Abstract

A new approach to the targeted thermally activated transport of chemical agents and physiologically active compounds is reported. The method involves the immobilization of these compounds on a water-soluble polymer with a low critical solution temperature and heating the delivery site above the critical temperature. The approach was illustrated with trypsin immobilized on N-isopropylacrylamide-acrylamide- N-acryloylphthalimide ternary copoly mers.
