The study of different genes, chromosomes and the spatiotemporal relationship between them is of great significance in the field of biomedicine. CRISPR-Cas9 has become the most widely used gene editing tool due to its excellent targeting ability. In recent years, a series of advanced imaging technologies based on Cas9 have been reported, providing fast and convenient tools for studying the sites location of genome, RNA, and chromatin. At the same time, a variety of CRISPR-Cas9-based imaging systems have been developed, which are widely used in real-time multi-site imaging . In this review, we summarized the component and mechanism of CRISPR-Cas9 system, overviewed the NIR imaging and the application of NIR fluorophores in the delivery of CRISPR-Cas9, and highlighted advances of the CRISPR-Cas9-based imaging system. In addition, we also discussed the challenges and potential solutions of CRISPR-Cas9-based imaging methods, and looked forward to the development trend of the field.
研究不同的基因、染色体以及它们之间的时空关系在生物医学领域具有重要意义。CRISPR-Cas9因其出色的靶向能力已成为应用最为广泛的基因编辑工具。近年来，一系列基于Cas9的先进成像技术被报道，为研究基因组、RNA和染色质的位点定位提供了快速便捷的工具。同时，多种基于CRISPR-Cas9的成像系统也已被开发出来，并广泛应用于实时多位点成像。在本综述中，我们总结了CRISPR-Cas9系统的组成和机制，概述了近红外成像以及近红外荧光团在CRISPR-Cas9递送中的应用，并重点介绍了基于CRISPR-Cas9的成像系统的进展。此外，我们还讨论了基于CRISPR-Cas9的成像方法所面临的挑战和潜在解决方案，并展望了该领域的发展趋势。
