Layered Nanomaterials

Two‐dimensional (2D) layered nanomaterials, e.g. graphene and molybdenum disulfide (MoS 2 ), have rapidly emerged in material sciences due to their unique physical, chemical and mechanical properties. In the meanwhile, there is a growing interest in constructing electrochemical sensors for a wide range of chemical and biological molecules by using these 2D nanomaterials. In this review, we summarize recent advances on using graphene and MoS 2 for the development of electrochemical sensors for small molecules, proteins, nucleic acids and cells detection. We also provide our perspectives in this rapidly developing field.
