Engineers from Rhode Island’s Brown University have applied coatings of selenium nanoparticles to pieces of polycarbonate – the material used for things like catheters and endotracheal tubes – and then exposed those samples to Staphylococcus aureus bacteria. In some cases, populations of the bacteria were subsequently reduced by up to 90 percent... Continue Reading Selenium shows promise as antibiotic coating for medical devices
