Independent optical control of two valves at a junction within a microfluidic device formed from a optomechanically responsive nanocomposite hydrogels was analyzed. Nanocomposite-hydrogel valves were formed by photopolymerizing the monomer mixture, with the inclusion of the appropriate nanoparticles, within a microfluidic device at a T-junction. It was shown that the lower critical solution temperature (LCST) of the temperature-responsive material could be tailored by altering the copolymer composition. By raising the LCST, one could also use absorbing materials with slightly overlapping absorption curves, since slight heating in non-targeted valve materials would not result in a phase change, allowing the valve to remain close.
