Polymeric supramolecular systems for drug delivery

Abstract

Recent advances in supramolecular chemistry have had significant influence on the biomedical applications of materials chemistry. Supramolecular systems are based on weak and reversible non-covalent interactions, such as hydrogen bonding, metal coordination, hydrophobic attractions, van der Waals forces, π–π, and electrostatic interactions. Because of the weak and reversible nature of the molecular interactions in self-assembled supramolecular systems, they are excellent candidates for the design of drug delivery systems (DDS). In DDS, therapeutic agents can be temporarily encapsulated into the carrier vehicles and released at a specific site or with designated timing. Using DDS, the effectiveness of existing drugs can be optimized, which sometimes provides new indications. DDS must have not only optimal drug loading capacities and release properties, but also be biocompatible with low toxicity. Many types of biocompatible polymeric materials have already been developed for self-assembled drug formulations. Current studies on DDS are aiming at target-specific delivery of therapeutic agents and stimuli-responsive drug release. In this feature article, we will overview polymeric supramolecular systems for target-specific drug delivery and stimuli-responsive drug release.
