Faster CARS on the Horizon?
When it comes to microscopy, scientists want to get images fast – in just a matter of seconds. But despite all of the advantages of broadband CARS, the technique is still a bit on the slow side. Unlike many approaches to imaging biological specimens and other materials, such as fluorescence microscopy, coherent anti-Stokes Raman scattering (CARS) does not require any sample staining or chemical tagging, both of which can be invasive. The method is based on two laser pulses (pump and ...

Improving Plant Cell Analysis Requires Good TIRF
Total internal reflection is the curious interaction of light and matter that makes fiber optic telecommunications possible, but its use in biological imaging may be even more interesting still. In any method of fluorescence microscopy, control over...

The (Never Ending?) Search for Higher-Resolution Microscopy
Can optical microscopy further shred the Abbe diffraction limit? Is it important to even try? Until about two decades ago, optical microscopists were stuck viewing their samples with a resolution no better than 200 nm. Now, well-funded labs have...
