Start-up company prepares to commercialize novel detector for medical, military applications (10/30/2009)

Start-up company prepares to commercialize novel detector for medical, military applicationsPAIR Technologies, a start-up company established by University of Delaware researchers and a former DuPont scientist, is preparing to commercialize a high-precision detector -- a planar array infrared spectrograph -- that can identify biological and chemical agents in solids, liquids and gases, in quantities as small as an atom, and in less than a second. ...> Full Article



Designer molecule detects tiny amounts of cyanide, then glows (10/23/2009)

Designer molecule detects tiny amounts of cyanide, then glowsA small molecule designed to detect cyanide in water samples works quickly, is easy to use, and glows under ultraviolet or "black" light. Although the fluorescent molecule is not yet ready for market, its Indiana University Bloomington creators report in the Journal of the American Chemical Society (now online) that the tool is already able to sense cyanide below the toxicity threshold established by the World Health Organization. ...> Full Article



Tracing ultra-fine dust (10/6/2009)

Tracing ultra-fine dustLimit values for fine dust emissions are based on total particle weight. It is the ultra-fine particles, however, that are particularly harmful to health. A new technique separates them by size and identifies their composition -- directly where they arise. ...> Full Article



Opto-electronic nose sniffs out toxic gases (9/15/2009)

Opto-electronic nose sniffs out toxic gases Imagine a polka-dotted postage stamp that can sniff out poisonous gases or deadly toxins simply by changing colors. As reported in the September 13 issue of the journal Nature Chemistry, Kenneth Suslick and his team at the University of Illinois have developed an artificial nose for the general detection of toxic industrial chemicals that is simple, fast and inexpensive -- and works by visualizing odors. ...> Full Article



Mysterious charge transport in self-assembled monolayer transistors unraveled (8/16/2009)

Mysterious charge transport in self-assembled monolayer transistors unraveledAn international team of researchers from the Netherlands, Russia and Austria discovered that monolayer coverage and channel length set the mobility in self-assembled monolayer field-effect transistors. This opens the door to extremely sensitive chemical sensors that can be produced in a cost-effective way. The research was done at Philips Research Eindhoven and Eindhoven University of Technology. The findings were published as an advanced online publication in Nature Nanotechnology. ...> Full Article



Chemists explain the switchboards in our cells (8/6/2009)

Chemists explain the switchboards in our cellsOur cells are controlled by billions of molecular "switches" and chemists at UC Santa Barbara have developed a theory that explains how these molecules work. Their findings may significantly help efforts to build biologically based sensors for the detection of chemicals ranging from drugs to explosives to disease markers. ...> Full Article


Researchers: Molecular forklifts overcome obstacle to 'smart dust' (1/20/2009)

Algae is a livid green giveaway of nutrient pollution in a lake. Scientists would love to reproduce that action in tiny particles that would turn different colors if exposed to biological weapons, food spoilage or signs of poor health in the blood. ...> Full Article


Shape changes in aroma-producing molecules determine the fragrances we detect (12/27/2008)

Shakespeare wrote "a rose by any other name would smell as sweet." But would it if the molecules that generate its fragrance were to change their shape? That's what Dr. Kevin Ryan, Assistant Professor of Chemistry at the City College of New York and collaborators set out to investigate. ...> Full Article
