TL;DR: Results indicated that PLL-SiNP was a novel nonviral nanoparticle gene vector, and would probably play an important role in gene structure and function research as well as gene therapy.
Abstract: DNA delivery is a core technology for gene structure and function research as well as clinical settings. The ability to safely and efficiently targeted transfer foreign DNA into cells is a fundamental goal in biotechnology. With the development of nanobiotechnology, nanoparticle gene vectors brought about new hope to reach the goal. In our research, silica nanoparticles (SiNP) were synthesized first in a microemulsion system polyoxyethylene nonylphenyl ether (OP-10)/cyclohexane/ammonium hydroxide, at the same time the effects of SiNP size and its distribution were elucidated by orthogonal analysis; then poly-L-lysine (PLL) was linked on the surface of SiNP by nanoparticle surface energy and electrostatically binding; lastly a novel complex nanomateial—poly-L-lysine-silica nanoparticles (PLL-SiNP) was prepared. The analysis of plasmid DNA binding and DNase I enzymatic degradation discovered that PLL-SiNP could bind DNA, and protect it against enzymatic degradation. Cell transfection showed that PLL-SiNP could efficiently transfer PEGFPC-2 plasmid DNA into HNE1 cell line. These results indicated that PLL-SiNP was a novel nonviral nanoparticle gene vector, and would probably play an important role in gene structure and function research as well as gene therapy.
