  Magnetic nanoparticles have many applications in biomedicine and other
technical areas. Despite their huge economic impact, there are no standardised
procedures available to measure their basic magnetic properties. The
International Organization for Standardization is working on a series of
documents on the definition of characteristics of magnetic nanomaterials. We
review previous and ongoing European research projects on characteristics of
magnetic nanoparticles and present results of an online survey among European
researchers.
