| 英文摘要 | Charge-reversal functional gold nanoparticles first prepared by layer-by-layer technique were employed to deliver small interfering rna (sirna) and plasmid dna into cancer cells. polyacrylamide gel electrophoresis measurements of sirna confirmed the occurrence of the charge-reversal property of functional gold nanoparticles. the expression efficiency of enhanced green fluorescent protein (egfp) was improved by adjuvant transfection with charge-reversal functional gold nanoparticles, which also had much lower toxicity to cell proliferation. lamin a/c, an important nuclear envelope protein, was effectively silenced by lamin a/c-sirna delivered by charge-reversal functional gold nanoparticles, whose knockdown efficiency was better than that of commercial lipofectamine 2000. confocal laser scanning microscopic images indicated that there was more cy5-sirna distributed throughout the cytoplasm for cyanine 5-sirna/polyethyleneimine/cis-aconitic anhydride-functionalized poly(allylamine)/polyethyleneimine/11-mercaptoundecanoic acid-gold nanoparticle (cy5-sirna/pei/pah-cit/pei/mua-aunp) complexes. these results demonstrate the feasibility of using charge-reversal functional gold nanoparticles as a means of improving the nucleic acid delivery efficiency. |
