Bimetallic nanoantenna separates colors of light

30-Sep-2011

Researchers at Chalmers University of Technology have built a very simple nanoantenna that directs red and blue colours in opposite directions, even though the antenna is smaller than the wavelength of light. The findings – published in the online journal Nature Communications – can lead to ...

Sensirion moves into a new production building in Switzerland

03-Aug-2011

Sensirion inaugurated its new production building in mid-July 2011. After eight months of construction, the newly purchased production plant in Stäfa, Switzerland, situated just a few hundred meters from the main building, was ready for occupancy. With the purchase and renovation of the building, ...

The secret behind NIST's new gas detector? Chirp before sniffing

16-May-2011

Trace gas detection, the ability to detect a scant quantity of a particular molecule — a whiff of formaldehyde or a hint of acetone — in a vast sea of others, underlies many important applications, from medical tests to air pollution detectors to bomb sniffers. Now, a sensor recently developed at ...

New material could improve safety for first responders to chemical hazards

Carbon nanofibers assembled into photonic crystals change color as activated charcoal filters become saturated with dangerous vapors

03-May-2011

A new kind of sensor could warn emergency workers when carbon filters in the respirators they wear to avoid inhaling toxic fumes have become dangerously saturated. In a recent issue of the journal Advanced Materials, a team of researchers from the University of California, San Diego and Tyco ...

New biosensor microchip could speed up drug development, Stanford researchers say

26-Apr-2011

Stanford researchers have developed a new biosensor microchip that could significantly speed up the process of drug development. The microchips, packed with highly sensitive "nanosensors," analyze how proteins bind to one another, a critical step for evaluating the effectiveness and possible side ...

UV-transparent coating for image sensors

14-Feb-2011

Image sensors as used in cell phones are partially color-blind. This is because of their coating, which prevents UV light from passing through. CMOS chips have as a result not been suitable for spectroscopy up to now. A new production process makes the coating transparent – and the sensors ...
