The ubiquitous applications in which graphene plays an integral role has made it essential to develop a facile, cheap, environmentally-friendly and scalable manufacturing technique, that can meet its ever-growing demand. This thesis investigates a mechano-chemical method to exfoliate Few-Layered Graphene (FLG) dispersions. A common protein, Bovine Serum Albumin (BSA) is implemented that has been found to improve the effectiveness of the exfoliation process as well as prevent graphene layers from aggregating back after it has been separated. Moreover, Astrocytes cells were brought in contact with the developed BSA-FLG dispersions in order to test for cell cytotoxicity as a part of a preliminary study. The results indicate that cells thrived when subjected to BSA-FLG dispersions up until a certain concentration. In addition, an exhaustive literature review on existing ball milling techniques that have been used to synthesize graphene has been included.
