Halle 12 / E53 MEDICA SPORTS HUB Learn, train and network at the act ion area of the MEDICA SPORTS HUB. Live and active. At the large action area of the MEDICA SPORTS HUB in Hall 4 visitors can test innovative sports and health equipment in practice, learn from experts or train like professional athletes. Selected experts from the fields of health and fitness monitoring, training, regeneration and the Pro Sports Corner will present themselves at the four MEDICA SPORTS HUB AREAS 2023. The networking platform focuses on sports for health, fitness and professional sports and links relevant players and programs in the halls. The MEDICA SPORTS HUB connects the activities of the established MEDICA MEDICINE + SPORTS CONFERENCE with the exhibition halls. Hall 4 / K56 Quantum sensors A mini-magnetic resonance tomograph made of diamond The development of tumors begins with miniscule changes within the body’s cells; ion diffusion at the smallest scales is decisive in the performance of batteries. Until now the resolution of conventional imaging methods has not been high enough to represent these processes in detail. A research team lead by the Technical University of Munich (TUM) and including Fraunhofer IAF has developed diamond quantum sensors which can be used as highresolution magnetic resonance tomographs. Nuclear magnet ic resonance (NMR) is an impor tant imaging method in research which can be used to visualize tissue and structures without damaging them. The process is better known from the medical field as Magnetic Resonance Imaging (MRI), where the patient is moved through a large tube on a table. The MRI device creates a very strong magnetic field which interacts with the tiny, weak magnetic fields of the hydrogen nuclei in the body. Since the hydrogen atoms are distributed characteristically in different types of tissue, it becomes possible to differentiate organs, joints, muscles and blood vessels. NMR methods can also be used to visualize the diffusion of water and other elements. Research for example often involves observing the behavior of carbon or lithium in order to explore the structures of enzymes or processes in batteries. “Existing NMR methods provide good results, for example when it comes to recognizing abnormal processes in cell colonies,” says Dominik Bucher, Professor of Quantum Sensing at TUM. “But we need new approaches if we want to explain what happens in the microstructures within the cells.” Sensors made of diamond The research team produced a quantum sensor made of synthetic diamond for this purpose. “We enrich the diamond layer, which we provide for the new NMR method, with special nitrogen and carbon atoms already during growth,” explains Dr. Peter Knittel of the Fraunhofer Institute for Applied Solid State Physics IAF. After growth, electron irradiation detaches individual carbon atoms from the diamond’s perfect crystal lattice. The resulting defects arrange themselves next to the nitrogen atoms — a so-called nitrogen-vacancy center has been created. This has quantum mechanical properties. “Our processing of the material optimizes the duration of the quantum states, which allows the sensors to measure for longer,” adds Knittel. Quantum sensors pass the first test The quantum state of the nitrogen-vacancy centers interacts with magnetic fields. “The MRI signal from the sample is then converted into an optical signal which we can detect with a high degree of spatial resolution,” Bucher explains. In order to test the method, the TUM scientists placed a microchip with microscopic water-filled channels on the diamond quantum sensor. “This let us simulate the microstructures of a cell,” says Bucher. The researchers were able to successfully analyze the diffusion of water molecules within the microstructure. In the next step the researchers want to develop the method further to enable the investigation of microstructures in single live cells, tissue sections or the ion mobility of thin-film materials for battery applications. “The ability of NMR and MRI to directly detect the mobility of atoms and molecules makes them absolutely unique compared to other imaging methods,” says Prof. Maxim Zaitsev of the University of Freiburg. “Nowwe have found a way to also significantly improve their resolution.” A research team led by the Technical University of Munich has developed a novel NMR method that can detect microstructures using diamond-based quantum sensors Foto: Technical University of Munich | Andreas Heddergott acad group GmbH www.acad-group.de Halle: 8a • Stand: N35 iFactory3D GmbH www.ifactory3d.com Halle: 12 • Stand: E53-36 JenLab GmbH www.jenlab.de Halle: 15 • Stand: K22 VmedD GmbH www.vmedd.de Halle: 12 • Stand: D65 Nichtaussteller: TÜV SÜD AG www.tuvsud.com Messetelegramm Anzeige Der Gesundheitssektor gehört zu den größten Verbrauchern von Ressourcen und verursacht ein hohes Müllaufkommen. Maßnahmen diesbezüglich können demnach besonders wirksam sein, wenn es um die Bekämpfung des Klimawandels und seiner Folgen geht. Mit der ForumSession „Sustainability in Healtcare - Creating green healthcare initiatives for a positive impact on the environment“ und einem Beitrag von Prof. Edda Weimann startet der Mittwoch (15.11., um 11 Uhr) beim MEDICA CONNECTED HEALTHCARE FORUM in Halle 12. Prof. Weimann ist Direktorin des Geneva Sustainability Centre. Sie verfügt über langjährige Erfahrung hinsichtlich der Thematik, wie Klimaneutralität von Kliniken erreicht werden kann. Die Vision des Start-ups Resourcify mutet geradezu revolutionär an. Das Entwicklerteam will eine abfallfreie Zukunft ermöglichen, getragen von Technologiefortschritten. Wie sie sich das vorstellen, das wird Meike Lessau, Head of Circularity bei Resourcify, konkretisieren. Wege zu mehr Nachhaltigkeit
