Controlled Assembly of Charged Nanoparticles Using Functionalized Graphene Nanomesh

摘要

A method, an apparatus and an article of manufacture for attracting charged nanoparticles using a graphene nanomesh. The method includes creating a graphene nanomesh by generating multiple holes in graphene, wherein each of the multiple holes is of a size appropriate to a targeted charged nanoparticle, selectively passivating the multiple holes of the graphene nanomesh to form a charged ring in the graphene nanomesh by treating the graphene nanomesh with chemistry yielding a trap with an opposite charge to that of the targeted nanoparticle, and electrostatically attracting the target charged nanoparticle to the oppositely charged ring to facilitate docking of the charged nanoparticle to the graphene nanomesh.
