Quantitative phase imaging is a powerful, non-invasive and quantitative microscopy technique that allows multi-scale imaging of cellular systems, explain Mustafa Mir and Gabriel Popescu Imaging by ...

The system consists of a quantum cascade laser (QCL) that excites specific molecular bonds, causing localized heating that reduces the brightness of adjacent fluorescent molecules. Simultaneously, a ...

Using spatial light interference microscopy (SLIM) techniques developed by Gabriel Popescu, director of the lab, the researchers were able to show for the first time how human embryonic stem cell ...

It is the computational processing of images that reveals the finest details of a sample placed under all kinds of different light microscopes. Even though this processing has come a long way, there ...

What is the Diffraction Limit? The diffraction limit is a fundamental barrier in optical microscopy that sets the minimum size of features that can be resolved using conventional light microscopes. It ...

Our brain is a complex organ. Billions of nerve cells are wired in an intricate network, constantly processing signals, enabling us to recall memories or to move our bodies. Making sense of this ...
