Visualizing single molecules in whole cells with a new spin

ScienceDaily.com: Nanotechnology News - Tue, 12/12/2017 - 21:54
Scientists have adapted DNA-PAINT technology to microscopes that are widespread among cell biology laboratories, called confocal microscopes, and that are used by researchers to image whole cells and thicker tissues at lower resolution. They have demonstrated that the method can visualize a variety of different molecules, including combinations of different proteins, RNAs and DNA throughout the entire depth of whole cells at super-resolution.
