Photo-responsive Soft Actuators Based on Spiropyran Functionalised Hydrogels

Publication Type: 
Refereed Conference Meeting Proceeding
Abstract: 
Integrating stimuli-responsive materials into micro-fluidic systems could provide external control over fluid flow and reduce the over-all complexity of the device. In this study photo-actuator hydrogels were generated using a N-isopropylacrylamide-co-acrylated spiropyran-co-acrylic acid (p(NIPAAM-co-SP-co-AA) copolymer. These hydrogels have the ability to contract upon exposure to white light and reswell in the dark. It was shown that the photo-actuation is successfully reversible in a relatively short time period (seconds to minutes). The hydrogels were then incorporated in microfluidic devices as micro-valves for photocontrol of flow.
