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.

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...

For the first time, scientists have succeeded in studying the strength of hydrogen bonds in a single molecule using an atomic force microscope. Researchers from the University of Basel’s Swiss Nanoscience Institute network have reported the results in the journal Science Advances.
Hydrogen is the most common element in the universe and is an integral part of almost all organic compounds. Molecules and sections of macromolecules are...
