The invention relates to a method for AFM in which it is possible to measure magnetic information from single, isolated magnetic markers in on the scale of nm.The method is used to differentiate between marked and unmarked arrears, for measuring the magnetic AC-susceptibility of the marker and to determinate the geometry of a marker. Hereby the measured signal is further processed by an amplifier. The method utilises nanoparticles (marker), which are placed on or in a sample. Because of the alternating magnetic field these particles are stimulated to create a magnetic flow, which is dependent on the AC-susceptibility of the particle and on with the external alternat-ing field. With this effect, the entire magnetic flow in the area around the marker is changed. Furthermore, the entire sample is scanned in 2-D or 3-D and differences in the magnetic flow, which generate a magnetic interference, are measured by detecting the oscillation of the AFM tip. This oscillation is the measurement signal, which makes it possible to measure smaller magnetic interac-tions.

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.

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...
