Iron oxide nanocrystals have become a versatile tool in biomedicine by presenting low cytotoxicity while offering a wide range of tuneable magnetic properties that may be implemented in magnetic separation, drug and heat delivery or bioimaging. These capabilities rely on the unique magnetic features obtained when combining different iron oxide phases, so that an important portfolio of magnetic properties can be attained by the rational design of multicomponent nanocrystals. In this context, Raman spectroscopy constitutes an invaluable and fast-performance tool to gain insight into the different phases forming part of the nanocrystals to be used, allowing to correlate the magnetic properties with the envisaged bio-related applications.
