Abstract
Gold nanocrystals are dispersed uniformly in poly(dimethylsiloxane) to produce a plasmonic composite. The composite can be readily used to fabricate microfluidic channels. An efficient optical heating approach on the microfluidic chips made of the composite is realized on the basis of plasmon-enabled photothermal conversion. A fluid flow switch based on the plasmonic heating is also demonstrated.
