One of the long held hopes for DNA sequencing is that it will usher in an era of personalized, predictive medicine by providing individualized blueprints of genetic predispositions for specific conditions and diseases, such as cancer, diabetes and addiction. Researchers have now devised a method that works at a very small scale to sequence DNA quickly and relatively inexpensively that could open the door to more effective individualized medicine.
