Nature Methods' Method of the Year 2008 goes to super-resolution
fluorescence microscopy. This series of articles—and the related movie—
showcase how these novel imaging methods came into their own in 2008 and the
incredible impact they promise to have in biological research. The Methods
to Watch feature provides a glimpse of future Methods of the Year and the

的限制,这一点和亮斑是很不同的。
对另一种基于统计的方法就不是很理解了,有哪位高人指点一下? |

Stimulated Emission Depletion microscopy, or STED microscopy, is a technique
that uses the non-linear de-excitation of fluorescent dyes to overcome the
resolution limit imposed by diffraction with standard confocal laser
scanning microscopes and conventional far-field optical microscopes [1].
A confocal laser scanning microscope uses a focused laser beam to illuminate
a small part of the sample being observed. The laser is tuned to a
frequency

What fitting a PSF is to localization, photo-activated localization
microscopy (PALM) is to "resolution"—this term is here used loosely to mean
measuring the distance between objects, not true optical resolution. Eric
Betzig and colleagues developed PALM;[12] Xiaowei Zhuang at Harvard used a
similar techniques and calls it STORM: stochastic optical reconstruction
microscopy.[13] The basic premise of both techniques is to fill the imaging
area with many dark fluorophores that can be p |
