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 (2 μm) is a micro-sized filler material can be used as a spacer in liquid crystals, high performance liquid chromatography (HPLC), and nanomedicine for biological applications.
