We report a facile and new method to tune the electron transport (ETp) band gaps of proteins (bovine serum albumin, BSA) via doping with other molecules (cyanocobalamin, Vb12). The results indicated that doping with Vb12 can enhance the ETp ability of BSA and reduce its conduction band (CB) and valence band (VB) energy levels, thereby achieving the goal of tuning protein ETp band gaps.
