General description
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).
