Abstract
Independent optical control of microfluidic valves (see Figure) formed from optomechanically responsive nanocomposite hydrogels is achieved using strongly absorbing Au nanoparticles or nanoshells embedded within a thermally responsive polymer. Valves formed from composites with different nanoparticles could be independently controlled by changing the illumination wavelength.Keywords
