http://www.physorg.com/chemistry-news/analytical-chemistry/ en-us PhysOrg.com provides the latest news on analytical chemistry Austrian researchers have successfully developed a new electrophoretic method for detecting MIRCERA(R) and other erythropoietins (EPO) in the blood. The technique, using SARCOSYL-PAGE, has specifically enhanced sensitivity for MIRCERA, but does not alter the performance characteristics of SDS-PAGE for detecting other EPOs. Details of this study, funded by a grant from the World Anti-Doping Agency (WADA), appear in the latest issue of Drug Testing and Analysis. http://www.physorg.com/news180162559.html Chemistry - Analytical Chemistry Wed, 16 Dec 2009 06:00:02 EST news180162559 There is more to the snowflake than its ability to delight schoolchildren and snarl traffic. http://www.physorg.com/news179416713.html Chemistry - Analytical Chemistry Mon, 07 Dec 2009 14:26:57 EST news179416713 (PhysOrg.com) -- Antonio Stradivari is the most famous instrument maker of all time. He was especially famous for his violins, which he produced in Cremona from about 1665 until his death in 1737. In particular, the legendary varnish on his instruments has fascinated musicians, violinmakers, historians, and chemists since the beginning of the 19th century -- inciting controversial speculation about "secret" ingredients. The use of analytical processes has allowed a team of scientists from various French and German institutions to shine a light on the mystery. http://www.physorg.com/news179148281.html Chemistry - Analytical Chemistry Fri, 04 Dec 2009 11:25:36 EST news179148281 A team at The Scripps Research Institute has made major strides in solving a problem that has been plaguing chemists for many years: how best to break carbon-hydrogen bonds and then to create new bonds to join molecules together. This problem is of great interest to the pharmaceutical industry, which currently relies on a method to accomplish this feat that is relatively inefficient and sometimes difficult to perform. http://www.physorg.com/news179148095.html Chemistry - Analytical Chemistry Fri, 04 Dec 2009 11:22:20 EST news179148095 Scientists may not be able to tell a good book by its cover, but they now can tell the condition of an old book by its smell. In a report in ACS' Analytical Chemistry, a semi-monthly journal, they describe development of a new test that can measure the degradation of old books and precious historical documents based on their smell. The nondestructive "sniff" test could help libraries and museums preserve a range of prized paper-based objects, some of which are degrading rapidly due to advancing age, the scientists say. http://www.physorg.com/news179002489.html Chemistry - Analytical Chemistry Wed, 02 Dec 2009 18:55:46 EST news179002489 (PhysOrg.com) -- A new study using solid-state NMR spectroscopy to analyze intact bone paves the way for atomic-level explorations of how disease and aging affect bone. The research by scientists at the University of Michigan is reported in the Dec. 2 issue of the Journal of the American Chemical Society. http://www.physorg.com/news178994090.html Chemistry - Analytical Chemistry Wed, 02 Dec 2009 17:20:01 EST news178994090 (PhysOrg.com) -- The copper sequestering drug tetrathiomolybdate (TM) has been shown in studies to be effective in the treatment of Wilson disease, a disease caused by an overload of copper, and certain metastatic cancers. That much is known. Very little, however, is known about how the drug works at the molecular level. http://www.physorg.com/news178458552.html Chemistry - Analytical Chemistry Thu, 26 Nov 2009 14:00:03 EST news178458552 GE Global Research, the technology development arm for the General Electric, today announced a $2 million award from the National Institute of Environmental Health Sciences to develop wearable RFID sensors to alert people to the presence of environmental chemical agents in the air and sample exhaled breath to serve as an early indicator of disease. http://www.physorg.com/news177955412.html Chemistry - Analytical Chemistry Fri, 20 Nov 2009 16:30:03 EST news177955412 IBM scientists have created a one-step point-of-care-diagnostic test, based on an innovative silicon chip, that requires less sample volume, is significantly faster, portable, easy to use, and can test for many diseases, including one of world's leading causes of death, cardiovascular disease*. The results are so quick and accurate that a small sample of a patient's serum or blood, could be tested immediately following a heart attack, to enable the doctor to quickly take a course of action to help the patient survive. http://www.physorg.com/news177880059.html Chemistry - Analytical Chemistry Thu, 19 Nov 2009 19:08:24 EST news177880059 The goal of an integrated, miniaturized laboratory analysis system, also known as a "lab-on-a-chip," is simple: sample in, answer out. However, researchers wanting to use these microfluidic devices to analyze complex solutions containing particulates or other contaminating materials often find that the first part of the process isn't so easy. Effective sample preparation from these solutions can be laborious, expensive and time-consuming, involving complicated laboratory methods that must be performed by skilled technicians. This can significantly diminish the benefits associated with using miniaturized analytical techniques. Recent work at the National Institute of Standards and Technology could help change that. http://www.physorg.com/news177763391.html Chemistry - Analytical Chemistry Wed, 18 Nov 2009 11:00:01 EST news177763391 (PhysOrg.com) -- Amid the on-going controversy over the safety of mercury-containing dental fillings, a University of Saskatchewan research team has shed new light on how the chemical forms of mercury at the surface of fillings change over time. http://www.physorg.com/news177184158.html Chemistry - Analytical Chemistry Wed, 11 Nov 2009 17:58:21 EST news177184158 Scientists may not be able to tell a good book by its cover, but they now can tell the condition of an old book by its odor. In a report published in the American Chemical Society's Analytical Chemistry they describe development of a new test that can measure the degradation of old books and precious historical documents on the basis of their aroma.

EphA4 functions by binding to ephrin ligands, cell surface proteins which sit on opposing cells. The signalling cascades which result from this contact direct cells to move in a particular direction, to the right place in the body. This is critical in the development of the nervous system, and has also been linked with the suppression of melanoma tumours. http://www.physorg.com/news175521338.html Chemistry - Analytical Chemistry Fri, 23 Oct 2009 13:20:01 EST news175521338 (PhysOrg.com) -- A team of Harvard chemists led by X.

The room-temperature technique allows researchers to identify previously unseen molecules in living organisms and offers broad applications in biomedical imaging and research. http://www.physorg.com/news175513649.html Chemistry - Analytical Chemistry Fri, 23 Oct 2009 10:48:18 EST news175513649 An abundant greenhouse gas could someday help clean up the earth. Converting methane to liquid methanol could produce clean, low-cost fuel and prevent the potent greenhouse gas from entering the atmosphere. Exploiting methane in this way could also produce a hydrogen source for fuel cells and yield other industrial applications. http://www.physorg.com/news175434422.html Chemistry - Analytical Chemistry Thu, 22 Oct 2009 13:10:01 EST news175434422 It is very difficult to predict whether a cancer drug will help an individual patient: only around one third of drugs will work directly in a given patient. Researchers at the Heinz Nixdorf Chair for Medical Electronics at the Technische Universitaet Muenchen (TUM, Germany) have developed a new test process for cancer drugs. With the help of microchips, they can establish in the laboratory whether a patient's tumor cells will react to a given drug. This chip could help in future with the rapid identification of the most effective medication for the individual patient. http://www.physorg.com/news175412440.html Chemistry - Analytical Chemistry Thu, 22 Oct 2009 06:50:02 EST news175412440 (PhysOrg.com) -- A chemist at NASA's Jet Propulsion Laboratory in Pasadena, Calif., has developed a technology intended to rapidly assess any presence of microbial life on spacecraft.
