Light-shrinking material lets ordinary microscope see in super resolution

Electrical engineers at the University of California San Diego developed a technology that improves the resolution of an ordinary light microscope so that it can be used to directly observe finer structures and details in living cells.

The technology turns a conventional light microscope into what’s called a super-resolution microscope. It involves a specially engineered material that shortens the wavelength of light as it illuminates the sample—this shrunken light is what essentially enables the microscope to image in higher resolution.
