Flexible magnetics filaments:properties and applications - FMF

Project summary

Different technologies for synthesis of flexible magnetic filaments are developed. These include linking magnetic micro-particles by DNA, attaching magnetic nanoparticles to polyelectrolyte bundles, extraction of magnetosomes from magnetotactic bacteria and other. Flexible magnetic filaments are interesting for applications as self-propelling microdevices (for targeted transport), micro-mixers (for microfluidics), different sensors (micro rheology). Numerical algorithms for predicting their behavior in magnetic fields of different configurations will be developed, including algorithms based on curve dynamics, lattice Boltzmann method, Brownian dynamics. Obtained numerical results will be compared with experimental results of measurement of flows fields around magnetic filaments, their buckling instabilities. As a result new technology will be developed for DLS measurements giving access to characteristics of translation and rotational motion of string like magnetic micro-objects.
