基于DNA的纳米材料在肿瘤治疗领域的研究进展

肿瘤治疗药物通常存在水溶性差、靶向性低、稳定性差、不易被肿瘤细胞摄取等不足，开发一种理想的药物递送载体仍是肿瘤治疗领域亟待解决的重要问题。由于具有良好的序列可编程性、生物相容性和生物可降解性，基于DNA的纳米材料已被广泛用作肿瘤治疗的药物递送载体。大量研究表明，DNA纳米材料可以有效装载肿瘤治疗药物，实现肿瘤组织靶向递送、高效细胞摄取与刺激响应性药物释放。本文从DNA纳米技术的历史与发展入手，例举DNA纳米材料作为药物递送载体在化疗、基因治疗、免疫治疗和光动力疗法中的应用进展，并对其未来发展进行展望，以期为该领域其他研究工作者提供参考。

Advances of DNA-based nanomaterials in tumor therapy

Antitumor drugs usually have deficiencies such as poor water solubility, low targeting, poor stability, and difficulty in being taken up by tumor cells. The development of an ideal drug delivery vehicle is still an urgent problem to be solved in the field of cancer therapy. Due to their excellent sequence programmability, biocompatibility and biodegradability, DNA-based nanomaterials have been widely used as drug delivery vehicles for cancer treatment. Numerous studies have shown that DNA nanomaterials can effectively load cancer therapeutic agents, and achieve tumor targeted delivery, efficient cellular internalization as well as stimuli-responsive drug release. Starting from the history and development of DNA nanotechnology, this review illustrates the application progress of DNA nanomaterial as drug delivery vehicle in chemotherapy, gene therapy, immunotherapy and photodynamic therapy, and the future development is prospected so as to provide some reference for other researchers in this field.
