Inorganic supports such as silica microspheres have become increasingly important for a variety of applications. They offer the combined benefits of working with a bead platform and the unique properties of a silica substrate, including: flexibility, large specific surface area, improved binding kinetics over planar surfaces, robust statistics, flexible silanization chemistries, unique refractive index and density, low autofluorescence, low nonspecific binding of many biomolecules, hydrophilicity, and easy manipulation. SiO2 with carboxyl (COOH) surface groups for the covalent attachment of biomolecules. Carboxyl silica microspheres are sold in 1.0g amounts. Supplied dry, they are available in these nominal mean diameters: ~0.5μm, ~1.0μm, ~2.0μm, and ~5.0μm.:
