PLGA-PEG/PEI NANOPARTICLES AND METHODS OF USE

摘要

Provided herein is a composition comprising a nanoparticle comprising poly(lactic acid-co-glycolic acid) (PLGA)-b-polyethylene glycol (PEG) (PLGA-PEG) copolymer formulated with polyethylenimine (PEI), and one or more cargo molecules (e.g., a nucleic acid molecule with or without a small molecule compound) associated with the nanoparticle. The nucleic acid molecule may be a plasmid or minicircle DNA expressing a gene or genes, CRISPR/Cas9 components, or an RNA molecule (e.g., small interfering RNA, miRNA, or lncRNA). Also provided are methods for delivering a cargo molecule to a cell in vitro and in vivo using the aforementioned composition.
