Characterization of the compound-graphene complex and sensor selectivity. Raman spectra of (a) nano-graphene (nG) and (b) nG complexed with ZBW1; (c) UV-vis spectra of nG, ZBW1 and the complex; (d) Selectivity of ZBW1- decorated graphene electrode for different proteins including the N-acetyl glucosamine-selective wheat germ agglutinin (WGA), the galactose-selective peanut agglutinin (PNA), bovine serum albumin (BSA) and pepsin (Pep) determined by electrochemical impedance spectroscopy. The original EIS spectra are shown in Additional file 1: Figure S5.
