Abstract

In recent years, temporal control of drug delivery has been of interest in basic and applied fields as a new approach to achieve improved drug therapies. This new drug delivery may be achieved by utilization of “intelligent” polymeric materials having the functions of sensing, processing and acting. Stimuli-responsive polymers have been investigated as potential molecular devices to achieve intelligent drug delivery systems such as self-regulating and externally nodulated drug delivery systems.

In this chapter, temperature responsive swelling-shrinking changes in hydrogels were reviewed from the view point of polymer-water interaction and polymer-polymer interaction. In particular, characteristics of interpenetrating polymer networks (IPN) constructed of two distinct polymers which lead to novel temperature-responsive swelling changes were discussed.
