与传统的系综方法相比,在单分子水平上研究大分子可以揭示生物反应的异常清晰甚至令人惊讶的观点。在过去的20年里,单分子技术经历了非常迅速的发展,这些尖端技术通过促进单分子的操作和检测而彻底改变了生物研究。在这里,我们简要地介绍了这些先进的技术,包括光钳、磁钳、原子力显微镜(AFM)、流体动力学流动拉伸分析和单分子荧光共振能量转移(SmFRET)。我们试图描述它们的基本原理,并提供每种技术的几个应用示例。这篇综述旨在为有生物学或生物物理学背景的观众提供一个相当介绍性的单分子技术概述。
Compared to conventional ensemble methods, studying macromolecules at single-molecule level can reveal extraordinary clear and even surprising views for a biological reaction. In the past 20 years, single-molecule techniques have been undergoing a very rapid development, and these cutting edge technologies have revolutionized the biological research by facilitating single-molecule manipulation and detection. Here we give a brief review about these advanced techniques, including optical tweezers, magnetic tweezers, atomic force microscopy (AFM), hydrodynamic flow-stretching assay, and single-molecule fluorescence resonance energy transfer (smFRET). We are trying to describe their basic principles and provide a few examples of applications for each technique. This review aims to give a rather introductory survey of single-molecule techniques for audiences with biological or biophysical background.
