A nanoparticle "tattoo" as a glucose sensor that can be continuously monitored; a nose for your cellphone to sniff out airborne toxins; Biomagnetics Diagnostics Corp. introduces optical biosensor; and two years of competitively folding proteins with "foldit" at Games for Health 2010.
Nanotattoo monitors blood glucose, looks cool: Millions of people suffering from diabetes are forced to endure multiple finger pricks daily — an unpleasant practice that may impede compliance and which relies on its operator for consistency. Now, Drs. Paul Barone and Michael Strano at the MIT Dept. of Chemical Engineering are developing a new approach to glucose monitoring. Building on work they previously published in ACS Nano, the new technology employs a nanoparticle "tattoo" as a glucose sensor, which can then be continuously monitored by a device on the surface of the body.
A nose for your cellphone to sniff out airborne toxins: Cellphones may soon be able to detect carbon monoxide and other dangerous toxins found in gasoline and chemical warfare agents using a tiny silicon chip sensing system developed by researchers at UCSD and Rhevision Inc. Embedded within the silicon sensor are hundreds of separate spots that can change color in response to specific chemicals. By capturing the pattern of color changes using a new kind of supermacro lens, researchers at UCSD plan to create a versatile sensor small enough to fit into a cellphone that can recognize a wide variety of chemical hazards.
