Micro Pac-Man. (Prototype).(nanotechnology device interacts with red blood cells)(Brief Article)

From: Poptronics | Date: February 1, 2002 | Copyright information

Researchers at Sandia National Laboratories have developed a micromachine that interacts with red blood cells. In less than a blink of an eye, its tiny silicon "teeth" open and close like jaws in a channel about one-third the width of a human hair. Think Pac-Man gobbling down those little dots. The upper teeth of the microdevices slide back and forth across the microchannel to momentarily capture individual red blood cells across the lower teeth. When the jaws close, they trap and disfigure one of the many red blood cells being pumped through the microchannel. when they let loose ...
