Diagnosing cancer and selecting the appropriate therapy depend crucially on how well experts understand the processes in tumors at the microscopic level. Central to this is understanding how cells in ...

A team of researchers at the Departments of Physical Chemistry and Organic Chemistry of the University of Malaga and The ...

In present-day bioanalytics, the selection of a detection method may have a major impact on the sensitivity, accuracy and ...

Last year, we celebrated 50 years since the first papers on fluorescence correlation spectroscopy (FCS) were published. It ...

Biologists are very interested in how proteins, lipids and other compounds are organized and interact in systems. Very few organizational details can be gained by using standard transmission-based ...

Fluorescence is the process by which a photon is absorbed, and another of slightly lower energy, and therefore longer wavelength, is subsequently emitted. Under normal circumstances, the electrons of ...

Light microscopy does much what the name implies: visible light and magnifying lenses are used to view small objects. Light microscopes are the oldest form of higher quality imaging devices, dating ...

XRF relies on the emission of secondary X-rays from a material when irradiated with primary X-rays. Each element emits ...

Scientists can monitor biomolecular processes in live tissue by noninvasive optical methods, such as fluorescence imaging. However, the fluorescent dyes used for that purpose are often rather unstable ...

UV light makes it possible to see intricate structures of fossils that are barely visible in normal daylight. This method has often been used on the fossilized seashells from the Earth's current ...
