Abstract
Expansion microscopy (ExM) is an innovative super-resolution imaging technique that utilizes physical expansion to magnify biological samples, facilitating the visualization of cellular structures that are challenging to observe using traditional optical microscopes. The fundamental principle of ExM revolves around employing a specialized hydrogel to uniformly expand biological samples, thereby achieving super-resolution imaging under conventional optical imaging conditions. This technology finds application not only in various biological samples such as cells and tissue sections, but also enables super-resolution imaging of large biological molecules including proteins, nucleic acids, and metabolite molecules. In recent years, numerous researchers have delved into ExM, resulting in the continuous development of a range of derivative technologies that optimize experimental protocols and broaden practical application fields. This article presents a comprehensive review of these derivative technologies, highlighting the utilization of ExM for anchoring nucleic acids, proteins, and other biological molecules, as well as its applications in biomedicine. Furthermore, this review offers insights into the future development prospects of ExM technology.
