We report the detection of non-enzyme electrochemical glucose using nanoporous gold (NPG) as electrodes. The free-standing
NPG films showed a robust and sensitive current response to glucose. The effects of pore sizes, detecting potentials and chloride ions
on glucose oxidation were systematically investigated. NPG with a smaller pore size possesses higher sensitivity. In addition, the
NPG electrodes can effectively avoid interference from the oxidation of common organic interferents in body liquids. The high sensitivity
and selectivity make NPG promising electrodes for applications in electrochemical biosensors.
