TiO nanoparticle (NPs) biosynthesis is a low cost, ecofriendly approach developed using the fungi TFR 7. To determine whether TiO NPs is suitable for nutrient, we conducted a two part study; biosynthesis of TiO NP and evaluates their influence on mung bean. The characterized TiO NPs were foliar sprayed at 10 mgL concentration on the leaves of 14 days old mung bean plants. A significant improvement was observed in shoot length (17.02%), root length (49.6%), root area (43%), root nodule (67.5%), chlorophyll content (46.4%) and total soluble leaf protein (94%) as a result of TiO NPs application. In the rhizosphere microbial population increased by 21.4-48.1% and activity of acid phosphatase (67.3%), alkaline phosphatase (72%), phytase (64%) and dehydrogenase (108.7%) enzyme was observed over control in six weeks old plants owing to application of TiO NPs. A possible mechanism has also been hypothesized for TiO NPs biosynthesis.

ZnO and TiO nanoparticles (NPs) are widely employed for their antibacterial properties, but their potential environmental impact is raising concerns. This study aimed to assess their single and combined effects at environmentally relevant concentrations (210 μg L) on rainbow trout (Oncorhynchus mykiss) gills microbiota and immune functions. 16S rRNA gene sequencing performed after 5 and 28 days of exposure suggests that TiO NPs had a more immediate impact on bacterial diversity, while prolonged exposure to the mixture altered community composition.

Antimicrobial polymeric coatings rely not only on their surface functionalities but also on nanoparticles (NPs). Antimicrobial coatings gain their properties from the addition of NPs into a polymeric matrix. NPs that have been used include metal-based NPs, metal oxide NPs, carbon-based nanomaterials, and organic NPs.

This study investigated the effects of various titanium nanoparticles (TiONPs) on the structure, function, and trophic levels of the wheat rhizobiome. In contrast to the typically toxic effects of small nanoparticles (~10 nm), this research focused on molecular TiO and larger nanoparticles, as follows: medium-sized (68 nm, NPs1) and large (>100 nm, NPs2). The results demonstrated significant yet diverse impacts of different TiO forms on the rhizosphere microbiota.

Titanium dioxide (TiO) nanoparticles (NPs) are incorporated into numerous consumer products yet data as to potential adverse health effects remains inconclusive. In this paper we physically characterize 16 nanoforms of TiO from different manufacturers of different size, crystalline structure and with surface chemistry. Physical measurements of the particles were performed and compared with those provided by manufacturers revealing several discrepancies.
