Properties
Description
PEI(10k)-PEG(1k)-PEI(10k) is a block copolymer contains polyethylene glycol (PEG) in the center and poly(ethylene imine) (PEI) at the ends. The hydroxyl group enables further derivatization or replacement with other reactive functional groups.
Molecular Weight
PEI(10 kDa), PEG(1 kDa), PEI(10 kDa)
Identity
Confirmed by NMR.
Applications
PEI(10k)-PEG(1k)-PEI(10k) can be used to modify the surface properties of nanoparticles, reducing their toxicity and improving their targeting ability.
