Open the CIPO recordAbstract From the Canadian patent
The invention relates to nanoparticles of noble metals having a controlled , microstructure which leads to the appearance of ferromagnetic behaviour in said nanoparticles, thereby enabling the use of very small magnets (< 5 nm) in a range in which standard ferromagnetic metals behave as superparamagnetic entities (disappearance of hysteresis cycle). The inventive nanoparticles can be used, for example, to reduce the dimensions in magnetic recordings as well , as in biomedicine as tools for biomolecule recognition nuclear magnetic , resonance imaging, drug-release control or hypothermia treatments.
