POLYMERIC SYSTEM FOR DRUG DELIVERY AND SOLUTE SEPARATION |
摘要 |
Described is a composite polymeric system to provide enhanced stimuli-responsiveness. The first aspect provides particles where the particles are made of stimuli-responsive polymer which responds to various stimuli such as temperature and pH change. Incorporated with this particle is a second polymer which in turn is relatively insensitive to stimuli. The invention can be potentially applied to other systems comprising a swellable hydrogel and a nonswellable hydrophobic polymer.
