Integration of a recyclable silver substrate for in situ surface-enhanced Raman spectroscopy in digital microfluidics.

Published in: Chemical communications (Cambridge, England) (2024)

We report a new chip-integrated recyclable SERS substrate, achieved by photochemical deposition of silver nanoparticles onto titanium dioxide (TiO 2 ) thin film. Facilitated by the photocatalytic activity of titanium dioxide the SERS substrate can be recycled for multiple analysis. This enables quasi-real time detection of various compounds in an automated and reusable DMF-SERS platform.
