How to cook up a better batch of graphene

We've called the Nobel-prize-winning graphene the rock star of the nanotech world, and now Michael Berger at Nanowerk explains how graphene can be created with hollow capsules that will open up new avenues of drug delivery. "By taking advantage of versatile nano-size control assembly, we have demonstrated the successful formation of three-dimensional hollow graphene oxide capsules," South Korean researcher Byeong-Su Kim tells Nanowerk. "We anticipate that the results presented in our study will provide a basis for designing various hollow graphene structures to open new possibilities in catalysis, porous graphene membranes, drug delivery and electrochemistry."
