![عکس صفحه اول مقاله: Multi-component hybrid inorganic–organic–inorganic particles with various metal oxide outer shells Multi-component hybrid inorganic–organic–inorganic particles with various metal oxide outer shells](/preview/png/1324656.png)
Non-agglomerated hybrid particles of 200 nm diameter with an outer metal oxide shell were prepared by reacting the COOH groups of poly((S)-N-dicarbazolyl-lysine)-covered silica particles with metal alkoxides, such as titanium, zirconium and aluminum alkoxides, followed by sol–gel processing. With tetraethoxysilane (Si(OEt)4), the silica particle core was growing rather than forming an external metal oxide shell, as observed for the other tested metal alkoxides.
