title: Controlling aqueous silica nanoparticle synthesis in the 10-100 nm range.
abstract: We describe the control of size and homogeneity in silica nanoparticle dispersions, prepared by a two-phase arginine catalysed aqueous method, through varying the upper organic solvent phase. The final particle dispersion characteristics can be controlled by varying features including solvent type and interfacial area, related to the rate of monomer transfer at the TEOS/water interface.
