Abstract

Carbon dots (CDs, sp2 hybrid carbon particles) as a new type of biocompatible nanomaterials have received much attention because of their low toxicity, good water dispersability, ease of fabrication and functionalization, and outstanding photostability. Recently, they have been explored intensively to serve as biosensors and bioimaging agents for various bio-applications. In this chapter, we will introduce the fundamental properties of CDs and focus on their recent applications in biosensing and bioimaging. We will also summarize the recent progress in their fabrication and application in biomedical imaging, interactions with biomolecules, electrochemical biosensors. In addition, the remaining challenges and perspectives for future developments are also briefly discussed. We hope this chapter will provide some critical insights to inspire more exciting work on CDs for biological applications (sensing and imaging) in the near future.
