Application of micro and nanotechnologies in systems for the rapid detection of pesticides and pathogens

The III Hispano-French Conference on micro and nanotechnologies was held recently in Donostia-San Sebastián, one of the participants being AZTI- Tecnalia which presented part of its research carried out within the framework of the European GOODFOOD - Food Safety and Quality Monitoring with Microsystems programme

Being involved as it is in the field of micro and nanotechnologies, AZTI-Tecnalia is currently taking part in the validation of microsystems for their application in foodstuffs, collaborating in the development of improvements in the “BIO” detection system. Thus, microsystems for their use in the rapid detection of pesticides and pathogens, amongst others.

As regards pesticides, an assessment of a microsystem for determining atrazine and 2,4,6- trichlorophenol in wine samples was presented. Likewise, and with reference to the detection of pathogens, the work undertaken with a prototype for a portable sensor capable of simultaneously detecting Salmonella spp. and Listeria monocytogenes in fish and dairy products was presented – a system which considerably reduces the detection time for these infections.

Research work carried out on a microsystem for the quality control of foodstuffs and food safety, particularly fish, was presented. The fish sector above all requires sensitive methods that are able to report on the state of conservation of their products. Thus, part of the research work focused on the determination of volatile substance produced by fish products during their storage and on defining molecular markers capable of indicating the useful or end-life of the same.

Finally, AZTI-Tecnalia informed about the applications and risks of micro- and nanotechnologies in the food sector. It is predicted that these technologies, still emerging ones in the sector, will provide innumerable advantages in the quality control of foodstuffs and food safety (design and development of intelligent packaging, new intelligent systems of traceability, development of nanoparticles with bactericidal action, new functional foodstuffs, etc). Nevertheless, there is considerable social awareness and concern regarding the use of nanomaterials in foods, due to the scant information provided on their possible effects on human health. This is why the scientific community is focusing their research work on the effects and toxicity of these nanomaterials, publishing new works and creating databases. In consequence, AZTI-Tecnalia is currently working on the development of a rapid toxicological test based on the zebra fish animal model, in order to find out the effects, in the short and the long term, of nanomaterials and nanoparticles that have applications in foodstuffs.

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
