Graphene quantum dots (GQDs) have been widely studied in recent years due to its unique structure related properties, such as optical, electrical and optoelectrical properties. Furthermore, GQDs are environment friendly due to its non-toxic and biologically inert properties, which have attracted worldwide interests from academic and industry. This review introduces quantum dots (QDs) and explores their applications, delivery systems in biology. QDs are one of the first nanotechnologies to be integrated with the biological sciences and are widely anticipated to eventually find application in a number of commercial consumer and clinical products. The various applications of GQDs in biological imaging, photodynamic therapy, electrochemical sensors and use in drug delivery and medicine are described. GQDs composites, having optimized contents and properties, are also discussed to extend the applications of GQDs.
