Beauty and grooming science evolves

...n Color and its Interaction with Cosmetic Foundation, Presented by Karen Kalla The optics of human skin are well understood, including how the skin's chromophore layers (melanin, hemoglobin, and collagen) generate reflectance in specific regions of the visible spectrum. However, how these phenomenon vary acro...

STAAR Surgical Forms Team of Leading Ophthalmic Surgeons to Study the Use of Collamer(R) Material for Accommodating Intraocular Lenses

...ition; it is a 100 percent pure collagen copolymer. Collamer is composed of a poly-HEMA based copolymer, a small amount of collagen and a UV-absorbing chromophore (light absorbing chemical). When fully hydrated, the Collamer lens material possesses a high water content concentrated at the surface of the lens. ...

Circadian Clocks Triggered Chemical Reactions may Be Behind Jet Lag

...ust after sunrise. They studied a protein called vivid, which contains a chromophore, a light-absorbing molecule. The researchers say that the chromophore captures a particle of light, and the captured energy from the light triggers a series of interactions that ultimately lead to conformational changes ...

Women's Skin Tone Influences Perception of Beauty, Health, Age

...on the surface and in underlying layers. This discoloration can be subtle or overt. We believe the judgment of facial skin age is influenced by uneven chromophore distribution and a decrease in light reflection,” says Grammer. ource-Newswise SRM ...

Chromophore in Biological News

Protein synthesis can be controlled by light, opening way for new scientific, medical applications

... The idea of "caged compounds" has been around for some 30 years. In the current application, the team attached a light-sensitive molecule called a chromophore to a bioactive molecule called an effector through a single covalent bond that inactivates the bioactive molecule. Exposing the caged compound to ligh...

In the nanoscale color detector, light strikes a chromophore and causes a conformational change in the molecule, which in turn causes a ...pothesis of how the chromophores were arranged on the nanotubes and how the chromophore isomerizations affected electronic properties of the devices. To constr...

ANALYSIS OF AMINO ACIDS BY REVERSED PHASE CHROMATOGRAPHY WITH PRECOLUMN DERIVATISATION AND UV/VISIBLE DETECTION

...ase sensitivity, their analysis normally includes a derivatisation step in which the amino acids react with a precursor to yield a strong UV/Visible chromophore or a fluorescent compound. Derivatisation can be performed before the chromatographic separation or after the separation step itself. In this ...

Fluorometric Protease Assays in the SpectraMax Gemini Microplate Spectrofluorometer: Example Using Caspase3 (MaxLine Application Note #35)

...eptide substrates. Enzyme selectivity is obtained by choosing a peptide sequence uniquely recognized by the catalytic site of a particular enzyme. The chromophore or fluorophore is attached near the peptides cleavage site and enzymatic activity is detected by the increase in color or fluorescence. Chromogenic as...

Time gated separation of lanthanide luminescence

...ed measurement of lanthanide systems. In this Application Note, two lanthanide complexes comprising an encapsulating complex with benzophenone antenna chromophore (L, see Fig. 1) and europium (Eu) or terbium (Tb) ions are investigated using time-gated spectroscopy with the FluoroMax -P. ...

Cytosolic expression of Green Fluorescent Protein (GFP) and its derivatives in the yeast Saccharomyces cerevisiae: Detection in vivo using the Varian Cary Eclipse

...ce then, a rapidly increasing variety of applications for GFP and its derivatives have been developed. Mutational studies of the chromophore and surrounding amino acids have produced new GFPs with altered excitation and emission spectra. These include blue (BFP), cyan (CFP), and ...
