This efficient movement of excitons has one key requirement: The chromophores have to be arranged just right, with exactly the right amount of space between them.
Then map thresholding is applied; the algorithm calculates all image regions, where the concentration of chromophores exceeds the specific threshold value.
This composite also contains a light-absorbing chromophores which absorb light from the interference pattern, creating localized hot spots.
NDI chromophores have a tendency to undergo self-assembly in polar media as the result of increased hydrophobic effects.
The science of NIRS hinges on some of the fundamental principles of pulse oximetry as they relate to the transmission of light through living tissues and the absorption of light by tissue chromophores (naturally occurring compounds that absorb light [e.
