This close-up of a microfluidic
memory shows two types of fluid as they move through the chip. Light-colored
fluid enters from the right and exits through the channel at the bottom.
The dark-colored fluid enters from the narrow channel on the left
and exits through the channel at the top. A sharp, momentary increase
in pressure through the narrow channel switches the outflows, which
can represent binary numbers.
