Switchable wetting and flexible SiC thin film with nanostructures for microfluidic surface-enhanced Raman scattering sensors.

Highlights: [•] Flexible surface-nanostructured SiC film with switchable wetting behavior is presented. [•] The contact angle of super-hydrophobic SiC nano-ball surface achieves to higher than 160°. [•] The contact angle of super-hydrophilic SiC nano-tip surface reduces to below 1°. [•] The switchable wettability was systematically investigated from both physical and chemical mechanisms. [•] The first experimental demonstration of SiC-based surface-enhanced Raman scattering materials is presented. [ABSTRACT FROM AUTHOR]
