荧光超分辨显微技术自20世纪90年代诞生以来,经历了多代创新与发展,其空间分辨率已经远超衍射极限,横向分辨率能够达20 nm以下,可以实现分子尺度的生物成像与动态追踪。新一代超高分辨率显微技术的产生得益于传统超分辨技术的深度发展和结合创新。详细介绍横向分辨率在亚20 nm尺度的新一代荧光超分辨显微技术,并阐述其与传统超分辨原理的联系与区别。此外,针对分辨率的限制因素,就光学系统、扫描策略和样品制备等方面进行探讨,并展望高分辨率荧光显微技术在生物医学领域中的应用前景和发展方向。
Advances in Sub-20-nm Fluorescence Super-Resolution Microscopy(Invited)
Fluorescence super-resolution microscopy has undergone several rounds of innovation and development since the 1990s.The spatial resolution of fluorescence super-resolution microscopy exceeds the diffraction limit by a wide margin,achieving a lateral resolution below to~20 nm and enabling imaging and tracking at the molecular level.The latest generation of ultrahigh-resolution microscopy is the product of extensive development and innovative combination of conventional super-resolution techniques.This review aimed to introduce the new generation of fluorescence super-resolution microscopy at a sub-20-nm scale lateral resolution,and we also elucidated their similarities and differences compared with the conventional super-resolution techniques.Additionally,this review explored how emerging technologies optimize optical systems,scanning strategies,and sample preparation to improve resolution.Finally,we discussed the potential applications and development of high-resolution fluorescence microscopy in biomedical research.
