Nanoparticles fight bacterial infections

Researchers from the University of New South Wales (Australia) have come up with a new way to combat biofilms - the accumulation of harmful bacteria. Studies show that up to 80% of pathogenic infections occur in biofilms. They often enter the human body through infected medical equipment and instruments.

Australian scientists have made significant progress in overcoming this problem. As a guinea pig, they used Pseudomonas aeruginosa, a dangerous human pathogen.

Before starting to influence the biofilm, scientists tried to recreate the behavior of cells at the time of their capture of "new territories". At this moment, a single cellular structure disintegrates into separate fragments, which makes it vulnerable to external influences.

To this end, researchers began to introduce iron oxide nanoparticles, simultaneously heating them by the action of an electromagnetic field. In this case, the temperature rises by 5 degrees, which leads to the destruction of the biofilm. As a result, scattered bacteria are easier to treat.
