Chiral properties were investigated in Cu and Cu2O composite films prepared by magneto-electrodeposition. The Cu-Cu2O films were electrodeposited in a CuSO4 and Na2SO4 aqueous solution under magnetic fields B (2 and 5 T) parallel (+B) or antiparallel (-B) to the faradaic current. The magneto-electrodeposited films were used as modified electrodes, and the chiral voltammetric behaviors were observed as follows. The 2T-film electrodes of Cu-Cu2O(15%) showed the oxidation current difference between D- and L-glucoses. The voltammograms of L-DOPA (3-(3,4-dihydroxyphenyl)alanine) showed the peak potential difference between the +5T-film and -5T-film electrodes of Cu-Cu2O(40%).
