General description

N-Isopropylacrylamide (NIPAM) is a biocompatible monomeric unit that can be used in the formation of stimuli responsive polymers due to its temperature sensitive properties. These properties include temperature based volumetric and phase changes, which change when the temperature of the solution reaches a lower critical solution temperature (LCST).

Application

NIPAM can be used to prepare poly(NIPAM) for a variety of applications such as tissue engineering, cell culture, biomedical coating, drug delivery, and muscle regeneration.
