We report a novel drug delivery system for apoptosis induction by a "smart" polymer vehicle possessing thermosensitivity and bioaffinity. The polymer chain was prepared by copolymerization of N-isopropylacrylamide and N-methacryloyloxysuccinimide. Cell-adhesive RGDS peptide was conjugated with the copolymer as a
A four-arm star block copolymer, comprised of a hydrophobic PMMA arm and an average of three hydrophilic poly(N-isopropylacrylamide) (PNIPAAm) arms were designed and synthesized from the molecular level. The amphiphilic star block copolymer is capable of self-assembling into micelles in

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.
By altering the physicochemical properties, smart or intelligent drug delivery systems can be designed to deliver therapeutic molecules on-demand. Learn more about the application of stimuli-responsive materials in drug delivery.
