For hundreds of years, the optical microscope was the only tool available to scientists wanting to study the movement of cells, bacteria and yeast. But the diffraction of light made it impossible to ...

This is the world’s smallest silicon (Si) light-emitting diode (LED) - smaller than the wavelength of light - with a light intensity comparable to much larger, state-of-the-art Si LEDs and with ...

Scientists at EPFL have published a guide to building an add-on that turns a standard optical microscope into an instrument capable of producing super resolution, 3D images of cells, organoids, and ...
