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.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
