Carbon and graphene quantum dots (CQDs and GQDs), known as zero-dimensional (0D) nanomaterials have been attracting increasing attention in sensing and bioimaging. Their unique electronic, fluorescent, photoluminescent, chemiluminescent and electrochemiluminescent properties are what gives them potential in sensing. In this review, we summarize the basic knowledge on CQDs and GQDs before focussing on their application to sensing thus far followed by a discussion of future directions for research into CQDs and GQD-based nanomaterials in sensing are discussed. With regard to the latter, the authors suggest that with the potential of these nanomaterials in sensing more research is needed on understanding their optical properties and why the synthetic methods influence their properties so much, into methods of surface functionalization that provide greater selectivity in sensing and into new sensing concepts that utilise the virtues of these nanomaterials to give us new or better sensors that could not be achieve in other ways.
