Researchers at Cook University in Australia have developed a technology that allows plant extracts such as tea tree oil to form polymer coatings on medical devices to prevent bacterial biofilm formation, thereby reducing the number of cases of infection According to Jacob, the leader of the research project, there are usually a large number of bacteria forming biofilm on the surface of medical equipment About 17 million new cases of bacterial biofilm related infections occur in the United States every year, taking 550000 lives About 80% of the global surgical infections are caused by bacterial biofilm Jacobs said that the difficulty in the development of the new technology lies in how to change the plant extract from liquid to solid, form a coating on the surface of medical equipment, and do not affect the antibacterial performance With the help of plasma enhanced technology, the steam of plant essential oil in the reactor can be solidified on the surface of medical equipment to form a coating with biological activity The results show that the coating has good antibacterial properties The main advantage of the new technology is that no chemicals such as solvents are used in the manufacturing process, so the coating has no potential chemical hazards and will not damage the medical equipment itself, the researchers said The coating has light permeability, which means it can be used in contact lenses, aquatic biological sensors and so on.
