A device with built-in “speed bumps” could be used to detect cancerous cells in blood samples or to sort microscopic particles for various industrial purposes, its developers say.

The lab-on-chip platform, also known as a microfluidic device, is powered in its simplest form by gravity, though other forces like magnetism can also be used.

By pouring a liquid, like blood, past a series of micron-scale-high diagonal ramps—similar to speed bumps on a road—the device causes microscopic material to separate into discrete categories, based on weight, size, or other factors.
