It’s Explosive! New Sensor Technology Patented

11.03.2004


New technology patented by researchers at the University of Wales, Bangor could lead to the development of ultra-sensitive sensors able to detect the presence of explosive materials. The sensors will have many security and military applications including being developed for use in the war against terrorism.



It is the innovative collaboration of molecular biology and chemistry that has enabled the team to develop the novel sensor technology ‘nano-dog’ to be developed to commercial prototype.

Much as the glucose pens used by diabetics employ enzymes to test blood-sugar levels, this complex high-tech sensor uses uniquely adapted and patented enzymes to detect the presence of explosive materials.


Some bacteria contain enzymes which are able to chemically modify many of the commonly used explosives. These bacteria have been used, particularly in the USA, to clean up land contaminated by munitions. The enzymes within the bacteria convert the explosives molecules to less toxic products, cleaning the contamination in the process. In this new process some of these enzymes have been purified from the bacteria and subjected to genetic modification. This modification has enabled the enzymes to adhere to the surface of an electrode sensor, where they remain active. There, they can trigger an electrical signal when activated by the presence of minute amounts of explosives molecules.

Chris Gwenin has been developing the project under the close guidance of Dr Maher Kalaji of the University’s Department of Chemistry and Prof Peter Williams of the School of Biological Sciences. He has been employed under a CASE Studentship, working with University spin-off company, Trwyn, who are now moving towards developing a prototype explosives detector to commercialize the technology.

“The project has moved forward at a tremendous pace, having reached a stage where we are able to patent our unique technology within 18 months of commencement,” said Dr Maher Kalaji. “The collaboration of expertise is what has led to the success. Crucial to the success of the project so far has been the unique combination of expertise from two discrete areas of molecular science. The success has also been aided by Chris Gwenin’s ability to develop new skills and expertise quickly,” commented Dr Maher Kalaji.

Commenting on the development, Professor Roy Evans, Vice-Chancellor of the University, said, “This is what is so exciting about research developments in higher education. The close collaboration of experts within different disciplines can take us to new ground. We have at Bangor a unique combination of expertise and I wish the company every success in taking this project forward commercial development.”

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
