Abstract
O-GO QD-modified electrode. Under optimum conditions, the developed PEC biosensing platform exhibited good analytical performance with a linear range of 50-10 000 fM thrombin and a limit of detection of 29 fM. Impressively, our strategy offers a new horizon in developing bridge-connected graphene-coated nanomaterials and novel signal amplification strategy for the development of PEC biosensors.
