• Monodisperse Silica

    Monodisperse silica microspheres are ceramic spherical beads with tight particle size distributions and CV<10%.Ruixibio provides a rich selection of various silica nanoparticles and microbeads,size of our silica beads ranges from 200 nm to 80 um.

  • Amino functional Silica

    Ruixibio provides amine functionalized silica nanopartices or silica microbeads,size of our silica beads ranges from 200 nm to 40um,amine groups on these silica beads can be used to react with carboxylic groups, NHS esters and many others

  • Carboxyl functional Silica

    Ruixibio provides carboxyl functionalized silica nanopartices or silica microbeads,size of our silica beads ranges from 100 nm to 60um,carboxyl groups on these silica beads can be used to react with amine groups,and many others.

  • Mesoporous Silica

    Monodisperse mesoporous silica nanoparticles (MSNs) have the advantages of uniform size distribution, good water dispersion, high specific surface area, narrow pore size distribution and large pore volume, and have good biocompatibility. It can be used as an excellent carrier for fluorescent molecules, chemotherapeutic drugs, DNA/siRNA, proteins and other kinds of guest molecules for diagnostic, therapeutic and other biomedical applications.

  • Biological coating Silica

    Ruixibio provides Streptavidin,avidin and BSA coated Fe3O4 magnetic Nanoparticles,the particle size ranges from 30 to 150 nm.

  • Custom synthetic Silica

    We will keep on develop new Silica Bead products of high-tech.
