Using light to measure ever-smaller objects has been central to progress in many scientific disciplines for centuries. As far back as 1873, German physicist Ernst Abbe proved that light diffraction ...

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 ...

The 3D micro-device consists of a modified coverslip and a micro-sphere fabricated by advanced MPL. It can enhance the lateral resolution beyond what is achievable with conventional optics. Today, ...

Bio: Seemantini Nadkarni is an Associate Professor at the Wellman Center for Photomedicine at Massachusetts General Hospital and Harvard Medical School with over 20 years of experience in innovating ...

Researchers from the Physical Chemistry and Theory departments at the Fritz Haber Institute have found a new way to image layers of boron nitride that are only a single atom thick. This material is ...

A project at Swiss research center EPFL has designed an add-on unit intended to bring structured light capability to a standard optical microscope. Described in Nature Communications, the design ...

It’s relatively easy to understand how optical microscopes work at low magnifications: one lens magnifies an image, the next magnifies the already-magnified image, and so on until it reaches the eye ...

Introduction to SNOM: The Scanning Near-field Optical Microscope (SNOM) stands as a pivotal analytical tool in nanotechnology, enabling the visualization of nanostructures with resolution beyond the ...

The smallest QR code in the world is so very tiny that your phone would need an electron microscope to scan it. The matrix ...

Jueden's experiment began by accident. While using a low-cost digital microscope to inspect electronics, he turned it toward a LaserDisc out of curiosity. Under magnification, faint ...
