We offer solutions in the field of iron oxide nanoparticles. We specialize in the production of functionalized black iron oxide (II, III), also known as magnetite, according to customer requirements. Our production is based on the innovative technology of producing hybrid nanoparticles of this compound, using substances that are completely safe for the environment. Thanks to this method, we are able to offer magnetite nanoparticles on an industrial scale while maintaining their unique superparamagnetic properties.
