a CV response study of GCE electrode (curve a), SnS2/GCE electrode (curve b), C-Mab/SnS2/GCE electrode (curve c), BSA/C-Mab/SnS2/GCE electrode (curve d). b EIS response study of the GCE, SnS2/GCE, C-Mab/SnS2/GCE, and BSA/C-Mab/SnS2/GCE electrodes. Inset: the corresponding equivalent circuit. c Increased magnitude of oxidation response current of BSA/C-Mab/SnS2/GCE electrode with increased scan rate from 10 mV/s to 100 mV/s. d The current magnitude increased with increasing scan rate. e CV studies of BSA/C-Mab/SnS2/GCE electrode as a function of cortisol concentration varying from 100 pM to 100 μM. f Linearity curve for the current response with different cortisol concentrations. g DPV studies of BSA/C-Mab/SnS2/GCE electrode as a function of cortisol concentration varying from 100 pM to 100 μM. h Linearity curve for the current response with different cortisol concentrations
