A Novel Bio-Inspired Ag/3D-TiO<sub>2</sub>/Si SERS Substrate with Ordered Moth-like Structure
This paper reports a novel method to fabricate a bio-inspired SERS substrate with low reflectivity, ultra-sensitivity, excellent uniformity, and recyclability. First, double layers of polystyrene spheres with different particle sizes were assembled on the surface of a silicon wafer to act as a moth-...
