Silica Microspheres, Carboxyl, 0.5μm

Silica Microspheres, carboxyl-functionalized, 100% solids, 0.5µm

These silica microspheres are available with a nominal diameter of 0.5µm to allow the researcher to tailor his/her product design for specific assays.

Our non-functionalized silica microspheres are also available in a wide range of sizes. Polysciences' uniform, non-porous silica microspheres are available in diameters of ~150nm to 5µm. The particles typically have size CVs of 10-15%. For applications that require highly stringent CVs (e.g. 2-5%), call for product availability. They are suitable platforms for surface modification with functionalized organosilanes to introduce specific binding sites.

Custom synthesis is available on request for specialty products.
