carbon-based nanomaterials, were highly studied by the research community, by
virtue of their particular properties, which enable a wide range of biological
applications, going from chemo- and biosensing to fluorescence imaging and
drug delivery. They are characterized by excellent fluorescence emission, which
can be modulated from the visible to near-infrared (NIR), and their surface is rich
in functional groups, which enable their functionalization with a wide range of
receptors and bio-functionalities (i.e., enzymes, etc.). They also exhibit extremely
low toxicity and excellent biocompatibility, which are useful for real-world
biological applications. On the other hand, CDs are also expected to reduce the
cost of biosensors by replacing both the noble metal substrates and the wellknown quantum dots based on metal chalcogenides. Their synthesis is based on
simple and sustainable approaches that could employ cheap and “greener” starting materials coming from biomass or agro-industrial waste. In this context,
the present chapter will focus on CDs as new sustainable nanomaterials for
biosensor applications, with particular care to optical and electrochemical biosensors. A short overview of the green sy
