We reported the development of multifunctional poly (lactic-co-glycolic acid) (PLGA)-lecithin-polyethylene glycol (PEG) core-shell nanoparticles (NPs) that combined the beneficial properties of liposome and polymeric NPs for chemotherapeutics delivery. The particle size, surface charge and surface functional groups were easily tunable in highly reproducible manner by various formulation parameters such as lipid/polymer, 1, 2-distearoyl-sn-glycero-3-phosphoethanolamine (DSPE)-PEG-COOH/lecithin, DSPE-PEG-COOH/DSPE-PEG-NH2 mass ratio and modification of terminal groups of DSPE-PEG. We encapsulated model chemotherapy drug, hydrophilic cisplatin (DDP) or hydrophobic DDP prodrug, in the NPs and showed high encapsulation efficiency, excellent stability, specific FA targeting recognition for MCF-7 cells with over FA receptors expression and pretty cytotoxicity. Such PLGA–lecithin–PEG core-shell nanoparticles (NPs) were proved to be a promising drug delivery nanocarrier for cancer-targeted therapy.

多功能聚乳酸-羥基乙酸共聚物（PLGA）-卵磷脂-聚乙二醇（PEG）核殼納米粒子（NP）的開發(fā)，該納米粒子結(jié)合了脂質(zhì)體和聚合物NP的有益特性，用于藥物的輸送。

通過各種配方參數(shù)，如脂質(zhì)/聚合物、1,2-二硬脂�；�-sn-甘油-3-磷酸乙醇胺（DSPE）-PEG-COH/卵磷脂、DSPE-PEG-COOH/DSPE-PEG-NH2質(zhì)量比和DSPE-PEG末端基團的修飾，粒徑、表面電荷和表面官能團很容易以高度可重復的方式進行調(diào)節(jié)。

我們將模型化療藥物親水性順鉑（DDP）或疏水性DDP前藥封裝在NP中，并顯示出高封裝效率、優(yōu)異的穩(wěn)定性、對MCF-7細胞的特異性FA靶向識別，具有過FA受體表達和相當?shù)募毎�毒性。這種PLGA–卵磷脂–PEG核殼納米粒子（NP）被證明是一種很有前途的癌癥靶向治療藥物遞送納米載體。
