Measuring the volume, motion and contents of microscopic droplets is important for studying how airborne viruses spread (including those that cause Covid-19), how clouds reflect sunlight to cool the ...

(Nanowerk Spotlight) Direct visualization and manipulation of individual carbon nanotubes (CNTs) in ambient conditions is of great significance for their characterizations and applications. However, ...

GLONIK has released a new 3D optical microscope that allows users to freely change their views, not only vertical view but also oblique views at arbitrary angles. GLONIK's patented technology provides ...

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 ...

Sneezes, rain clouds, and ink jet printers: They all produce or contain liquid droplets so tiny it would take several billion of them to fill a liter bottle. Measuring the volume, motion and contents ...

A single flat metalens now handles both excitation and fluorescence collection for diamond quantum sensors, enabling nanoscale sensing in spaces too tight for conventional optics. (Nanowerk Spotlight) ...

We use smartphones to talk, chat, play, and, by getting directions, explore the world we walk or drive through. Very soon, thanks to an Italian startup, we will also be able to use smartphones to ...

Super resolution: image taken using the new chip. (Courtesy: Bielefeld University / Robin Diekmann) A photonic chip that allows a conventional microscope to work at nanoscale resolution has been ...

Optical microscopes depend on light, of course, but they are also limited by that same light. Typically, anything under 200 nanometers just blurs together because of the wavelength of the light being ...
