Electronic Textiles Being Made
Textiles coated with carbon nanotubes form electronic sensors that look and feel like ordinary cotton.
When antibodies to human albumin are added to the nanotube solution, the treated threads can sensitively detect blood. In a solution containing a small amount of human blood (dye added for visual emphasis), the thread becomes much less resistant to the flow of electrical current. A solution with just a tiny amount of albumin in it causes the thread’s resistance to drop significantly.
