CuO Nanoparticles Reduce Toxicity and Enhance Bioaccumulation of Cadmium and Lead in the Cells of the Microalgae .

The removal of pollutants, including heavy metals, from the aquatic environment is an urgent problem worldwide. Actively developing nanotechnology areas is becoming increasingly important for solving problems in the field of the remediation of aquatic ecosystems. In particular, methods for removing pollutants using nanoparticles (NPs) are proposed, which raises the question of the effect of a combination of NPs and heavy metals on living organisms.

The Conditions Matter: The Toxicity of Titanium Trisulfide Nanoribbons to Bacteria Changes Dramatically Depending on the Chemical Environment and the Storage Time.

In this work, we present an analysis of the antibacterial activity of TiS nanostructures in water and 0.9% NaCl solution suspensions. TiS nanoribbons 1-10 µm long, 100-300 nm wide, and less than 100 nm thick were produced by the direct reaction of pure titanium powder with elemental sulphur in a quartz tube sealed under vacuum.
