The strategy of planting designed antifouling peptides in conducting polymers offered an effective way to develop electrochemical sensors for practical biomarkers assaying in complex biological samples.In this study we developed a uniform, large-area, layered graphene composite of graphene oxide/graphene (GO/G) for the detection of circulating miRNA-21, a reliable biomarker for early cancer diagnosis. We prepared this layered composite of GO/G through low-damage plasma treatment of bilayer G. The top layer of G was oxidized (i.e., ato
