Inorganic nanoparticles as nucleic acid transporters into eukaryotic cells

The review is concerned with inorganic nanoparticles (gold, titanium dioxide, silica, iron oxides, calcium phosphate) used as nucleic acid transporters into mammalian cells. Methods for the synthesis of nanoparticles and approaches to surface modification through covalent or noncovalent attachment of low- or high-molecular-weight compounds are considered. The data available from the literature on biological action of nucleic acids delivered into the cells by nanoparticles and on the effect of nanoparticles and their conjugates and complexes on the cell survival are summarized. Pathways of cellular internalization of nanoparticles and the mechanism of their excretion, as well as the ways of release of nucleic acids from their complexes with nanoparticles after the cellular uptake are described.
