The development of new antiviral nucleic acid-based drugs and the search for their efficient delivery into cells are an urgent task. We developed methods of immobilizing DNA fragments to titanium dioxide nanoparticles with the formation of TiO2∼DNA nanocomposites. It is shown that DNA fragments in nanocomposites retain their ability to form complementary complexes and can be delivered into cells without...
This paper presented a“Z” shape Au/Pt hybrid micro-nanorobot propelled by self electrophoresis driving. The Z shape hybrid micro-nanorobot realized itself rotational movement while having a parallel shift. The Z shape micro-nanorobot was designed for the drug delivery, biomedical engineering and so on. Just as its name implies, the mainly raw materials are platinum and gold. By the focus ion beam...
