Progress of inorganic nanoparticles as gene delivery vectors

Transfection is defined as the delivery of functional nucleic acids into living cells, maintaining the biological function of the nucleic acids. As an important technique in biochemistry and molecular biology, transfection is meani.ngful for its potential applications in gene therapy. Inorganic nanoparticles can be used as gene delivery vectors and have received extensive interest due to their various advantages, such as easy preparation and surface-functionalization. This paper reviewed the current researches about inorganic nanoparticles as gene delivery vectors. Their influence on the gene expression was also discussed.
