Abstract
The magnetic capture and manipulation of metallic nanoparticles can be interesting for many small-scale synthetic reactions, e.g., in the area of fine chemical production. Here, the separation of colloidal platinum nanoparticles from solution by means of magnetic beads is investigated. Therefore, magnetic beads functionalized with avidin are employed and a functionalization of the metal nanoparticles with biotin is performed. It is shown that the functionalized nanoparticles can be separated by the magnetic beads with common external magnetic field strengths. Furthermore, since a regain of the catalytic nanoparticles material is of inherent interest, several means of separation of the nanoparticles from the magnetic beads are investigated and compared.
