用基于季铵离子的氨基氧基和肟醚底物对氧化铁纳米颗粒进行功能化,为生成磁性基因递送载体提供了灵活的途径。使用 MCF-7 乳腺癌细胞系,我们的研究结果表明,基于荧光素酶测定,在有或没有磁辅助的 10% 血清存在下,源自脂质包被纳米颗粒制剂 dMLP 的 pDNA 磁复合物转染水平显着高于常用的阳离子脂质体制剂。目前的离子对、点击化学方法为 Fe3O4 纳米粒子提供了脂质层。所得磁性纳米载体可用作转染非活性材料的转染增强剂。
Functionalization of iron oxide nanoparticles with quaternary ammonium ion-based aminooxy and oxime ether substrates provides a flexible route for generating magnetic gene delivery vectors. Using the MCF-7 breast cancer cell line, our findings show that pDNA magnetoplexes derived from the lipid-coated nanoparticle formulation dMLP transfect in the presence of 10% serum with or without magnetic assistance at significantly higher levels than a commonly used cationic liposome formulation, based on luciferase assay. The present ionpairing, click chemistry approach furnishes Fe3O4 nanoparticles with lipid layers. The resultant magnetic nanovectors serve as transfection enhancers for otherwise transfection-inactive materials.
