PhD project

“Subsurface Imaging” of magnetic nanoparticles and quantification of nanomechanical properties of polymers and biological materials by bimodal atomic force microscopy.

MFM not only allows for the detection of the magnetical properties of nanoparticles but also for the detection of their position in case they are situated within a specimen. The bimodal excitation of the cantilever makes it possible to detect the position of the nanoparticle and the mechanical properties of the overlying layer at the same time. Such measurements can be performed in varying environments, e.g. liquids. At the same time, it is possible to achieve high imaging rates. Thus, we have a tool that offers the possibility to observe the diffusion processes of functionalised nanoparticles into human cells. In pharmacotherapy these processes are not fully explored yet. Main goal of this project is to establish the connection between the favoured sites of permeation of the nanoparticles and the mechanical properties of the endothelial cells.
