New low-cost method to produce light-based lab-on-a-chip devices for fast medical tests
(PHYSorg.com Physics)

A new fabrication process could make it easier and less expensive to incorporate optical sensing onto lab-on-a-chip devices. These devices integrate laboratory functions onto a plastic or glass `chip` typically no more than a few square centimeters in size, allowing automated testing in the doctor`s office or various types of chemical or biological analysis with portable instruments.
