Magnetic silica microspheres are strongly magnetically responsive, biocompatible magnetic beads that are stably dispersed in water and organic solvents to avoid swelling. The introduction of silicon dioxide shields the magnetic dipole interaction and improves its biocompatibility. The silica hydroxyl groups on the surface of the magnetic beads are able to specifically bind to nucleic acids in solution through hydrogen bonding and electrostatic interaction, allowing direct separation of nucleic acids from complex biological systems. At the same time, the surface Si-OH can make a variety of substances bound to the surface of the particle to achieve chemical modification. Different organic functional groups can be introduced, such as COOH, NH2, etc., to make its surface functionalized, and can also covalently bind A variety of biomolecules, such as Streptavidin, Biotin and Protein A, etc., to improve its biological targeting, and be applied in biological analysis, biochemical detection and other fields.

Magnetic polymer microspheres have a sandwich structure, with an inner core of porous polymer microspheres and an outer polymer coating of different materials to meet different application requirements, with the magnetic material filling the pores between the two. The diameter of the microspheres ranges from 1.5 to 20 μm, and the particle size is highly homogeneous with a CV of less than 3.0%. The microsphere surface is a double-layer hydrophilic coating with very low surface non-specific adsorption, which is particularly suitable for the development of high-sensitivity bioassay methods, and has a wide range of applications in various fields of immunoassay and immune separation, which can be used in magnetic particles chemiluminescence, immunoprecipitation and co-precipitation, magnetic separation of cells, and nucleic acid-specific capture, and so on.

Magnetic agarose microspheres were produced by dispersing magnetic iron oxide nanoparticles around 10 nm in agarose microspheres with an agarose content of 6.0%. The agarose microspheres were all cross-linked internally, with a wide distribution of particle sizes between 40 -120 μm. The magnetic agarose microspheres are coupled with Protein A or Ni-NTA affinity ligands on the surface, which can be used in small-scale antibody/protein purification, immunoprecipitation, pull-down experiments and other scenarios. Magnetic agarose microspheres with other functional groups or unmodified are available as customized products.

With its localized surface plasmon resonance phenomenon, gold nanoparticles have excellent optical properties, on the one hand, enhance the electromagnetic field around the gold nanoparticles to produce a strong bright spot, which can be applied to imaging, on the other hand, the incident energy is converted into heat to increase the local temperature around the near gold nanoparticles, which can be applied to photothermal therapy to assist the launch of the treatment, especially in the treatment of deep-seated tumors. At the same time, gold nanoparticles have better biocompatibility, lower biotoxicity and surface adsorption carrier ability, which can modify target molecules, drug molecules and imaging contrast agents and other functional molecules, and functionalized gold nanoparticles have applications in cell induction, drug carriers, therapeutic methods, clinical diagnosis, and antibody labeling.
