Sharp-cornered liquid drops by wetting of nanoscale features
Sharp-cornered liquid drops by wetting of nanoscale features
Serrated-edge droplets: The wetting of metallic microstructures with nanoscale features, used as substrates for surface-enhanced Raman scattering, can result in sharp bending of the droplet edges. Tethering of the liquid/air/substrate contact line induces flows of analyte to particular locations as the droplet recedes during evaporation (see SEM image). Molecules are preferentially deposited in the pyramidal pits on these structures.

Abstract
Serrated-edge droplets: The wetting of metallic microstructures with nanoscale features, used as substrates for surface-enhanced Raman scattering, can result in sharp bending of the droplet edges. Tethering of the liquid/air/substrate contact line induces flows of analyte to particular locations as the droplet recedes during evaporation (see SEM image). Molecules are preferentially deposited in the pyramidal pits on these structures.
