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 ...

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 ...

A Korean research team has developed a near-field scanning optical microscope technology capable of observing structures as small as 50 nanometers (5/100,000,000 m). According to the Institute for ...

Overcoming the resolution limit in a light microscope of around half a wavelength of light (about 250 nanometers) is one of ...

A new x-ray microscopy technique permits observation of molecular-scale features less than a nanometer in height. Developed by scientists at the U.S. Department of Energy's Argonne (IL) National ...

Most conventional light microscopes have a resolution of 200 nanometers – this means that imaged objects which are any closer together won't be seen as separate items. A new high-tech microscope slide ...

Cell division, or the process of how daughter cells emerge from a mother cell, is fundamental to biology. Every cell inherits the same protein and DNA building blocks that make up the cell it ...

Over the last two decades, microscopy has seen unprecedented advances in speed and resolution. However, cellular structures are essentially three-dimensional, and conventional super-resolution ...

Functional principle of the STED-4Pi-Microcope: The interference of both red light pulses to a common focal point and the fluorescent excitation through the STED feeds the fluorescent point along the ...
