Abstract:
Scientists from Johns Hopkins University have used metallic nanorods to transport genetic material into cells. The nanorods contained gold and nickel segments attached to different biomolecules. “We have been working on nonviral gene delivery - the method of transferring foreign genes or plasmid DNA into cells using nonviral means - for a decade,” Kam Leong told nanotechweb.org. “We use polycationic polymers to condense DNA into nanoparticles that can be taken up by cells, and deliver these DNA nanoparticles to different tissues in vivo.”
