Using 'dark channel' fluorescence, scientists can explain how biochemical substances carry out their function Spectroscopic techniques are among the most important methods by which scientists can look inside materials. They exploit the interaction of light waves with a given sample. Now, using X-ray absorption spectroscopy, researchers from Helmholtz-Zentrum Berlin fr Materialien und Energie (HZB) have observed the moving of electric charges from solute to solvent "“ so-called electron...

By swapping out one specific hydrogen atom for an isotope twice as heavy, researchers have increased the shelf life and detection ability of fluorescent probes that are essential to studying a variety of inflammatory diseases, including cancer and atherosclerosis. The probes detect and measure reactive oxygen species, which play an important role in disease processes. "By replacing a hydrogen atom with a deuterium atom during the synthesis of several fluorescent probes, we increased the...

Counterfeit products create losses in the billions each year. Beside the economic damages, all too often additional risks arise from the poor materials and shoddy workmanship of "knock-off artists". Yet with the aid of fluorescing dyes, materials can be individually tagged and identified with certainty. For quite some time now, product piracy has been affecting more than just consumer goods, like watches and designer clothing. The producer industry also has to combat bogus and qualitatively...

Scrutinizing a single molecule for more than a few milliseconds used to require effectively "stapling" it down, inhibiting its normal behavior. Now, using a technique recently developed in their lab, Stanford chemists have for the first time confined a protein (one involved in photosynthesis), observed its behavior for more than a second and learned things about it that could influence solar energy technology and biofuels. For the first time, researchers have been able to confine and study an...

Efficient identification of drug candidates The search for new therapeutic agents is time-consuming and expensive. Pharmaceutical companies may have to screen thousands of compounds for the ability to bind a target molecule before they hit upon a promising drug candidate. A group of Biophysicists at LMU Munich led by Professor Dieter Braun, a member of the Cluster of Excellence "Nanosystems Initiative Munich" (NIM), and a partner in NanoTemper (an LMU spin-off), have now developed a unique...

A team of Harvard chemists led by X. Sunney Xie has developed a new microscopic technique for seeing, in color, molecules with undetectable fluorescence. The room-temperature technique allows researchers to identify previously unseen molecules in living organisms and offers broad applications in biomedical imaging and research. The scientists' results are published in the Oct. 22 issue of Nature. Partial funding for the project was provided by the National Science Foundation (NSF)....
