Technische Universität München Dr. Wilhelm Auwärter and his team are working on a research project to develop tiny flat molecule tapes at the Department of Physics of Technische Universität München (TUM). These structures could find versatile applications. Via direct coupling on a silver surface, the scientists successfully formed dimers and short chains of porphine molecules without contaminating by-products. Porphyrin molecules are essential to many biological processes, such as...

The Scripps Research Institute Scientists from the Florida campus of The Scripps Research Institute (TSRI) have discovered a surprising new role for a pair of compounds—which have the potential to alter circadian rhythm, the complex physiological process that responds to a 24-hour cycle of light and dark and is present in most living things. At least one of these compounds could be developed as a chemical probe to uncover new therapeutic approaches to a range of disorders, including...

The compound can be toggled back and forth between its aromatic and anti-aromatic states, as well as to a never before seen intermediate state By synthesizing a stable "antiaromatic" compound, as well as a never before seen intermediate version of that compound, chemists at The University of Texas at Austin have written an important new chapter in the story of modern chemistry. The research was done in collaboration with an international roster of colleagues from Yonsei University in...

It is helpful "” even life-saving "” to have a warning sign before a structural system fails, but, when the system is only a few nanometers in size, having a sign that's easy to read is a challenge. Now, thanks to a clever bit of molecular design by University of Pennsylvania and Duke University bioengineers and chemists, such warning can come in the form of a simple color change. The study was conducted by professor Daniel Hammer and graduate students Neha Kamat and Laurel Moses...

New insights from the nano world The mechanism for binding oxygen to metalloporphyrins is a vital process for oxygen-breathing organisms. Understanding how small gas molecules are chemically bound to the metal complex is also important in catalysis or the implementation of chemical sensors. When investigating these binding mechanisms, scientists use porphyrin rings with a central cobalt or iron atom. They coat a copper or silver support surface with these substances. An important...

DULUTH, Ga., May 8 /PRNewswire/ -- Metametrix Clinical Laboratory ( http://www.metametrix.com/ ), a leader in nutritional and metabolic testing, announced the introduction of the urinary Neopterin/Biopterin Profile. This latest testing profile measures the oxidative products of tetrahydrobiopterin (BH4). Neopterin and biopterin are by-products of the redox reactions involving tetrahydrobiopterin (BH4). Restricted BH4 availability has been suggested as an etiologic factor in neurological...

HOUSTON "“ (Oct. 7, 2005) -- A research team led by scientists at The University of Texas Medical School at Houston has determined the structure of an enzyme that when defective causes an inherited disease that afflicts sufferers with severe abdominal pain, psychiatric symptoms, skin fragility, and light sensitivity. "Unless prompt and appropriate treatment is given, hereditary coproporphyria can very quickly turn into a life-threatening medical emergency," said C. S. Raman, Ph.D.,...
