Due to its unique physical and chemical characteristics, DNA, which is known only as genetic information, has been identified and utilized as a new material at an astonishing rate. The role of DNA has increased dramatically with the advent of various DNA derivatives such as DNA-RNA, DNA-metal hybrids, and PNA, which can be organized into 2D or 3D structures by exploiting their complementary recognition. Due to its intrinsic biocompatibility, self-assembly, tunable immunogenicity, structural programmability, long stability, and electron-rich nature, DNA has generated major interest in electronic and catalytic applications. Based on its advantages, DNA and its derivatives are utilized in several fields where the traditional methodologies are ineffective. Here, the present challenges and opportunities of DNA transformations are demonstrated, especially in biomedical applications that include diagnosis and therapy. Natural DNAs previously utilized and transformed into patterns are not found in nature due to lack of multiplexing, resulting in low sensitivity and high error frequency in multi-targeted therapeutics. More recently, new platforms have advanced the diagnostic ability and therapeutic efficacy of DNA in biomedicine. There is confidence that DNA will play a strong role in next-generation clinical technology and can be used in multifaceted applications.
由于其独特的物理和化学特性,原本仅作为遗传信息为人所知的DNA,已以惊人的速度被识别并用作一种新材料。随着各种DNA衍生物的出现,如DNA - RNA、DNA - 金属杂化物和肽核酸(PNA),DNA的作用急剧增加,这些衍生物可以通过利用其互补识别作用组装成二维或三维结构。由于其固有的生物相容性、自组装性、可调节的免疫原性、结构可编程性、长期稳定性以及富含电子的特性,DNA在电子和催化应用方面引起了极大的关注。基于其优势,DNA及其衍生物被应用于一些传统方法无效的领域。在此,展示了DNA转化当前面临的挑战和机遇,特别是在包括诊断和治疗在内的生物医学应用中。由于缺乏多重性,以前使用并转化为图案的天然DNA在自然界中并不存在,这导致多靶点治疗中的灵敏度低和错误频率高。最近,新的平台提高了DNA在生物医学中的诊断能力和治疗效果。人们相信DNA将在下一代临床技术中发挥重要作用,并可用于多方面的应用。
