Abstract
Description
Nobel prize winning material as "the thinnest material in our universe", graphene, a single atom thick sheet of sp2 carbon atoms, promises a diverse range of applications from composite materials to quantum dots, and even in several bioengineering applications. For graphene, that availability is encumbered by having to surmount the high cohesive van der Waals energy (5.9 kJ mol-1 carbon) adhering graphitic sheets to one another. Moreover, graphene being extremely hydrophobic, it has low solubility in water. Here we demonstrate the feasibility of developing biological graphene dispersions using wet chemistry and ultra sonication. 13C NMR spectra of graphene dispersions indicate the presence of graphene carbon signature in solution. Our future work is to use this graphene dispersion in a cellular assay to explore graphene-protein binding and also to study the graphene nanoribbon structures as contrast agents and drug delivery.
