Designing siRNA-conjugated plant oil-based nanoparticles for gene silencing and cancer therapy.

In this study, the anticancer activities of two siRNA carriers were compared using a human lung adenocarcinoma epithelial cell line (A549). Firstly, poly(styrene)-graft-poly(linoleic acid) (PS--PLina) and poly(styrene)-graft-poly(linoleic acid)-graft-poly(ethylene glycol) (PS--PLina--PEG) graft copolymers were synthesized by free-radical polymerization. PS-PLina and PS-PLina-PEG nanoparticles (NPs) were prepared by solvent evaporation method and were then characterized.
