It was found that tea tree oil extract could prevent medical infection

Medical (http://www.chemdrug.com/invest/253/) equipment (http://www.chemdrug.com/sell/22/) usually has a large number of bacteria forming biofilm on the surface In the United States, about 17 million new infections related to bacterial biofilm occur every year, taking 550000 lives About 80% of surgical infections in the world are caused by bacterial biofilm Researchers from Cook University in Australia have developed a technology that enables plant extracts such as tea tree oil (http://www.chemdrug.com/sell/32/) to form polymer coatings on the surface of medical devices to prevent the formation of bacterial biofilm, thus reducing a large number of cases of infection The researchers said that the difficulty in the development of the new technology lies in how to change the plant extract (http://www.chemdrug.com/sell/16/) 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.
