Most cell signals are chemical in nature. For example, prokaryotic organisms have sensors that detect nutrients and help them navigate toward food sources. In multicellular organisms, growth ...

Identifying various types of molecules and cells is a crucial step ... a version of Raman spectroscopy that produces stronger signals than conventional, spontaneous Raman spectroscopy, a ...

Accordingly, by means of an EdU treated cell, we succeeded in the detection of Raman scattering derived from the vibration of the alkyne by Raman microscope, and were able to observe the state of the ...

Understanding the behavior of the molecules and cells that make ... However, the Raman light that comes from biological samples is very weak, so the signal can often get swamped by the background ...

Unlike erbium-doped fiber amplifiers (EDFAs), which boost wavelengths in the 1530-1610 nm range, a Raman amplifier can increase the signal strength of any wavelength by pumping at 13THz more than ...

WITec's alpha300 Ri inverted confocal Raman imaging microscope facilitates 3D chemical characterization from a new angle. The inverted beam path of the alpha300 Ri microscope preserves all the ...
