Background: In recent years, titanium dioxide (TiO) nanoparticles (NPs) have been widely used in various industries due to their favorable chemical properties, and their contamination of the environment has attracted much attention, especially to aquatic animals.
Methods: Therefore, we assessed the impact of TiO NPs (5 mg/L) on the marine bivalve, pearl oyster (), especially gill metabolism. Pearl oysters were exposed to seawater containing 5 mg/L TiO NPs for 14 days, followed by 7 days of recovery in untreated seawater.

Biotemplating technique allows the synthesis of catalysts, recreating the sophisticated structure of nature templates. In this work, some biotemplated TiO semiconductors were synthesized using leaves as templates. Then, g-CN was coupled to materials to later incorporate Pt on the surface or as dopant in the structure to evaluate the efficiency of the solids in two photocatalytic applications to valorize biomass: hydrogen production through glycerol photoreforming, and photoacetalization of cinnamaldehyde with 1,2-propanediol.

Industrial organic dyes represent a significant portion of pollutants discharged into the environment, particularly by the textile industry. These compounds pose serious threats to living organisms due to their high toxicity. Various techniques have been explored for the degradation of organic dyes, among which heterogeneous photocatalysis utilising titanium dioxide (TiO) stands out as a promising technology.

Protein phosphorylation is an important post-translational modification that regulates almost all cellular processes, such as cellular metabolism, growth, differentiation, signal transduction, and gene regulation. Mass spectrometry, which acts as an automated and sensitive method, enables global analysis of protein phosphorylation. However, several technical challenges need to be addressed when analyzing protein phosphorylation in a global manner.

Phosphopeptide enrichment methods based on commercial TiO suffer from difficulties in regulating intermolecular interactions, resulting in low coverage rate and the loss of information on multiphosphorylation sites, thereby limiting comprehensive phosphoproteomic analysis. In this work, MXene TiCT was incorporated into the design of enrichment materials, with its surface structure functionalized and regulated to address the low elution efficiency of TiO for multiphosphorylated peptides. Upon oxidation treatment, the TiCT material formed numerous uniformly distributed TiO nanoparticles on the surface of TiCT-O, providing abundant affinity sites (Ti-O) for selective phosphopeptide enrichment.
