(a) Investigation of different antigen incubation time on GPC-1 biosensor. (b) Modified self-assembled monolayer system (3-MPA & DTT) based GPC-1 biosensor (Biosensor 1) on DPV measurements of multiple concentrations of GPC-1 antigen in undiluted human serum. (c) SAMSA modified antibody based GPC-1 biosensor (Biosensor 2) on DPV measurements of multiple concentrations of GPC-1 antigen in undiluted human serum. (d) The calibration curve based on Biosensor 1 and Biosensor 2. (e) Exhibition of change of current response at different concentrations of GPC-1 antigens based on two different biosensors. (f) Interference study based on HE4 antigen.
