Daniel Taylor, environmental services supervisor at the University of Vermont Medical Center, wheels a Xenex Germ-Zapping Robot into a patient room at the hospital and positions a motion sensor to shut it down if anyone enters the room.
The Xenex strongly resembles Star Wars’ R2D2, except it doesn’t beep, whistle or scream, and its sole purpose is to kill bacteria by destroying their DNA with ultraviolet light. Taylor switches the robot on and leaves, closing the door behind him as intense flashes of blue light begin steadily pulsing through the room.
In 15 minutes, the room will be sterile. All bacteria, including the stubborn and dangerous C. diff and MRSA strains, will be dead.
