6. For the electrodes preparation of electrochemical biosensors (in Fig. Q6), aniline (AN), consisting of a phenyl group attached to an amino group, and m-amino-benzenesulfonic acid (MSAN) were dissolved in water at 57 mM (each) to prepare AN:MSAN mole ratio 1:1, and various concentrations (0-0.5 wt%) of 17β-estradiol (E2, template) were added. Electropolymerization was performed by immersing screen-printed electrodes (4 mm diameter) in the AN:MSAN mixture, with or without template molecules (for 17β-estradiol- and non-imprinted electrodes, respectively) and with various concentrations of the two dimensional doping materials (e.g. tungsten disulfide, 0-0.5 wt%). Then, a potentiostat, the electronic hardware, was connected to the three electrodes and cyclic potential (−0.6 to 0.6 V vs Ag/AgCl at a scan rate of 0.1 V/s) was applied for 20 cycles.
