3D Conceptual Image for Lipid Nanotablet (IMAGE) Seoul National University Caption Red, gold, silver spheres on a lipid chip represent metal nanoparticles with strong and distinct scattering signals. The nanoparticles are functionalized with specially designed DNA ligands, and the surface ligands render receptor-floater interactions programmable, thereby transforming a pair of receptor and floater into a logic gate. These nanoparticle logic gates can be readily wired to form complex circuits.
