The tracer quality can be improved by optimizing the shape, core size and shell of the nanoparticles. However, such a defined synthesis is quite challenging. Biogenic magnetic nanoparticles, so-called magnetosomes, synthesized by magnetotoactic bacteria, might provide a promising alternative. In this study, magnetosomes isolated from different Magnetospirillum gryphiswaldense mutant strains biomineralizing particles with varying core diameters were investigated with regard to their usability as tracers for MPI.en2365-903320231, suppl. 1Infinite Science Publishinghttps://creativecommons.org/licenses/by/4.0/PhysikTechnikIngenieurwissenschaftenJournal Article10.15480/882.507210.18416/IJMPI.2023.230306610.15480/882.5072Other
