ABSTRACT
Herein, we propose a facile fabrication procedure for platinum (Pt) nanoprobes. Our approach consists in performing a one-step electrochemical etching using a mixture of DI water, acetone, and CaCl2. Our technique is self-terminated and thus does not necessitate a cut-off circuit nor other sophisticated equipment or set-up commonly used in the fabrication process of Pt nanoprobes. The Pt nanoprobes thereby manufactured demonstrate small tip radii, a high aspect-ratio, no detectable surface contamination, and good reproducibility.
