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. It has a flexible design so that it could be used for a wide range of diagnostics.
Much research in recent years has focused on the chemical and medical possibilities of so-called microfluidic devices at the heart of lab-on-a-chip designs.
These microfluidics contain between dozens and thousands of tiny channels through which fluids can flow, and as micro-manufacturing methods have advanced, so has the potential complexity of microfluidics.
Now, scientists at IBM’s research labs in Zurich have developed a cheap lab-on-a-chip that has the potential to diagnose dozens of diseases.
