A global team of researchers headed by Rob Ameloot and Ivo Stassen from KU Leuven have studied the possibility of detecting nerve gas and pesticides in extremely low concentrations.
A team of MIT researchers have created economical chemical sensors using chemically altered carbon nanotubes, that facilitate smartphones or other wireless devices to sense trace quantities of poisonous gases. With the aid of these sensors, the researchers aim to build lightweight, low-cost radio-frequency identification (RFID) badges that can be applied for individual security and safety.
A study is under progress in the Clemson University to develop a new sensor. This sensor is being designed to aid in the detection of destructive weapons across the world, in order to protect the world from rogue nations and terrorists.
Many cancers could be successfully treated if the patient consulted the doctor sufficiently early. But how can a developing cancer be detected if it doesn't give rise to any symptoms? In the near future, suitably early diagnosis could be provided by simple and cheap chemical sensors - thanks to special recognizing polymer films developed at the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw.
Trace contaminants in water are often measured by taking samples from the environment to a lab for analysis, which can lead to inaccurate results due to delayed and irregular sample collection or long-transportation and handling times. Thus, techniques enabling in-situ or real-time measurements of water contaminants are no doubt one of the major steps towards effective control of water quality.
Implant Sciences Corporation, a leading manufacturer of explosives trace detection (ETD) solutions for aviation and security applications, today announced that it has shipped approximately $1 million of its QS-B220 desktop explosives and drugs trace detectors and its QS-H150 handheld explosives trace detectors.
Some biochemistry laboratories fashion proteins into complex shapes, constructing the DNA nanotechnological equivalent of Baroque or Rococo architecture. Yamuna Krishnan, however, prefers structurally minimalist devices.
Alkane fuel is a key ingredient in combustible material such as gasoline, airplane fuel, oil -- even a homemade bomb. Yet it's difficult to detect and there are no portable scanners available that can sniff out the odorless and colorless vapor.
Original drawings and sketches from Walt Disney Animation Studio’s more than 90-year history — from Steamboat Willie through Frozen — traveled internationally for the first time this summer. This gave conservators the rare opportunity to monitor the artwork with a new state-of-the-art sensor. A team of researchers report today that they developed and used a super-sensitive artificial “nose,” customized specifically to detect pollutants before they could irreversibly damage the artwork.
Instead of a pan and a pick ax, prospectors of the future might seek gold with a hand-held biosensor that uses a component of DNA to detect traces of the element in water.
