he development of stimuli-responsive nanodevices with high efficiency and specificity is very important in biosensing, drug delivery, and so on. DNAzymes are a class of DNA molecules with the specific catalytic activity. Owing to their unique catalytic activity and easy design and synthesis, the construction and application of DNAzymes-based nanodevices have attracted much attention in recent years. In this review, the classification and properties of DNAzyme are first introduced. The construction of several common kinds of DNAzyme-based nanodevices, such as DNA motors, signal amplifiers, and logic gates, is then systematically summarized. We also introduce the application of DNAzyme-based nanodevices in sensing and therapeutic fields. In addition, current limitations and future directions are discussed.
开发具有高效性和特异性的刺激响应性纳米器件在生物传感、药物递送等领域非常重要。脱氧核酶是一类具有特定催化活性的DNA分子。由于其独特的催化活性以及易于设计和合成，近年来基于脱氧核酶的纳米器件的构建和应用备受关注。在这篇综述中，首先介绍了脱氧核酶的分类和性质。然后系统地总结了几种常见的基于脱氧核酶的纳米器件的构建，如DNA马达、信号放大器和逻辑门。我们还介绍了基于脱氧核酶的纳米器件在传感和治疗领域的应用。此外，讨论了当前的局限性和未来的发展方向。
