Advances in microchip technology may someday enable clinicians to perform tests for hundreds of diseases—sifting out specific molecules, such as early stage cancer cells—from just one drop of blood. But fabricating such "lab-on-a-chip" designs—tiny, integrated diagonistic sensor arrays on surfaces as small as a square centimeter—is a technically challenging, time-consuming and expensive feat.
