Clustered, regularly interspaced short palindromic repeats (CRISPR)-based diagnoses, derived from gene-editing technology, have been exploited for less than 5 years and are now reaching the stage of precommercial use. CRISPR tools have some notable features, such as recognition at physiological temperature, excellent specificity, and high-efficiency signal amplification capabilities. These characteristics are promising for the development of next-generation diagnostic technologies. In this Perspective, we present a detailed summary of which micro/nanotechnologies play roles in the advancement of CRISPR diagnosis and how they are involved. The use of nanoprobes, nanochips, and nanodevices, microfluidic technology, lateral flow strips, . in CRISPR detection systems has led to new opportunities for CRISPR-based diagnosis assay development, such as achieving equipment-free detection, providing more compact detection systems, and improving sensitivity and quantitative capabilities. Although tremendous progress has been made, CRISPR diagnosis has not yet reached its full potential. We discuss upcoming opportunities and improvements and how micro/nanotechnologies will continue to play key roles.
基于成簇规律间隔短回文重复序列(CRISPR)的诊断方法源自基因编辑技术,应用时间还不到 5 年,目前已经进入商业化应用前期阶段。CRISPR 工具具有一些显著特点,如在生理温度下进行识别、极好的特异性和高效的信号放大能力。这些特点为开发下一代诊断技术提供了广阔的前景。在本观点文章中,我们详细总结了哪些微纳技术在推动 CRISPR 诊断方面发挥了作用,以及它们是如何发挥作用的。纳米探针、纳米芯片和纳米器件、微流控技术、侧向流条带等在 CRISPR 检测系统中的应用为基于 CRISPR 的诊断分析方法的发展带来了新的机遇,例如实现无设备检测、提供更紧凑的检测系统以及提高灵敏度和定量能力。尽管已经取得了巨大的进展,但 CRISPR 诊断尚未充分发挥其潜力。我们讨论了即将出现的机遇和改进,以及微纳技术将如何继续发挥关键作用。
