WebApr 11, 2012 · Despite high molecular weight (MW) branched polyethylenimine (bPEI) is considered the gold standard polymeric transfectant, it suffers from high cytotoxicity. Inversely, its low MW counterpart is ... WebWe have synthesized a novel gene delivery vector by covalently combining branched polyethylenimine (bPEI) and hyaluronic acid (HA) with the aim of improving transfection of bPEI into human mesenchymal stem cells (hMSCs) while maintaining cell viability. Because of the opposite charges on bPEI and HA, the bPEI-HA vector forms a zwitterionic ...
WebApr 10, 2024 · We modified ZIF-8 and prepared branched polyethylenimine-grafted ZIF-8 (BPEI-ZIF-8) with an in situ synthesis method. The BPEI-ZIF-8 that was created using this technique contained a significant quantity of -NH 2 on the surface, which could chemically react with epoxy groups. BPEI-ZIF-8 and ionic liquids were combined to obtain BPEI-ZIF … WebHighly porous foams based on graphene oxide functionalized with polyethylenimine are generated and used with unprecedented efficiency for adsorbing heavy metal ions. A multiscale analysis of the GO–BPEI nanocomposite provided evidence for the covalent grafting of BPEI on GO and the formation of low crystalline porous foams.
WebMethicillin-resistant Staphylococcus aureus (MRSA) is a medical concern. Here, we show that branched polyethylenimine (BPEI), a nontoxic, cationic polymer, restores MRSA’s susceptibility to β-lactam antibiotics. Checkerboard assays with MRSA demonstrated synergy between BPEI and β-lactam antibiotics. A time-killing curve showed BPEI to be … WebBranched Polyethylenimine, Mw ~2,000 (bPEI 2000) is a colorless to yellowish liquid. It is a water soluble polyamine with high cationic charge density. bPEI 2000 contains primary, secondary, and tertiary amine groups in approximately 40/36/24 ratio.
