Water Processing: Light Helps Degrade Hormones
Karlsruhe Institute of Technology (KIT)

Micropollutants in water often are hormones that accumulate in the environment and may have negative impacts on humans and animals. Researchers of Karlsruhe Institute of Technology (KIT) and Leibniz Institute of Surface Engineering (IOM) in Leipzig have now developed a process for the photocatalytic degradation of these pollutants when they flow through polymer membranes. It is presented in Nature Nanotechnology. Irradiation with light triggers a chemical reaction, as a result of which steroid hormones are degraded on the membranes coated with titanium dioxide.

American Institute of Physics (AIP)

One recent obstacle to drug delivery research is an observed weak correlation between in vitro and in vivo performance. When nanoparticles are applied intravenously, they face several obstacles that differ from in vitro situations. Nanoparticles are usually covered by a biomolecular multilayer (a protein corona), which alters the physiochemical properties, pharmacokinetics, and toxicity profile of the nanoparticles. In Biophysics Reviews, researchers provide a cutting-edge characterization of the protein corona formed around nanoparticles and its impact on the physiochemical and biological properties of these nanoparticles.
