Fig. 4: Detection of E-cadherin at different protein levels and with different amount of cells.

a DPV detection of varying concentrations (1–900 ng mL−1) of purified E-cadherin protein. b Calibration curve showing the linear relationship of the biosensor in detection of E-cadherin. c DPV detection of varying amount of A549 cells. d Measurement of the stability of the biosensor for detecting E-cadherin. Current responses were obtained using the initial E-cad-QD probe and the probe stored for 1 month. Error bars represent ± s.d. (n = 3). Source data are provided as a Source Data file.
