The emergence of carbon dots (CDs) as anticancer agents had sparked a transformation in cancer research and treatment strategies. These fluorescent CDs, initially introduced in the early 2000 s, possess exceptional biocompatibility, tunable fluorescence, and surface modification capabilities, positioning them as promising tools in biomedical applications.
The review encapsulates the transformative trajectory of green CDs as future anticancer nanomedicine, poised to redefine the strategies employed in the ongoing fight against cancer.
The versatility of CDs was rooted in their various synthesis approaches and sustainable strategies, enabling their adaptability for diverse therapeutic uses. In vitro studies had showcased CDs' selective cytotoxicity against cancer cells while sparing healthy counterparts, forming the basis for targeted therapeutic potential. This selectivity had been attributed to the reactive oxygen species (ROS) generation, which opened avenues for targeted interventions. The role of CDs in combination therapies, synergizing with chemotherapy, radiotherapy, and targeted approaches was then investigated to heighten their anticancer efficacy. Notably, in vivo studies highlight CDs' remarkable biocompatibility and minimal side effects, endorsing their translational promise. Integration with conventional cancer treatments such as chemotherapy, radiotherapy, and immunotherapy amplified the versatility and effectiveness of CDs. The exploration of CDs' applications in photo-induced treatments further solidified their significance, positioning them as photosensitizers (PS) in photodynamic therapy (PDT) and photothermal agents (PA) in photothermal therapy (PTT). In PDT, CDs triggered the generation of ROS upon light exposure, facilitating cancer cell elimination, while in PTT, they induced localized hyperthermia within cancer cells, enhancing therapeutic outcomes. In vitro and in vivo investigations validated CDs' efficacy in PDT and PTT, affirming their potential for integration into combination therapies. Looking ahead, the future of CDs in anticancer treatment encompasses bioavailability, biocompatibility, synergistic treatments, tumor targeting, artificial intelligence (AI) and robotics integration, personalized medicine, and clinical translation. This transformative odyssey of CDs as future anticancer agents is poised to redefine the paradigm of cancer treatment strategies.
碳点(CDs)作为抗癌剂的出现引发了癌症研究和治疗策略的变革。这些荧光碳点于21世纪初首次被引入,具有出色的生物相容性、可调节的荧光特性以及表面修饰能力,使其成为生物医学应用中颇具前景的工具。
本综述概括了绿色碳点作为未来抗癌纳米药物的变革轨迹,有望重新定义当前抗癌斗争中所采用的策略。
碳点的多功能性源于其多种合成方法和可持续策略,使其能够适应各种治疗用途。体外研究表明,碳点对癌细胞具有选择性细胞毒性,同时对健康细胞无害,这构成了其靶向治疗潜力的基础。这种选择性归因于活性氧(ROS)的产生,为靶向干预开辟了途径。随后研究了碳点在联合治疗中的作用,与化疗、放疗和靶向治疗方法协同作用,以提高其抗癌疗效。值得注意的是,体内研究突出了碳点显著的生物相容性和最小的副作用,证实了它们在转化应用方面的前景。与化疗、放疗和免疫疗法等传统癌症治疗方法相结合,扩大了碳点的多功能性和有效性。对碳点在光诱导治疗中的应用探索进一步巩固了它们的重要性,使其在光动力疗法(PDT)中作为光敏剂(PS),在光热疗法(PTT)中作为光热剂(PA)。在PDT中,碳点在光照下引发ROS的产生,促进癌细胞的清除,而在PTT中,它们在癌细胞内诱导局部热疗,提高治疗效果。体外和体内研究验证了碳点在PDT和PTT中的疗效,肯定了它们整合到联合治疗中的潜力。展望未来,碳点在抗癌治疗中的未来包括生物利用度、生物相容性、协同治疗、肿瘤靶向、人工智能(AI)和机器人技术整合、个性化医疗以及临床转化。碳点作为未来抗癌剂的这一变革之旅有望重新定义癌症治疗策略的范式。
