Nanoparticle sensor (IMAGE)
Caption
MIT engineers have designed a new nanoparticle sensor that can enable cancer diagnosis with a simple urine test. The nanoparticles (blue) carry DNA barcodes (zigzag lines) that can be cleaved by cancer-associated proteases in the body (pac-man shapes). Once cleaved, the DNA barcodes can be detected in a urine sample.
