(A) Cyclic voltammograms of the (GOx/pDAB)-PB/AuNP/TiNTs based electrode (curve a and b), and (GOx/Au/pDAB)-PB/AuNP/TiNTs based electrode (curve c and d) in absence (curve a and c) and presence (curve b and d) of 10 mM glucose in PBS (pH 6.0).(B) Effect of pH on the response of the (GOx/pDAB)-PB/AuNP/TiNTs (curve a) and (GOx/Au/pDAB)-PB/AuNP/TiNTs (curve b) based electrode to 10 mM glucose; inset shows the effect of pH on reduction peak current of the PB/AuNP/TiNTs electrode. Amperometric response of (C) (GOx/pDAB)-PB/AuNP/TiNTs electrode and (D) (GOx/Au/pDAB)-PB/AuNP/TiNTs electrode (a) in the absence and (b–j) successive addition of glucose at −0.35 V; inset shows the linear calibration plot.
