  具有诊断与治疗功能一体化的纳米光诊疗剂(Phototheranostics)开拓了肿瘤治疗模式的新途径,它具备选择性好、毒性低微、创伤小、风险小、疼痛轻等优点,已经成为国际纳米生物医药领域中的研究热点之一。迄今为止,用于光诊疗剂研究的纳米材料主要有金纳米棒、纳米碳管、Ⅱ-Ⅳ量子点、磁性纳米粒子、上转换纳米颗粒、氧化石墨烯等。尽管以上纳米材料构建的光诊疗剂研究已经取得了大量的成果,但开发稳定低毒、多功能纳米光诊疗剂用于癌症的早期诊断和治疗仍然是一个迫切需要解决的科学问题。最近,我们稳定低毒的碳点光敏剂为研究对象,发现了一系列可用于多模态成像(荧光、光声、光热和磁共振成像)介导的光动力治疗肿瘤的碳点基纳米光诊疗剂,这些新型碳点基纳米材料光诊疗剂低毒性、光疗效果好,有望成为肿瘤治疗新一代纳米光疗药物。
