Carbon Quantum Dots in Nanobiotechnology

There has been an outburst of attraction in the use of nanoparticles and nanomaterials for bioimaging, biosensing and other chemical and biological applications. At the leading edge of the new trend of the emerging nanoparticles in the carbonic nanomaterials family, fluorescent carbon quantum dots have drawn considerable attention due to their unique and tunable properties. In this chapter, an overview of the fundamental properties of carbon quantum dots is provided first. Then, it focuses majorly on the in-vivo and in-vitro bioimaging, biosensing, drug delivery, wound-dressing and photocatalysis applications of the nanomaterial. This chapter is expected to offer beneficial insight into the role of carbon quantum dots in biological applications and encourage more exploration on the topic.
