 This is Scientific American’s 60-Second Science. I’m Gretchen Cuda Kroen. Got a minute?


 
Nasty bacteria cling to the surfaces of countertops. They also stick to medical devices - like catheters - that are placed inside the human body, where they can become a dangerous source of infection.
 
Individually, bacteria are fairly easily killed. But if they multiply on a surface, they eventually form a biofilm - a tightly organized bacterial 1 community that can fight off antibiotics 3 and the body’s immune system.
 
Now, researchers have come up with a way to give those nasty bugs 4 the “slip(贴条子;禁停)” - a non-stick surface that stops the biofilm from forming. The material hasn’t been tested in humans yet. But in the lab, catheters coated with the non-stick surface stayed almost completely free of staphylococcus aureus bacteria(金黄色葡萄球菌). The findings were presented at the October, 2012, AVS International symposium 5 in Tampa, which covers materials, interfaces 6 and processing. 
 
By denying bacteria a grip(附着) on medical devices without resorting to antibiotics, the researchers also hope to help doctors get a grip(掌控) on antibiotic 2 resistance - one of medicine’s stickiest problems.
