Nanomag DEG
TEM of Nanomag DEG
Nanomag-DEG are a novel and proprietary class of magnetic nanoparticles of small size, not functionalized and homogeneously dispersed in diethylene glycol for use in industrial and life sciences applications.
Nanomag-DEG are synthesized using the polyol synthesis method.
At room temperature the assembly of particles behaves like a superparamagnet while near-to-zero properties reveal that the nanoparticles are blocked with remnant magnetization (Mr) and coercive field (Hc) different to zero.
Nanomag-DEG have demonstrated to respond to alternating magnetic fields exposure (radio wave range) converting the absorbed energy into heat with remarkable efficiency (SAR – Specific Absorption Rate)
Nanomag-DEG have been used as magnetic core in a broad variety of life science applications (see References).
