Stimuli-responsive (smart) microgels are micron sized polymer particles that change shape in response to enviornmental stimuli. This responsiveness makes them useful in the fields of drug delivery, catalysis, sensing, and photonics. The most commonly used smart microgel material is poly(N-isopropylacrylamide) (pNIPAAm) because it has a lower critical solution temperature (LCST) around 32°C. Both the LCST and Tg of (pNIPAAm) are readily tunable by changing its composition or its particle geometry. As such controlling each of these aspects independently is critical to optimizing the characteristics of the microgel.
