Nanoparticle Removal Chip

Designing nanoparticles to deliver drugs is easier than figuring out how to extract them from the blood stream to see if and how well they worked. To address this engineers at the University of California San Diego designed a dime-sized device that created oscillating electric fields—15,000 oscillations/second—which causes momentary charge imbalances in the particles that allow them to move out of the blood plasma and toward the device’s hundreds of electrodes. The separation happens in minutes. MORE
