Polyethylenimine - Wikipedia
Polyethylenimine (PEI) or polyaziridine is a polymer with repeating units composed of the amine group and two carbon aliphatic CH 2 CH 2 spacers. Linear polyethyleneimines contain all secondary amines , in contrast to branched PEIs which …

Polyethylenimine (PEI) is a hydrophilic cationic polymer widely used as a nonviral nucleotide delivery reagent. Branched PEI can be synthesized by cationic ring-opening polymerization of aziridine. PEI-based particles can also be used as adjuvants for vaccines.
Bonding of Polyethylenimine in Covalent Organic Frameworks …
2024年12月16日 · We have developed a polyethylenimine-functionalized covalent organic framework (COF) for capturing CO 2 from the air. It was synthesized by the crystallization of an imine-linked COF, termed imine-COF-709, followed by linkage oxidation and polyamine installation through aromatic nucleophilic substitution.
Polyethyleneimine - an overview | ScienceDirect Topics
Polyethyleneimine (PEI) is a synthetic, water soluble, linear or branched polymer. It is widely used in gene delivery system due to the ability to build a complex with DNA and support the release of endosomal through “proton sponge effect.” It is also facilitating the intracellular transport into …

Polyethylenimine (linear) is a versatile cationic polymer with a high transfection efficiency. It is used as a gene delivery reagent. It is a non-lipid polycation that can be used to transfect oligonucleotides and plasmid into cells in vitro and in vivo.
Polyethylenimine (PEI) in gene therapy: Current status and clinical ...
2023年10月1日 · Polyethlyenimine (PEI) was introduced 1995 as a cationic polymer for nucleic acid delivery. PEI and its derivatives are extensively used in basic research and as reference formulations in the field of polymer-based gene delivery. Despite its widespread use, the number of clinical applications to date is limited.
Polyethyleneimine - an overview | ScienceDirect Topics
Polyethyleneimine (PEI) is a synthetic polymer with a highly branched network and a high cationic charge density. Due to its ability to condense nucleic acids and mediate endocytosis, PEI of various molecular weights or degrees of branching have been used to …
