To use a light microscope to examine animal or plant cells. To make observations and draw scale diagrams of cells. Turn the coarse focus so that the stage is as close to the objective lens as possible ...

Light microscopy is used to make small structures and samples visible by providing a magnified image of how they interact with visible light, e.g., their absorption, reflection and scattering. This is ...

Using a “spooky” phenomenon of quantum physics, Caltech researchers have discovered a way to double the resolution of light microscopes. In a paper appearing in the journal Nature Communications, a ...

Space to play or pause, M to mute, left and right arrows to seek, up and down arrows for volume. Dutch scientist Antony van Leeuwenhoek is credited with inventing the light or optical microscope ...

QIScope: When imaging low protein levels in live cells on the high-sensitivity QIScope, bioluminescence (blue) significantly outperforms fluorescence (green). (Courtesy: Ruyu Ma - Helmholtz Munich) A ...

Electron microscopes are used to visualize the structure of solids, molecules, or nanoparticles with atomic resolution. However, most materials are not static. Rather, they interact, move, and reshape ...

A team of researchers has developed the first transmission electron microscope which operates at the temporal resolution of a single attosecond, allowing for the first still-image of an electron in ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. Electron microscopy has existed for nearly a century, but a record ...

Fundamentally, a microscope comprises two subsystems: an illumination system to illuminate the sample and an imaging system that produces a magnified image of the light that has interacted with the ...
