Abstract

Rolling circle replication (RCR), including rolling circle amplification (RCA) and rolling circle transcription (RCT), is an isothermal enzymatic reaction. Because of its high amplification efficiency, RCR is a powerful biosensing tool for detecting biomolecules. In recent years, RCR has also been extended to the field of bioimaging to better understand biological pathways. Furthermore, RCR provides a simple technique to design and generate DNA/RNA structures with unique advantages in delivering drugs and enhanced targeting ability. In this review, we introduce the fundamentals of RCR and describe the most recent advances in RCR-based detection methods and delivery vehicles for biosensing, bioimaging, and biomedicine. Finally, some challenges and further opportunities of RCR-based biotechnology are discussed.

摘要

滚环复制（RCR），包括滚环扩增（RCA）和滚环转录（RCT），是一种等温酶反应。由于其高扩增效率，RCR 是一种用于检测生物分子的强大生物传感工具。近年来，RCR 也已扩展到生物成像领域，以更好地了解生物途径。此外，RCR 提供了一种简单的技术来设计和生成具有独特优势的 DNA/RNA 结构，在药物输送和增强靶向能力方面具有优势。在这篇综述中，我们介绍了 RCR 的基本原理，并描述了基于 RCR 的检测方法和生物传感、生物成像和生物医学的输送载体的最新进展。最后，讨论了基于 RCR 的生物技术的一些挑战和进一步的机会。
