Abstract: Nanoparticles have some characteristics such as can combine with big fragment DNA,low immunogenic,good biocompatibility,easy to produce,which can protect DNA against the digestion of nuclease. The nanoparticles have a high stability in organisms and cells,which was difficult to be degraded. Nanoparticles can improve transfection efficiency. As a nonviral gene vector,the application of nanoparticles in gene therapy became research focus. In this article,we mainly discussed the characteristics of nanoparticles, characteristics and transport mechanism of nanoparticles as gene vector,the progress on nanoparticles as gene vector.

Key words: Nanoparticles, Gene vectors, Transfection
