Natural TiO₂-Nanoparticles in Soils: A Review on Current and Potential Extraction Methods

A comparative proteomics study of Arabidopsis thaliana responding to the coexistence of BPA and TiO2-NPs at environmentally relevant concentrations

“…Thus, in this study we used environmentally relevant levels of BPA ranging from 10 to 1000 μg·kg −1 and TiO 2 -NPs concentrations from 1 to 100 mg·kg −1 for the treatments as shown in Table 1 . Uncertain parameters in biosolids have been reported, such as organic matter ( Simonin et al, 2021 ; Wu et al, 2017 ; Zhu et al, 2012 ) and soil colloid ( Campos et al, 2020 ; Philippe et al, 2018 ; Sun and Zhou, 2015 ). In order to avoid the discrepancy, agar media were used for the treatment and control groups and supplemented with growth medium ( Weigel and Glazebrook, 2002 ) (400 mL 1 × MS medium with 0.6% (g/g) agar powder).…”

First Evidence of Anthropogenic Tio2 Nanoparticles Occurrence in Chilean Rivers

“…These structures are associated with the organic matter of the samples, which is expected since TiO 2 nanoparticles of natural origin tend to be hydrophobic and have a greater affinity for this matter, unlike manufactured TiO 2 nanoparticles that have a wide coating variability. which can be hydrophilic or hydrophobic (Campos et al, 2022).…”

“…The affinity of these nanoparticles with organic matter is contingent upon the type of surfactant they are associated with. Consequently, one can anticipate the presence of nanoparticulate structures associated with various forms of organic matter, including lipids or in their free form (Campos et al, 2022;Liao & Liao, 2007). TiO 2 nanoparticle production accounts for around 37 % of total nanoparticle production, and it is one of the most used nanomaterials worldwide (Yadav & Ahmaruzzaman, 2022); this statistic implies a high probability that TiO 2 will be found as waste in natural water bodies due to increases in the use of these products (Keller et al, 2010).…”

Synthesis Methods and Applications of TiO2 based Nanomaterials

“…Therefore, PDT and SDT cause little or no toxicity and cytotoxicity. Therefore, these methods are strong alternatives to chemotherapy and classical radiotherapy [51]. The schematic view of PDT and SDT is shown in Figure 11.…”
