Cornell University researchers achieve world's highest resolution images using ptychography

Researchers at Cornell University have used ptychography to achieve the highest resolution ever produced in an electron microscope. The team, led by David Muller, Professor of Applied and Engineering Physics, recently reported their findings in the July 19th issue of Nature, outlining their ability to resolve images to a resolution of 0.39 Å.

Phasefocus reports on new ptychography paper published in Nature Scientific Reports

Cell imaging often relies on synthetic or genetic fluorescent labels, to provide contrast which can be far from ideal for imaging cells in their in vivo state. We report on the biological application of a label-free, high contrast microscopy technique known as ptychography, in which the image producing step is transferred from the microscope lens to a high-speed phase retrieval algorithm.
