Designing Temperature and pH Sensitive NIPAM Based Polymers

Poly(N-isopropylacrylamide), or PNIPAM, is a stimuli-responsive polymer that responds to changes in pH and temperature and has a LCST around 32 C.

Poly(N-isopropylacrylamide)-based Smart Surfaces for Cell Sheet Tissue Engineering

Tissue engineering has become a key therapeutic tool in the treatment of damaged or diseased organs and tissues, such as blood vessels and urinary bladders.
