Research update: New microchip sorts white blood cells from whole blood Device may be used to quickly detect signs of sepsis, other inflammatory diseases.

Early in 2012, MIT scientists reported on the development of a postage stamp-sized microchip capable of sorting cells through a technique, known as cell rolling, that mimics a natural mechanism in the body.

The device successfully separated leukemia cells from cell cultures — but could not extract cells directly from blood.

Now the group has developed a new microchip that can quickly separate white blood cells from samples of whole blood, eliminating any preliminary processing steps — which can be difficult to integrate into point-of-care medical devices.  Read more...
