Abstract
The present teaching relates to photo-responsive hydrogels comprising a copolymer comprising N-isopropylacrylamide (NIPAM), a polymerisable derivative of benzospiropyran, a cross-linking agent and an acid, the acid having a pKa of less than 6, wherein the hydrogel is operably responsive to exposure to water so as to undergo spontaneous protonation and swelling. The photo-responsive hydrogels described can be used in the field of microfluidic platforms.
