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 glucose and interfering species. Multiple nanoporous Pt films with similar roughness factors were easily fabricated using this method, which showed good enough and similar performance to other reported glucose sensors, suggesting a simple and quality controlled manufacturing method for nanoporous Pt films as nonenzymatic glucose sensors.

This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
