Graphene, the first two-dimensional crystal ever studied, has made such an impact in a myriad of fields ranging from physical science to engineering that its discovery earned Nobel recognition in 2010. Although it was initially lauded as the answer to the Moore's law limitation of silicon electronics, what really captivated scientists was the fact that it opened countless avenues of exploration. From a synthetic chemists perspective, it became imperative to find a more sensible way to isolate graphene if it were ever to become practical for industrial use. This thesis demonstrates several fascinating routes to synthesize graphene, such as: top down methods involving the solution processing of graphitic materials through redox chemistry and bottom-up approaches mainly using chemical vapor deposition (CVD). In addition, several device architectures were developed to exploit intrinsic properties of the derived graphene. These applications include: transparent electrodes, Flash memory devices and bio-electrodes for cell stimulation.
