Mobile diagnostics by smartphone and image analysis for detecting antibiotic resistance
Fraunhofer FIT demonstrates a mobile wireless system that monitors the health of elderly people in their own homes, using miniature sensors, and also a novel optical system for detecting antibiotic resistance, which can determine in just two hours if bacteria react to a specific antibiotic.
At BIOTECHNICA 2013, Fraunhofer FIT demonstrates the first system that integrates three different sensors in one platform. A nano potentiostat measures biochemical information in a patient's assay, e.g. glucose, lactate or cholesterol levels. A fluorescence sensor is used to detect color-marked biomarkers.

A SpO2 sensor monitors heart rate and arterial oxygen saturation. A smartphone app processes the data from the three sensors and transfers them to a server. For secure data communication, a Bluetooth connection with a specifically developed protocol is used.
"Our aim was to integrate, in one mobile device, several miniature sensors that measure relevant diagnostic parameters and communicate their data wirelessly", says Professor Harald Mathis, head of the department 'Biomolecular Optical Systems' of the Fraunhofer Institute for Applied Information Technology FIT.
As devices that measure biometrical data do not use standardized protocols, we developed a sensor platform that takes the data from the different sensors, processes them and sends them to a smartphone. The smartphone can then transmit the data to the patient's physician.
The system was developed by Fraunhofer FIT in cooperation with Charité and T-Systems Deutschland in the BMBF/EU-funded project Nanoelectronics for Mobile AAL Systems – MAS.
Fraunhofer FIT's second exhibit is an image analysis system for bacteria diagnostics. Antibiotic resistance is a growing threat to our health. Many antibiotics are losing their effectiveness. Unfortunately, there are no universal flash tests for antibiotic resistance. FIT's new system uses an optical process that can determine in just about two hours if bacteria react to a specific antibiotic.

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.
