Abstract
This contribution describes a fast and facile method for fabrication of robust magnetic stir-bars composed of molecularly imprinted polymers (MIPs) combined with magnetite particles. This was achieved through a prior optimization of the protocol presented here, in particular, the selection of cross-linker and porogen suited for obtaining a durable monolithic magnetic stir-bar. In-house prepared magnetite nanoparticles (Fe3O4) are used as magnetic core, coating them with molecularly imprinted polymers through a simple process of bulk polymerization. Procedures for magnetite synthesis, preparation of polymerization mixture, stir-bar synthesis, and analytical application are described.
