Poly-L-Lysine graft PEG or PEG-grafted-PLL 聽(PLL-g-PEG, PEG-g-PLL) is is a random graft co-polymer with a poly(L-lysine) backbone and poly(ethylene glycol) side-chains. 聽For surface modification, the PLL backbone interacts electrostatically with the substrate, while the side-chains extend from the surface to form a densely packed polymeric brush. PLL-g-PEG can be used 聽to prepare nanoparticles for gene/drug delivery.
