Abstract
En 中文
Super-resolution fluorescence microscopy has revolutionizedcellbiology over the past decade, enabling the visualization of subcellularcomplexity with unparalleled clarity and detail. However, the rapiddevelopment of image-scanning-based super-resolution systems stillrestrains convenient access to commonly used instruments such as epi-fluorescencemicroscopes. Here, we present multifocal scanning microscopy (MSM)for super-resolution imaging with simultaneous multicolor acquisitionand minimal instrumental complexity. MSM implements a stationary,interposed multifocal multicolor excitation by exploiting the motionof the specimens, realizing super-resolution microscopy through ageneral epi-fluorescence platform without compromising the image-scanningmechanism or inducing complex instrument alignment. The system isdemonstrated with various phantom and biological specimens, and theresults present effective resolution doubling, optical sectioning,and contrast enhancement. We anticipate MSM, as a highly accessibleand compatible super-resolution technique, to offer a promising methodologicalpathway for broad cell biological discoveries.
