Extended Data Fig. 4: Selectivity of the MolEMS g-FET sensors.

Real-time ∆I_ds responses of MolEMS g-FETs carrying different probes upon targeted (5 × 10⁻¹⁶ M) and non-targeted (5 × 10⁻¹⁵ M) analytes. a, The targeted analyte is thrombin, and non-targeted analytes are Casein and BSA. b, The targeted analyte is ATP, and non-targeted analytes are CTP and GTP. c, The targeted analyte is Hg²⁺, and non-targeted analytes are Fe³⁺, Cd²⁺, Zn²⁺, Ca²⁺ and Cu²⁺. All samples were technical replicates.
