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 nonporous silica in aqueous solution, with sizes varying from 150 nm to 900 nm. The high monodispersity of our particles makes them suitable for aforementioned applications.
