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 ...

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 ...

A team has constructed an improved mid-infrared microscope, enabling them to see the structures inside living bacteria at the nanometer scale. Mid-infrared microscopy is typically limited by its low ...

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 ...

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 ...
