By engineering a virus that Belcher has worked with for years, the team was able to get it to bond with multiple synthetic chromophores -- or, in this case, organic dyes.
The skin chromophore maps are calculated from the four spectral images, and the perfusion map and fluorophore distribution map--from the video-images taken at green and ultraviolet illumination of the skin, respectively.
Among the organic NLO chromophores, pyrazolines embedded in polymer show good optical properties, such as polarization, color change, fluorescent complex formation, polymorphism, molecular refraction and photochromism behavior.
Despite its widespread use, however, mRFP1 had several limitations, including incomplete chromophore maturation, relatively low brightness, and fast photobleaching during imaging experiments.
They create opaque chromophores (filters) on the surface of the skin which guard against potential damage, but remember that you should not substitute SPF protection for a self-tanning product.

Other subjects explored include hydrogen bonding effects on the photochemistry of chromophores in solution, photochemical generation of silicon-centered radicals and their reactions, and photochemical processes at the air-water interface of atmospheric droplets.
This work applies the measurement model to the measurement of absorbance in mixtures of microspheres and chromophores and to a suspension of microalgae.
During his doctoral research, Kevin investigated photo-responsive polymer systems based on azobenzene chromophores, and the mechanisms by which these polymers could be surface patterned by exposure to an interference pattern of light.
