Microscopes have long been scientists’ eyes into the unseen, revealing everything from bustling cells to viruses and nanoscale structures. However, even the most powerful optical microscopes have been ...

For human researchers, it takes many years of work to discover new super-resolution microscopy techniques. The number of possible optical configurations of a microscope -- for example, where to place ...

Researchers have developed a new microscope that can visualize the optical response of surfaces at an unprecedented spatial resolution of one nanometer. This paves the way for optical microscopy of ...

Until today, skin, brain, and all tissues of the human body were difficult to observe in detail with an optical microscope, since the contrast in the image was hindered by the high density of their ...

What is the Diffraction Limit? The diffraction limit is a fundamental barrier in optical microscopy that sets the minimum size of features that can be resolved using conventional light microscopes. It ...

Confocal microscopy is a specialized fluorescence imaging technique that scientists use to acquire images at greater resolution than conventional microscopy. 1 In addition to scanning the lateral x ...

At its core, SPM operates on the principle of measuring interactions between a sharp probe and the surface of a material. As the probe scans across the surface, it detects variations in physical ...

Carbon nanotube architectures are used in numerous technologies because of their unique attributes. Raman spectroscopy can analyze a variety of carbon nanotube attributes, including tube diameter, ...

Drugs and fibers are among the materials collected in forensic and criminal laboratories. Some of these samples can be quite small, and light microscopes are frequently employed to examine evidence ...
