Description/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.
