Description of project
|Magnetic force microscopy does not only enable the detection of magnetic nanoparticles but also the detection of their position beneath the sample surface that can be combined with the recording of the mechanical properties of the overlying substance. This is made possible by by the bimodal excitation of the cantilever. Such measurements can be performed in various environments, e.g., liquids, with a high imaging rate. This tool facilitates the detection of, for example, diffusion processes of functionalised nanoparticles in human cells. In targeted drug delivery. the movement of active substance carriers is not entirely understood. Objective of this project is the establishment of a correlation between the favoured intruding sites of the nanoparticles with the mechanical properties of endothelial cells.|
