Nanowire-based sensors offer improved detection of volatile organic compounds


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


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


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


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 ...


Nitto Denko to Start-up Prototyping Centre in Singapore Research Institute


Nitto Denko Asia Technical Centre (NAT) will be expanding its Singapore base to include a prototyping centre in Singapore. The centre will be pioneered at A*STAR's Institute of Materials Research and Engineering (IMRE) under a unique Lab-in-RI programme. NAT can leverage on existing ...


UV-transparent coating for image sensors


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 ...


SPECIM and Forschungszentrum Jülich sign contract for development of advanced hyperspectral imagers for vegetation research


SPECIM, Spectral Imaging Ltd announced a new project with Forschungszentrum Jülich in Germany. The first target of the HyPlant project is to develop a new-generation push-broom hyperspectral imager capable of collecting seamless VNIR and SWIR data from 380 to 2500 nm in a single, compact ...


Out-sniffing bomb-sniffing dogs

Tel Aviv University researcher leads development of swift, small, highly reliable sensor to detect explosives


Dogs have long been called man's best bomb detector –– until now. A Tel Aviv University scientist leads a research team that has developed a powerful electronic sensor to detect multiple kinds of explosives –– including those used in the recent Yemeni bomb threat. Based on nanotechnology ...


Measuring the electrical properties of nano-crystals

UK scientists help to create standards for measuring electric materials on the nanoscale


The UK's National Physical Laboratory (NPL) is working to provide more reliable measurement of the electrical properties of materials used in nanotechnology – which could lead to much more accurate devices in the future. Scanning probe microscopy (SPM) won the Nobel Prize in 1986. It uses a ...


Sniffing out shoe bombs: A new and simple sensor for explosive chemicals


University of Illinois chemists have developed a simple sensor to detect an explosive used in shoe bombs. It could lead to inexpensive, easy-to-use devices for luggage and passenger screening at airports and elsewhere. Triacetone triperoxide (TATP) is a high-powered explosive that in recent ...
