Warp Speed -- And Watch Out for That Artery

Scientists developing monitoring devices to fit into astronauts' white blood cells

FRIDAY, July 19, 2002 (HealthDayNews) -- University of Michigan researchers are boldly going where no scientists have gone before.

The researchers, working with a $2 million, 3-year grant from NASA, are trying to develop devices called nanosensors that fit inside astronauts' white blood cells and detect early signs of damage from radiation or infection.

The nanosensors, spheres created from synthetic polymers, have a diameter of less than 5 nanometers. One nanometer is one-billionth of a meter and a million nanometers are about the size of a pinhead.

The idea is to include special fluorescent tags that glow when exposed to proteins associated with cell death.
