Visualizing single molecules in whole cells with a new spin

Cell biologists traditionally use fluorescent dyes to label and visualize cells and the molecules within them under a microscope. With different super-resolution microscopy methods, they can even light up single molecules and their complex interactions with one another. However, the microscopy hardware that allows them to do this is highly specialized and expensive and hence, relatively rare in laboratories around the world, and the operation of such microscopes is daunting, as it requires unique skills.
