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 (750 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]

    Molecular plant pathology, 14(6), 623-634 (2013-04-30)
    Salicylic acid (SA) acts as a signalling molecule in plant defence against biotrophic and hemibiotrophic phytopathogens. The biosynthesis of SA on pathogen detection is essential for local and systemic acquired resistance, as well as the accumulation of pathogenesis-related (PR) proteins.
