Properties
Description
PEI(5k)-PEG(10k)-PEI(5k) is a linear amphiphilic block copolymer with polyethylene glycol (PEG) and poly(ethylene imine) (PEI). This polymer can be used in lipid nanoparticles.
Molecular Weight
PEI(5 kDa), PEG(10 kDa), PEI(5 kDa)
Identity
Confirmed by NMR.
Applications
PEI(5k)-PEG(10k)-PEI(5k) can be used to construct delivery systems for slow and controlled release of loaded molecules by controlling the degradation rate of the polymer and the molecule release behavior.
