Paper Abstract

Graphene is gaining importance due to its unique properties following initial isolation and characterization in 2004. Graphene’s reported applications in electronics and medical disciplines are numerous and expanding. Accordingly, graphene quantum dots (GQDs) are gaining significance for their unique optical and electronic properties including characteristic photoluminescence when excited by UV light. Because GQDs are chemically inert and contain low levels of toxicity, they are attractive for in-vivo and intra-operational cancer imaging and diagnostic applications. GQDs can be formed through the bottom-up method of pyrolysis of non-toxic organic acids such as citric acid and L-glutamic acid. In this paper, GQDs formed from L-aspartic acid using a simple, bottom-up method are studied in detail for the first time. Absorption characteristics are studied using spectroscopic techniques. Results and future efforts are then discussed.
