Pump up the volume : Poly( N ‐isopropylacrylamide) gel containing poly(2‐(methacryloyloxy)decyl phosphate) surfactant (NIPA‐PMDP gel) shows a rapid reversible volume decrease above its phase‐transition temperature. The gel also undergoes an abrupt volume change on laser irradiation, which results in expulsion of a stream of water (see pictures). The gel can be used in fluid control systems, such as drug delivery.
