Tiny chip could diagnose disease
Researchers have demonstrated a tiny chip based on silicon that could be used to diagnose dozens of diseases.
A tiny drop of blood is drawn through the chip, where disease markers are caught and show up under light.
The device uses the tendency of a fluid to travel through small channels under its own force, instead of using pumps.
The design is simpler, requires less blood be taken, and works more quickly than existing "lab on a chip" designs, the team report in Lab on a Chip.
