A team of researchers has integrated tiny detectors capable of counting individual photons on computer chips. These detectors, called "single-photon avalanche diodes (SPAD)," act like mini Geiger counters, producing a "tick" each time a photon is detected. The researchers present their findings in Applied Physics Letters, a journal published by the American Institute of Physics. "In the past, making these detectors required specialized processes, but recently there has been tremendous...

Researchers first to use tiny transistors to detect the kinetics of DNA-DNA binding An interdisciplinary team from Columbia University that includes electrical engineers from Columbia's Engineering School, together with researchers from the University's departments of Physics and Chemistry, has figured out a way to study single-molecule interactions on very short time scales using nanoscale transistors. In a paper to be published online January 23 in Nature Nanotechnology, they show how, for...

A new approach to building an "artificial nose" "“ using fluorescent compounds and DNA "“ could accelerate the use of sniffing sensors into the realm of mass production and widespread use, say Stanford chemists. If their method lives up to its promise, it could one day detect everything from incipiently souring milk to high explosives.By sticking fluorescent compounds onto short strands of the molecules that form the backbone of DNA, the researchers have produced tiny sensor...

A new paper by University of Notre Dame physicist Boldizsár Jank³ and colleagues offers an important new understanding of an enduring mystery in chemical physics. More than a century ago, at the dawn of modern quantum mechanics, the Noble Prize-winning physicist Neils Bohr predicted so-called "quantum jumps." He predicted that these jumps would be due to electrons making transitions between discrete energy levels of individual atoms and molecules. Although controversial in Bohr's...

Development Will Open New Avenues for Research Researchers from Carnegie Mellon University's Molecular Biosensor and Imaging Center (MBIC) are turning up the brightness on a group of fluorescent probes called fluoromodules that are used to monitor biological activities of individual proteins in real-time. This latest advance enhances their fluormodule technology by causing it to glow an order of magnitude brighter than typical fluorescent proteins. The new fluoromodules are five- to...

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...
