Thus, the chromophores attached to two fused rings of five-membered heteroaromatic, such as substituted triazolo[3,4-b]thiadiazole heterocycle as shown in Fig.
While UV/Vis detection can easily identify some impurities and other compounds present in a sample, challenges arise with selectivity and identification of impurities that do not have inherent chromophores or vary in response factors (such as extinction coefficients).
Chromophores competition is highly reduced, which enables a high delivery of laser energy efficiently.
When irradiated with appropriate light, polymers containing azobenzene groups (azo polymers for short) will show different photoresponsive properties attributing to the reversible photoinduced trans-cis isomerization of the azo chromophores [30-33].
These new GPCRs appear to bind the same chromophores as opsins (11 -cis and all-trans retinal) but do so using amino acids at different sites in their binding pockets.
Diamine Schiff bases are different from monoamine Schiff bases in having two chromophores bridged by a methylene chain in a molecule, and thus the mutual interactions between the chromophores appears to affect their chemical and physical properties.
At this point, the aforementioned device, which takes into account the scattering of tissue, is to determine the concentration of chromophores (or optical absorbers) due to attenuated light strikes to the superficial layer of tissue.
The company's flagship product is the Zenascope, a patent-protected, photonic system that non-destructively measures dominant tissue chromophores (such as oxygenated hemoglobin, deoxygenated hemoglobin and beta-carotene) as well as changes in cellular morphology and density.
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.
Laser function is achieved through absorption of its energy on chromophores. In surgery, the most often used chromophores are hemoglobin and water.
The tourmaline chromophores Ti, V, Cr, Mn and Fe were all present in minor amounts, with much more V in the darker green areas, together with somewhat higher Ti and Cr concentrations.
