Delivering nanoparticles and molecules to the same spot with a superhydrophobic bulls-eye for surface-enhanced Raman scattering

Abstract

We present a superhydrophobic silicon bulls-eye. Water droplets remain centered as they dry, enabling delivery of nanoparticles or molecules to the center. SERS spectra of molecules (R6G) at very low concentrations (10<sup>-15</sup> M) are demonstrated.
