Scientists have produced the world's most powerful optical microscope, which could help us understand the causes of many viruses and diseases. Scientists have produced the world's most powerful ...

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

Schematic of the transmission mode microsphere superlens integrated with a classical optical microscope. The spheres collect the near-field object information and form virtual images that can be ...

Left, a tissue sample dyed by traditional methods. Centre, a computed stain created from infrared–optical hybrid imaging. Right, tissue types identified with infrared data; the pink in this image ...

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 ...

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 ...

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 ...

Optical microscopy is a very useful technique to examine the appearance of a sample with greater detail, but there are some limitations that provide a boundary to its use in practice. Cross section of ...
