Gene delivery vectors must deliver their cargoes into the cytosol or the nucleus, where DNA or siRNA functions in vivo. Therefore it is crucial for the rational design of the nucleic acid delivery carriers. Compared with viral vectors, non-viral vectors have overcome some fatal defections in gene therapy. Whereas the most important issue for the non-viral vectors is the low transfection efficiency, which hinders the progress of non-viral carriers. Sparked by the structures of the virus and understanding of the process of virus infection, various biomimic structures of non-viral carriers were designed and prepared to improve the transfection issues in vitro and in vivo. However, less impressive results are achieved. In this review, we will investigate the evolution of the virus-mimicking carriers of nucleic acids for gene therapy, especially in cancer therapy; explore and discuss the relationship between the structures, materials and functions of the carriers, to provide guidance for establishing safe and highly efficient non-viral carriers for gene therapy.
