A team of French researchers has invented a system for cleaning hospital bacteria. The system is based on titanium dioxide and ultraviolet light. If bacteria come into contact with titanium dioxide and are exposed to ultraviolet rays, they are removed. The dissolution of titanium dioxide in water allows the death of aquatic bacteria easily. But if they are in the air, how to do it to get in touch with titanium dioxide?
To solve the problem, researchers have created a special tube. The tube is filled with glass fingers, which considerably increases the surface. The tube is subjected to ultraviolet rays and passes the air through the tube. It seems that all bacteria come into contact with titanium dioxide, which causes their death. At the moment it has been tested with Escherichia coli, but also wants to try Legionella neumophila, which generates serious health problems in hospitals.
