Enhanced cellular uptake of nanoparticles by increasing the hydrophobicity of poly(lactic acid) through copolymerization with cell-membrane-lipid components†
Abstract
The influence of hydrophobicity on the internalization of polymeric nanoparticles (NPs) remains poorly investigated. The hydrophobicity of poly(L-lactide) was increased by copolymerization with cell-membrane-lipid components, and this significantly enhanced the uptake of NPs up to 60% in the human cervical cancer cell line in comparison to unmodified poly(L-lactide) NPs.
