Multiphoton Microscope Observes Cell Membrane Action Date: October 23, 2003 Source: Cornell University Summary: In the past it was possible for theoreticians only to analyze the thermodynamic ...

Researchers have developed a new X-ray nanotomography microscope. Using their new system, they can reveal the structures on the smallest components of mammalian cells in three dimensions.

The new microscope delivers a high-resolution 3-D image of the entire cell in one step. This is an advantage over electron microscopy, in which a 3-D image is assembled out of many thin sections ...

This fluorescence light micrograph shows two important support cells (glial cells) of the human brain. The green splash is a microglial cell, which responds to immune reactions in the central nervous ...

Under a traditional, light-based microscope, it’s impossible to image something smaller than the wavelength of light that the microscope uses, which is around 250 nanometers, explains Brian ...

For example, using green light with a wavelength of 550 nm and an objective with a typical NA of 0.7, a standard light microscope can resolve features down to a limit of 0.61 × (550 nm)/0.7 ≈ 480 nm, ...

Now, a team from Helmholtz-Zentrum Berlin (HZB) have demonstrated a process called X-ray nanotomography, that can instantly obtain 3D images of cells in their almost natural state. SUBSCRIBE LOG IN ...

Researchers from the Oswaldo Cruz Foundation in Brazil have used a powerful electron microscope to capture photos of the exact moment the SARS-COV-2 virus takes over healthy cells ...

Using multiphoton three-dimensional microscopy, Cornell University biophysicists have achieved the first visualization of cell membrane sacs (vesicles) as they change shape.
