Figure 4From: DNA-templated synthesis of PtAu bimetallic nanoparticle/graphene nanocomposites and their application in glucose biosensorCyclic voltammograms of GOD/PtAuNP/ss-DNA/GR modified electrode. They are in (curve a) N2-saturated and O2-saturated PBS (pH 7.0) in the (curve b) absence and (curve c) presence of 1.0 mM glucose at 100 mV s-1.Back to article page
