Sensors Manufacturers Aim to Develop Miniaturized, High-Performance, Yet Low-cost Sensors, Notes Frost & Sullivan

The global demand for highly selective, sensitive and cost-effective sensors is rising

30-Nov-2011 - Over the years, the basic principle of sensor operation has remained unchanged and so has the working methodology of advanced sensors. What has changed, however, is the type of materials and sensing principles employed in the manufacture of new sensors. Sensing technologies are expected to go ...

Graphene foam detects explosives, emissions better than today's gas sensors

Rensselaer Polytechnic Institute engineering researchers overcome decade-old hurdle hampering development of nanostructure-based gas sensors

30-Nov-2011 - A new study from Rensselaer Polytechnic Institute demonstrates how graphene foam can outperform leading commercial gas sensors in detecting potentially dangerous and explosive chemicals. The discovery opens the door for a new generation of gas sensors to be used by bomb squads, law enforcement ...

MIT: Tiny stamps for tiny sensors

New glass stamp may make cheaper, more precise biosensors

21-Oct-2011 - Advances in microchip technology may someday enable clinicians to perform tests for hundreds of diseases — sifting out specific molecules, such as early stage cancer cells — from just one drop of blood. But fabricating such “lab-on-a-chip” designs — tiny, integrated diagonistic sensor arrays on ...

Tecan and Attana extend distribution agreement

13-Oct-2011 - Tecan and Attana AB have announced an extended distribution agreement under which Tecan will distribute Attana's label-free biosensor instruments and quartz crystal microbalance (QCM) assay technology in Europe. This collaboration covers the Attana 100, Attana 200 and Cell 200 instruments, as ...

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, ...

Materials: The first graphene-based chiral sensor

03-Aug-2011 - A reusable, natural and cheap amylose-functionalised graphene sensor was developed for highly sensitive and visual fluorescent chiral sensing by a team in China.The team found that the sensor’s detection sensitivity toward L-tryptophan was over 100 times higher than that of recently reported ...

Nanowire-based sensors offer improved detection of volatile organic compounds

30-Jun-2011 - A team of researchers from the National Institute of Standards and Technology (NIST), George Mason University and the University of Maryland has made nano-sized sensors that detect volatile organic compounds—harmful pollutants released from paints, cleaners, pesticides and other products—that ...

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 ...
