Role of CDs in Photo thermal (PTT) and Photo dynamic (PDT) therapy. PTT: after the cellular internalization of CDs, laser light irradiation (mostly near infrared) is used which is absorbed by the CDs to generate local heat and destroy diseased tissue. PDT: CDs carry a photosensitizer into the cellular system. Upon laser light irradiation, free radicals/reactive oxygen species are generated, leading to cancer cell death
