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 ...

Stimulated Emission Depletion (STED) microscopy is a super-resolution imaging technique that overcomes the diffraction limit of conventional optical microscopy. It enables the visualization of ...

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 ...

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 ...

Light microscopy is a key tool that scientists use to image cells, organelles, subcellular structures, and molecules such as proteins and nucleic acids. Because visible light leaves biological ...

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 ...
