The Foldscope is constructed out of greeting card paper, a watch battery, and a dirt cheap lens. But don’t be fooled, you can use it to detect more than 20 diseases. Many of the world’s most fatal and ...

Which digital microscopes are best? Whether an academic researcher or a casual hobbyist, the microscope is an essential part of nearly every scientist’s toolkit. While all microscopes let you examine ...

MR. BECK has in this little book collected and set out in elementary form a considerable amount of information useful to the microscopist. The optics of the instrument are described in a simple manner ...

As early as the 4 th century AD, people had discovered the basic concept of an optical lens, and by the 13 th century, they were already using glass lenses to improve their eyesight and to magnify ...

Small modifications to an ordinary optical microscope have helped turn it into a powerful instrument that can be used for studying complex cellular biology in real time at the nanoscale level. And ...

(Nanowerk News) Researchers at the National Institute of Standards and Technology (NIST) and their collaborators have developed a way to retrofit the transmission electron microscope -- a ...

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 ...

Light microscopy is used to make small structures and samples visible by providing a magnified image of how they interact with visible light, e.g., their absorption, reflection and scattering. This is ...

Researchers have developed a way to retrofit the transmission electron microscope -- a long-standing scientific workhorse for making crisp microscopic images -- so that it can also create high-quality ...
