Physicist Thomas Juffmann examines how electron microscopy enables us to obtain images that provide as much information as possible per detected photon/electron or per interaction with the sample. In 2016, Juffmann developed an imaging method at Stanford University, which can provide images with a better signal-to-noise ratio per photon/electron. With this method, every single photon/electron repeatedly interacts with the sample, leading to a signal amplification. In a publication of 2017, Juffmann and his colleagues showed that this method could make it possible to show the folding of a single protein. In the framework of an international collaboration, financed by the Gordon and Betty Moore Foundation, the physicist currently works on a first prototype of such a microscope.
