Researchers detect coronavirus particles with 'slow light'

Despite all the bad news the COVID-19 pandemic brought upon the world, it has helped us gain a better perspective of our readiness to fend off highly contagious diseases. Rapid diagnostic test kits and PCR testing quickly ...

Deep insights into a living fungus

In order to examine tissues under the microscope, they usually have to be cut into thin slices. But it is impossible to analyze whole tissues or living organisms in this way. However, this is exactly what two Mexican research ...

Vortex microscope sees more than ever before

Understanding the nitty gritty of how molecules interact with each other in the real, messy, dynamic environment of a living body is a challenge that must be overcome in order to understand a host of diseases, such as Alzheimer's.

When light loses symmetry, it can hold particles

Optical tweezers use light to immobilize microscopic particles as small as a single atom in 3D space. The basic principle behind optical tweezers is the momentum transfer between light and the object being held. Analogous ...

Integrated photonics meets electron microscopy

Scientists in Switzerland and Germany have achieved efficient electron-beam modulation using integrated photonics—circuits that guide light on a chip. The experiments could lead to entirely new quantum measurement schemes ...

Optical microscope

The optical microscope, often referred to as the "light microscope", is a type of microscope which uses visible light and a system of lenses to magnify images of small samples. Optical microscopes are the oldest and simplest of the microscopes. However, new designs of digital microscopes are now available which use a CCD camera to examine a sample and the image is shown directly on a computer screen without the need for expensive optics such as eye-pieces. Other microscopic methods which do not use visible light include scanning electron microscopy and transmission electron microscopy.
