Fig. S2 (a) Amperometric responses of Cu NWs/Ti electrodes in 1 mM glucose at
different stages with the addition of 0.1 mM fructose, 0.1 mM saccharose, 0.1 mM
DA, 0.1 mM AA, 0.1 mM UA, in the solution of 0.1 M NaOH at an applied potential
of 0.70 V vs. Ag/AgCl/sat’d KCl. (b) Amperometric responses of an electrode on the
addition of 0.2 mM glucose solution for respective five times. (c) Amperometric
responses of five electrodes prepared with the same method on the addition of 0.2
mM glucose solution. (d) The curve of response current varying with the storing time
of the Cu NWAs/Ti electrodes in air at room temperature.
