Using X-ray photoelectron spectroscopy - a technique used to examine the surface chemistry of a solid material - researchers have begun to understand the operating principles and sensing mechanisms behind promising nanocomposite thin film materials.
Scientists are investigating the use of nanoparticles as a way to disinfect wounds. It could prove to be much more effective than existing techniques because the particles would be tiny enough to enter the skin via hair follicles, ensuring much better penetration of the area affected by surgery.
Chemists have developed a novel type of firefighting foam based on inorganic silica nanoparticles. The new foam beats existing analogues in fire extinguishing capacity, thermal and mechanical stability and biocompatibility.
