a Response currents of the Au NEA/GO x electrode to injection of glucose into a stirred phosphate buffer (pH 6.9) at 0.60 V. Final concentrations: (a) 5 × 10−6 M (b) 1 × 10−5 M (c) 2 × 10−5 M, (d) 1 × 10−4 M, (e) 4 × 10−4 M, (f) 8 × 10−4 M, (g) 1 × 10−3 M, (h) 2 × 10−3 M, (i) 4 × 10−3 M, (j) 8 × 10−3 M, (k) 1 × 10−2 M. Inset shows a magnification of the first three additions of glucose. (S/N = 3).b Calibration curve of the GOD modified gold NEA toward glucose
