Nanomag-dyPEG are a novel and proprietary class of magnetic and fluorescent nanoparticles of small size, functionalized with an organic ligand and DyLight650® and embedded in block copolymer, carboxyl-terminated, homogeneously dispersed in buffer phosphate for use in industrial and as precursor for life science applications.
Nanomag-dyPEG are synthesized using the polyol synthesis method, then functionalized with organic ligand and DyLight650® and embedded in the polymeric matrix after nanoprecipitation in aqueous medium.
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-dyPEG 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-dyPEG have been used in a broad variety of life science applications (see References).
