Gold Nanoparticles News and Research

RSS

Gold nanoparticles are made up of metallic gold atoms to create a crystal structure of 1-100 nm.

Using Spherical Nucleic Acids to Track and Treat Disease

Spherical nucleic acids are structures that are made by taking a nanoparticle template and using chemistry to arrange short strands of DNA or RNA on the surface of those particles. The spherical core of the nanoparticle creates a spherical arrangement of DNA or RNA, similar to tiny little balls of nucleic acids.
