Streptavidin magnetic beads (SA beads for short) refer to magnetic microspheres with specific bioactive substances (streptavidin) modified on their surface.Streptavidin magnetic beads are a type of biological nanomagnetic beads with a surface functional group of streptavidin. They can specifically bind to biotin or biotin labeled molecules, thereby separating biotinylated molecules. The strong binding and multi-level amplification effect […]

Chemiluminescent magnetic beads are a type of sandwich structure magnetic beads that contain a porous polymer core, which is coated with special polymer materials to obtain specific surface properties. Magnetic materials are filled in the gaps between the two, which can enable the microspheres to achieve greater buoyancy and uniform particle size; At the same

Specially designed for nucleic acid extraction and purification, with surface modification of a large number of silanol groups (silanol groups), it can undergo specific binding with nucleic acids in solution under high salt and low pH conditions through hydrophobic, hydrogen bonding, and electrostatic interactions, without binding with other impurities (such as proteins), quickly separating nucleic

Fluorescent microspheres are obtained by post dyeing latex microspheres, with fluorescent dyes embedded inside the microspheres. The fluorescence signal is stable and will not leak. Therefore, there is no need to worry about changes in fluorescence intensity caused by dye leakage, nor about the impact of dyes on the crosslinking of microspheres and proteins. SHBC

SHBC colored microspheres are obtained by dyeing latex white microspheres, filled with nearly 20% oil soluble dyes in the matrix inside the microspheres. The color is bright and stable, which can present different color bands for different detection items of the same test strip and solve the problem of mutual interference when multiple items are

SHBC latex microspheres (50nm-400nm) can be applied in particle enhanced immunoturbidimetry, an improved immunoturbidimetric analysis method based on polyclonal antibodies. Genetic engineering methods are used to combine antibodies with latex particles, and when antigen antibodies combine, an antigen antibody latex microparticle complex is formed, enhancing reaction absorbance. Solid phase immunoassay, latex agglutination test, and microsphere

Photonic crystals (Photonic Crystal) was founded in 1987 by S. John and E. YablonovitchProposed independently, it is an artificial microstructure formed by the periodic arrangement of media with different refractive indices. Photonic crystals are photonic bandgap materials, and from the perspective of material structure, photonic crystals are a class of artificially designed and manufactured crystals with periodic dielectric structures at the
