Application

Monodisperse nonporous silica nanoparticles find application in drug delivery and molecular imaging[1][2] whereas micron sized particles are used in liquid chromatography.[3] 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 (500 nm) is a versatile filler material that can be used in a variety of applications such as catalysts, coatings, and absorbents.[4] It can also be used in the development of nanomedicine for biomedical and clinical applications.[5][6]
