“…In particular, for Ib, the dispersion of nanoparticles (NPs) in monomers has been reported: TiO 2 /organosilicon [50,60], AlCeO 3 /HMDSO/ethanol [45], ZnO octane [57], polyhedral oligomeric silsesquioxane (POSS)/HMDSO [76]. In case II, a gaseous monomer is often inlet, as ethylene, with an aerosol in an aqueous solution of vancomycin [63,73,74], gentamicin [72] or lysozyme [59]; on the other hand, the monomer can be inlet by means of a bubbling system, as reported for the deposition of Ag NPs containing films [62], or silica layers entrapping TiO 2 NPs [61]. The additive can be a compound soluble in the aerosol liquid feed, but it can consist of both organic (e.g., polymer nanopowder) or inorganic (metals or metal oxides) nanoparticles.…”
