Thus far, the best tools for imaging in live, whole animals have been far-red fluorescent proteins because both autofluorescence and light absorption by the animal's tissue are minimized at the ...

Fluorescent probes are molecules that absorb light of a specific wavelength and emit light of a different, typically longer, wavelength (a process known as fluorescence), and are used to study ...

By nature, each fluorescent dye exhibits a unique absorbance and emission spectra ... the concentration of a target is determined by the kinetic activity of the light absorbed and emitted by a ...
