Silica particles, Paramagnetic (SiO2-MAG)
Our monodisperse magnetic silica particles are prepared by a new strategy recently developed by microParticles GmbH. The new process involves the following steps:
i) preparation of monodisperse nanoporous silica particles using a modified sol-gel process
ii) in situ coprecipitation of iron oxide nanoparticles within the porous silica network
iii) microencapsulation/functionalization.
Through this strategy, magnetic silica particles with high monodispersity (CV < 5 %), excellent magnetic response, and high colloidal stability can be achieved. All magnetic silica particles are available in a range of discrete sizes from 500 nm to 8 µm and can be delivered as a 5 % w/v aqueous suspension. They can be used in a variety of applications like cell separation, nucleic acid isolation, biomolecule purification, and particle-based immunoassays.
