Architecture and composition influence on the properties of some smart polymeric materials designed as matrices in drug delivery systems. A comparative study

This new class of interpolymeric complexes, graft copolymers and hydrogels can sense environmental changes in the physiological range and it has found application in drug delivery in which subtle pH/temperature differences are important. Drug delivery systems have been prepared and tested with good results. Kinetics of the swelling/loading and release of some drugs have been also evaluated.
