A multifunctional nanocomposite based on ZnO and mesoporous SiO 2 is presented for potential biomedical applications. A simple modified hydrothermal method is used to synthesize PEG‐coated ZnO whereas mesoporous SiO 2 was obtained through sol–gel method. Nanocomposite is obtained by stirring the two products in deionized water under slightly acidic conditions. Biocompatibility is introduced through surface coating of ZnO with polyethylene glycol and of SiO 2 with chitosan. ZnO nanoparticles with particle size of 50–80 nm and mesoporous SiO 2 with particle size of 600 nm are obtained in the final composite. The nanocomposite has island‐type coat of ZnO nanoparticles on submicron mesoporous SiO 2 with photoluminescent properties and drug‐carrying ability.
