Toxicological impact of TiO nanoparticles on .

The concern regarding the toxicological effects of nanoparticles (NPs) on the terrestrial environment is increasing. To avoid risks of exposure to these NPs in the environment, it is essential to develop an understanding of their reactivity, toxicity, and persistency. Due to the increased usage of nano-titanium dioxide (TiO) in various industrial products, an exponential increase in exposure is expected, which would exacerbate concerns about its ecological risks.

Inhibitory effect of TiO NPs on symbiotic arbuscular mycorrhizal fungi in plant roots.

While nanoparticles (NPs) are known to exhibit antimicrobial properties, their effects on symbiotic arbuscular mycorrhizal fungi (AMF) in plant roots has to be carefully examined as NPs particularly of titanium dioxide (TiO) reach plant roots through varied sources such as fertilisers, plant protection products and other nanoproducts. The objective of the present study is to assess the effect of TiO NPs on the symbiotic behaviour of AMF colonising rice ( L.) plants.

Microbicidal activity of TiO2 nanoparticles synthesised by sol-gel method.

In this study, the authors investigated antimicrobial activity of TiO2 nanoparticles (NPs) synthesised by sol-gel method. As synthesised TiO2 NPs were characterised by X-ray diffraction, scanning electron microscopy and ultraviolet-visible absorption spectroscopy. The antimicrobial activity of calcined TiO2 nanoparticle samples was examined in day light on Gram positive bacteria (Staphylococcus aureus, Streptococcus pneumonia and Bacillus subtilis), Gram negative bacteria (Proteus vulgaris, Pseudomonas aeruginosa and Escherichia coli) and fungal test pathogen Candida albicans.
