The vitaminB2@TiO2NPs were obtained at room temperature, by a method developed after trying several ratios of reactants. Briefly, 0.02 g of P25TiO2NPs were dispersed in 1 mL of ultra-pure water and stirred in a Vortex. Next, 200 μl of vitamin B2 dissolved in ultra-pure water (5.3 × 10−3 M) were added to 200 μL of P25TiO2NPs and the mixture was ultrasonicated for 1 hour to achieve a deep-yellow homogeneous suspension. The pellet obtained after centrifuging the suspension for 10 min at 4500 rpm was resuspended in ultrapure water, centrifuged again, and then lyophilized.

 The sulfide in the metathesis reaction step is ruthenium sulfide, sodium sulfide, ammonium sulfide or hydrogen sulfide. The second reaction, the reaction temperature is 10 to 40 ° C. The reaction temperature is 10 to 40 ° C. The reaction temperature is 10 to 40 ° C. The reaction temperature is 10 to 40 ° C. 5〜lh。 The stirring speed is 0~15m / s, the compounding time 0. 5~lh. The addition of a nonionic surfactant can be nucleated by the fine crystal of nZnS-BaS04, which can effectively inhibit the growth of crystal nuclei.

Australian researchers examined how titanium dioxide as a food additive affected gut microbiota in mice by orally administering it in drinking water. The study, published in the journal Frontiers in Nutrition in 2019, found the treatment could “alter the release of bacterial metabolites in vivo and affect the spatial distribution of commensal bacteria in vitro by promoting biofilm formation. We also found reduced expression of the colonic mucin 2 gene, a key component of the intestinal mucus layer, and increased expression of the beta defensin gene, indicating that titanium dioxide significantly impacts gut homeostasis.” The changes were then linked to colonic inflammation, along with a higher expression of inflammatory cytokines, which are signal proteins that help with regulation. The researchers concluded that titanium dioxide “impairs gut homeostasis which may in turn prime the host for disease development.”
