Creative Diagnostics offers a comprehensive list of basic, coated, functional and
conjugated silica particles with uniform size and shapes. Our silica particles in the size
range of 10 nm to 1.5 µm are monodisperse and nonporous particles with a density
of 2.0 g/cm³, while particles between 3 and 20 µm are porous particles with a
density of 1.8 g/cm³.
Basic silica particles have a hydrophilic surface with terminal Si-OH bonds, which are
highly stable in organic solvents and aqueous buffers. By precisely surface
engineering, silica particles are either functionalized with active groups such as
carboxyl, amine and NHS, or conjugated with a variety of biological ligands and
