3D-Imaging of Magnetically Labeled Cells
In project B7, magnetoelectric sensors will be utilized to map distributions of magnetically marked living cells in 3D biomaterial scaffolds. Small size, great sensitivity anisotropy and sharp mechanical resonance enable the MEMS sensors to detect higher harmonics of the magnetically excited superparamagnetic markers. Spatial resolution shall be achieved by mapping the sample or by sensor arrays and by solving the inverse problem. Magnetic cell loading strategies and scaffolds for controlling cell distributions will be developed. Experiments on macroscopic demonstrators and on living cells in scaffold materials will be carried out.
