In this chapter we will have a look into the synthesis, structure, and applications of CDs on biomedical science such as bioimaging, biosensors, drug and gene delivery, and photodynamic therapy. Photodynamic therapy is the method to transfer light energy to its surrounding using photosensitizer structure trials, which showed meaningful response to this approach in many types of malignancies, CDs could be a suitable option to use as photosensitizers. © 2023 Walter de Gruyter GmbH, Berlin/Boston.en10.1515/9783110799958-009info:eu-repo/semantics/closedAccessBiomedical sciences; Cancer; Carbon dots; Nanoparticles; Photodynamic therapyBook Chapter2171892-s2.0-85159172129
