Abstract

Graphene-based nanomaterials have been widely explored in biomedical fields such as bioimaging, drug delivery, theranostics, and so on. In this chapter, we will review the recent advances in bioimaging of graphene-based nanomaterials, including graphene, graphene oxide, reduced graphene oxide, graphene quantum dots, and their derivatives. The synthetic methods of graphene-based nanomaterials are included in situ synthesis and binding method. The bioimaging modalities, including optical imaging (fluorescence [FL], two-photon FL), positron emission tomography/single-photon emission computed tomography, magnetic resonance imaging, photoacoustic imaging, Raman imaging, and multimodal imaging are highlighted. Finally, we will discuss the prospects and challenges of graphene-based nanomaterials in bioimaging.
