Effect of TiO2 nanoparticles on the acute toxicity of Ag nanoparticles in zebra fish (Danio rerio)
The potential entry of nanomaterials into the water ecosystems increased following their increasing use. In addition to the direct effects of nanomaterials on aquatic organisms, they also affect the toxicity of other pollutants on aquatic organisms. This study assessed the presence of titanium dioxide nanoparticles (nTiO2) in water on acute toxicity of silver nanoparticles (AgNPs) on zebra fish...
متن کاملSynthesis and characterization of Ag nanoparticles and Ag loaded TiO2 photocatalysts
Ag nanoparticles and Ag-TiO2 nanostructures were grown on (001) SiO2 quartz substrates by pulsed laser deposition using a KrF* excimer laser source (λ= 248 nm, τFWHM~10 ns, ν= 10 Hz) for the irradiation of Ag and TiO2 targets. The obtained structures were characterized by atomic force microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, and UV-visible absorption spectroscopy. Photoc...
متن کاملNon-UV germicidal activity of fresh TiO2 and Ag/TiO2.
Fresh TiO2 was found to possess a strong germicidal activity even without UV irradiation. Live Yeast (Saccharomyces cerevisiae) cells in contact with fresh TiO2 were found deformed and dead after 15 min contact. The cause of germicidal activity was discussed from the observed cell deformation, lysis and increased absorption at 1680 cm(-1) in FT-IR spectra of the affected cells, which proved the...
متن کاملStructure and Formation Model of Ag/TiO2 and Au/TiO2 Nanoparticles Synthesized through Ultrasonic Spray Pyrolysis
This article explains the mechanism of the metal/oxide core-shell Ag/TiO2 and Au/TiO2 nanoparticle formation via one-step ultrasonic spray pyrolysis (USP) by establishing a new model. The general knowledge on the standard “droplet-to-particle” (DTP) mechanism, nucleation, and growth processes of noble metals, as well as physical and chemical properties of core and shell materials and experiment...
