IC50 values of different hybrid Ag-TiO2 nanoparticles with and without UV light irradiations. TiO2 P25 (Degussa P25) and TiO2 R-902 (DuPont Ti-Pure R-902) were two commercial TiO2 nanoparticles. Two different molar ratios of AgNO3 and TiO2 including 1:10 and 1:50 were respectively employed to prepare Ag nanoparticles deposited onto the TiO2 nanoparticles by NaBH4 reduction and UV photoreduction to form the samples of Ag-P25 1:10 NaBH4, Ag-P25 1:50 NaBH4, Ag-P25 1:50 UV, Ag-R902 1:10 NaBH4, Ag-R902 1:50 NaBH4 and Ag-R902 1:50 UV. Ag nanoparticles and AgNO3 were purchased from QuantumSphere, Inc. Reproduced with permission from ref. [68]. Copyright © 2011, American Chemical Society.
