Nanostructured sensors for the United States’ company NanoSonic

14.01.2004


A research team from the Department of Electric and Electronic Engineering at the Public University of Navarre has designed nanostructured optical sensors and instrumentation to monitor these sensors, for the United States’ company NanoSonic, which has begun to market the product.

The optic fibre sensors are human hair-sized devices. The Public University of Navarre has developed a humidity sensor and a light source for applications with optic fibre sensors. Moreover, the Navarre team has designed and manufactured optic-electronic converters that incorporate a signal terminal for the sensor and which, in turn, can be connected to other electronic apparatus, such as a computer, and through which information gathered by the sensors can be consulted.

The collaboration between the Navarre university researchers and the North American company will continue as a result of the new contract for the design and development of electronic instrumentation for nanosensors, signed by both parties, and which will terminate in June of this year.



Dosage of medicines

Nanostructured materials are materials that are synthesised and ordered in their manufacture at a molecular level, and that are deposited with the precision of a few nanometers.

This technique involves the successive deposition of anionic and cationic materials, i.e., materials negatively and positively charged respectively and which can be organised in such a way that the coatings have a thickness in the order of nanometers. The technique is very versatile when combining materials and can provide a highly useful tool to synthesise materials sensitive to different biomedical variables.

A number of research projects on nanostructured materials are currently under way. One of the applications, for example, consists of the dosage of medicines in those cases where the medication is not to be absorbed immediately, but when a certain level is reached in the intestine. For this to happen, the capsule has to be permeable to the medicine only when that level inside the intestine has been reached, given that this is where its efficacy is at its optimum.

To this end, microcapsules have been created composed of a microscopic sphere inside which is the medicine to be dosed. This sphere covering the medicine, and depending on the conditions, opens and closes via a system of micro-pores. In this way the material can be programmed so that, when a certain level of intestinal acidity is reached, the pores open and release the medicine.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
