Electrodeposition of bimetallic NiAu alloy dendrites on carbon papers as highly sensitive disposable non-enzymatic glucose sensors

Abstract The bimetallic NiAu alloy dendrites were directly grown on the carbon papers using template free electrodeposition approaches, which demonstrated superior non-enzymatic glucose sensing performance. The enhanced electrochemical performance may be due to the dendrite structure and the low charge transfer resistance originating from the synergistic effect of Ni and Au.
