Schematic illustration of the preparation of monodisperse hybrid particles (organic microparticles coated with inorganic silica nanoparticles). (A) Photocurable droplets containing the monomers (TPM and DDMA) and the photoinitiator in the continuous phase (PVA solution) are formed by a shear force driven pinch-off mechanism. Under UV-irradiation, photopolymerization is initiated. (B) Hydrolysis of ehtoxide group for the growth reaction of silica particles onto the polymeric microparticles. (C) Final stage of complete synthesis of polymeric core microparticle coated with silica nanoparticles as a shell (organic-inorganic hybrid particle).
