Description générale

Polyethylenimine(PEI) is a synthetic cationic polymerwith high charge density and chain flexibility. It is the most widelyinvestigated cationic polymer for non-viral delivery of nucleic acids. LinearPEI can be an effective carrier for a wide range of gene medicine including DNAplasmids, small interfering RNAs, and mRNAs. It protects the DNA from theacidic environment and ensures the release of DNA to the cytoplasm.

Application

  • Water-soluble linear poly (ethylenimine) as a superior bifunctional binder for lithium–sulfur batteries: Demonstrates the utility of water-soluble linear polyethylenimine as an effective bifunctional binder that enhances the cycle stability and efficiency of lithium-sulfur batteries, pivotal for advancing battery technology (Liao et al., 2018).

Delivery of Nucleic Acids Using Polymers

Gene therapy has become one of the most discussed techniques in biomedical research in recent years.

Professor Yoshiki Katayama (Kyushu University, Japan) discusses recent advances in drug delivery systems and strategies that exploit the EPR effect, with a special focus on stimuli-responsive systems based on novel materials.

Wide range of functional polymers for biomedical applications have been synthesized and structurally characterized. Several classes of polymers including biodegradable polymers, hydrophilic & amphiphilic polymers, and stimuli responsive polymers have been prepared using controlled and directed functionalization via "living" polymerization such as RAFT, ionic and ring opening polymerization. Selected polymers have been studied for their structure-properties relationship. "
