Properties
Description
PEI(2k)-PEG(10k)-PEI(2k) is an amphiphilic block copolymer with a polyethylene glycol (PEG) in the center and two poly(ethylene imine) (PEI) at the ends. The polymer can be used in the development of lipid nanoparticles.
Molecular Weight
PEI(2 kDa), PEG(10 kDa), PEI(2 kDa)
Identity
Confirmed by NMR.
Applications
PEI(2k)-PEG(10k)-PEI(2k) can be used to construct pH-sensitive active molecule delivery systems that release active molecules in response to changes in the local pH environment.
