Energy Transfer Among Fluorescent Molecules Dispersed in Thin Films of Polymer or Protein (Rhodamine B, Sulforhodamine 101, Polyvinyl, Poly (Vinyl Alcohol) Bovine Serum Albumin, Time-Correlated Photon Counting, Lifetimes)
… if it can improve the effectiveness of proposed photochemical conversion systems by increasing their collection efficiency. This is similar to the coupling of the antenna pigment network of plants with the specialized photosynthetic conversion center.

Photochromic Molecular Materials for the Controlled Organization of Nanoparticles
… studies showed the azo nanospheres had a larger photochemical conversion then their corresponding thin films. These nanoobjects were then successfully coated with gold nanoparticles by using azo compounds with dithiane or thioacetate ligands that are known to complex gold. The hybrid structure …

Development of Liquid Chromatography Mass Spectrometry technique for evaluation and differentiation of plant derived isomers
… compounds are imperative. Herein, UV-induced photochemical conversion of cinnamic acid containing molecules is presented as a feasible means to diversify the number of bioactive metabolites in plant extracts. Naturally, UV rays from sunlight were shown to result in the formation of geometrical …

A photochemical method for the detection of cytosine modifications in DNA
… describes the discovery and development of a photochemical treatment that alters the hydrogen bonding pattern of 5-carboxycytosine to a uracil analogue. The photochemical conversion is selective for the unique carboxylate functionality of 5-carboxycytosine over other canonical and modified …

Design and applications of 4-yl-(methyl)coumarins and their derivatives
… due to the long exposure times required for full conversion and the reactive byproducts that form upon UV exposure. Another photofuse, known as the 4-yl-(methyl)coumarin, is of particular interest because of its rapid photochemical response, lack of reactive products upon UV exposure, and many …

Enzymology And Medicinal Chemistry Of N5-Carboxyaminoimidazole Ribonucleotide Synthetase : A Novel Antibacterial Target
… de novo purine biosynthesis, catalyzes the conversion of aminoimidazole ribonucleotide (AIR) to N5-CAIR. To date, this enzyme has been observed only in microorganisms, and thus, it represents an ideal target for antimicrobial drug development. Here we report structural and functional studies …

Light-induced modulation of DNA recognition by the Rad4/XPC damage sensor protein.
How various macromolecules come together to form specific biological complexes and how the assembly/disassembly of such complexes are regulated are key to understanding any biological process. Characterization of such dynamical processes is challenging as it necessitates means to rapidly and …
