Magnetic nanoparticles biosynthesized by bacteria might soon play an important role in biomedicine and biotechnology. Researchers of the University of Bayreuth have now developed and optimized a process for the isolation and purification of these particles from bacterial cells. In initial tests, magnetosomes showed good biocompatibility when incubated with human cell lines. The results, presented in the journal Acta Biomaterialia, are therefore a promising step toward the biomedical use of magnetosomes in diagnostic imaging techniques or as carrier in magnetic drug delivery applications.
