摘要
A RNA/DNA nanoparticle for delivering siRNA where a RNA transcript including at least one hairpin structure hybridizes DNA-cholesterol conjugate and folate-DNA conjugate including a complementary sequence to the RNA transcript, and a composition including the RNA/DNA nanoparticle is provided. More specifically, because various siRNA used for different applications can be contained in the RNA/DNA nanoparticle for delivering siRNA at a high loading efficiency, and has stability to the outer attacks such as nuclease degradation. The RNA/DNA nanoparticle siRNA can be prepared by self-assembly without using polycationic agent which is harmful agent for body. The folate targeting to various cancer cells can accumulate the nanoparticle selectively on target cancer cell after intravenous injection, and make excellent gene-silencing effect inside the cancer tissue, thereby being used as a good agent for treating cancers.
