Abstract

The present application relates to a metal-nucleic acid nanoparticle which is a nanoparticle having a spherical structure formed by assembly of metal ions with nucleic acids via coordination. The preparation thereof is mixing a metal ion solution with a nucleic acid solution to obtain a mixture followed by vortex, heating, centrifugation, washing with water and resuspension to obtain the metal-nucleic acid nanoparticles.
