Magnetic acidified silica nanoparticles

Magnetic silicon oxide nanoparticles have a core-shell structure, with a superparamagnetic iron oxide core inside and a silicon oxide shell covering the outside.

Magnetic silica microparticles are all submicron in size, and the hydrophilicity of the silica surface ensures good dispersion of the microparticles in water. They are typically used for the extraction and purification of nucleic acids. The surface of the unmodified products has silica hydroxyl groups, allowing for the extraction of DNA and RNA from blood, cell culture media, animal and plant tissues, and forensic samples. Carboxyl group-modified products are suitable for applications such as the purification of PCR products and the selection of NGS fragments. Magnetic silica products modified with other functional groups (such as thiol groups, epoxy groups, etc.) are also available for custom orders.
