Application

Monodisperse nonporous silica nanoparticles find application in drug delivery and molecular imaging whereas micron sized particles are used in liquid chromatography. We offer highly monodisperse (coefficient of variance <10%) nonporous silica in size varying from 150 nm to 50 μm. The high monodispersity of our particles makes them suitable for aforementioned applications.
Silica monodispersed, non-porous (200 nm) is a versatile filler material that can be used in a variety of applications such as catalysts, coatings, and absorbents. It can also be used in the development of nanomedicine for biomedical and clinical applications.
