"Nanocarpet" Changes Color, Kills Bacteria

Such carpeting would be useful in environments that demand exceptional cleanliness, such as hospitals and homes of people with immune deficiencies, or high-security areas as an early-warning system for bioterrorist attack. It would also be interesting to couple nanocarpet with pressure-sensitive robotic "skin" that detects pressure through a grid of sensors. Could a nanocarpet be engineered to clean itself, to dry itself, to change colors along with decor, and even to repair itself?
Also, from Beverly Tang's reBlog, this same team is working to develop "nano-paint" with similar color-change and antiseptic properties.
