Cloaking Devices Made from DNA-Equipped Nanoparticles
Jan-24-18
Gold nanoparticles equipped with DNA could lead to a new generation of cloaking materials.

Created by a team at Northwestern University, the metamaterial is made up of an optically active “superlattice” of gold nanoparticles connected by DNA strands. The DNA strands can change their length when exposed to different stimuli, which in turn alters the color of the material.

According to Koray Aydin, co-corresponding author of the study. "Our novel metamaterial platform – enabled by precise and extreme control of gold nanoparticle shape, size and spacing – holds significant promise for next-generation optical metamaterials and metasurfaces."
