Nanoporous platinum thin films synthesized by electrochemical dealloying for nonenzymatic glucose detection
Abstract
Nanoporous Pt thin films were prepared by simultaneous deposition of Pt and Si and subsequent dealloying of Si out of the PtxSi1−x films. The x values were easily controlled in the range of 0.10 to 0.90 by the distances between the sample position and the target positions and by the plasma power for the targets. With a roughness factor of around 40, the nanoporous Pt films showed enough sensitivity, selectivity, and detection limit for
