Design of intrinsically disordered proteins that undergo phase transitions with lower critical solution temperatures

APL Materials, 2021
Many naturally occurring elastomers are intrinsically disordered proteins (IDPs) built up of repeating units, and they can demonstrate two types of thermoresponsive phase behavior.

Tuning the Size of Thermoresponsive Poly(N-Isopropyl Acrylamide) Grafted Silica Microgels

Gels, 2017
Core-shell microgels were synthesized via a free radical emulsion polymerization of thermoresponsive poly-(N-isopropyl acrylamide), pNipam, on the surface of silica nanoparticles. Pure pNipam microgels have a lower critical solution temperature (LCST) of
