R. Müller, Th. Heinze: Structuring of Magnetic Particle doped Biopolymer through Mag-netic Induced Matrix - Particle Interaction
Description
Aim of the project is remote control of the properties of biocompatible hybrid materials consisting of melt-able biopolymers (especially dextran esters) and magnetic nanoparticles by means of interaction be-tween matrix and particles using magnetic fields. It will be investigated how a local enrichment of particles and a structural i.e. magnetic anisotropy, respectively, can be generated.
By such an anisotropy or particle enrichment near the surface. Surface properties can be influenced in de-pendence on the structure of the dextran ester. That leads to macroscopical properties relevant for appli-cations, like the specific absorption rate (heating be-havior in an AC-magnetic field), roughness, wettability etc. Moreover it will be investigated if a reorientation of matrix material (phase separation, crystallization) takes place or can be induced. The composite sam-ples will be characterized by optical and Raman spec-troscopy, electron microscopy, magnetic methods and measurement of the surface energy. In case of a successful implementation of the concept a treatment of biofilms or cells is possible.
