Fluorescence microscopy has opened a whole new world of research for life scientists. Yet one of the biggest drawbacks of the technology has been its inability to visualize fast biochemical interactions. Now a team from University of Georgia in Athens and the University of California in San Francisco developed a method to substantially improve the visualization process, allowing for “100-nm resolution at frame rates up to 11 Hz for several hundred time points”.
Here’s a video page at Nature with clips showing the capabilities of the new technique…
