WebGraphene is an increasingly important nanomaterial exhibiting great promise in the area of nanotechnology. In this study, the azide-functionalized graphene derivative was synthesized as the ‘click’ reagent for preparation of polyvalent DNA– graphene conjugates, which provide an effective and stable platform to construct new functional nano-architectures. WebApr 28, 2024 · Graphene is the most popular nanomaterial, and for good reason. It is a sheet of one atom thick carbon and the first two-dimensional semiconductor discovered. It has properties like high electron mobility and chemical stability in salt water that make it an ideal electrical conduit for reporting the activity of our biological machinery.
