摘要

•Faradaic impedimetric for detecting C-RP by Au-interdigitated microelectrode.•Enhanced by AuNP-decorated molybdenum disulfide nanosheet via chemical linkers.•Modified surfaces were evidenced by high-resolution images (SEM, AFM).•5 µm microelectrode gap size detected C-RP as low as 1 fg/ml and LOD 0.01 fg/ml.•Sensing system is suitable for cellular milieu with serum containing samples.
