Spherical nucleic acids
The floating golden sphere, bristling with corkscrew strands of RNA, drifts majestically toward the jostling lipid bilayer that surrounds a cell. Slowly, gently, it squeezes through the layer until it is inside the cell. Breezing across cell membranes is just one talent of these spherical nucleic acids (SNAs) developed by nanotechnology pioneer Chad Mirkin at Northwestern University and explained in the video created by Quintin Anderson of the scientific animation firm, The Seagull Company. The objective is to give the audience an overview of how the properties of SNAs make them favorable for therapeutic treatments and medical diagnostics.
