Biomimetic Synthesis of Hybrid Silicananoparcles Mediated by Linear Polyamines

We report the biomimetic synthesis of hybrid silica nanoparticles mediated by linear cationic Poly (AM-co-DMC). The hybrid silica nanoparticles were simply synthesized by stirring a mixture of aqueous solution of Poly (AM-co-DMC) with TMOS at ambient temperature for typically 30 min. The hybrid nanoparticles were well characterized with FT IR, TEM, TEM-EDX and TGA. The representative hybrid nanoparticles are roughly spherical, with a number-average diameter of around 15 nm and good monodispersity. We also found that the formation of hybrid nanoparitlces depended on the reaction times for silica deposition. Our new hybrid particles are expected to be potentially applicable for catalysis and biomedical carriers.
