A glass lab-on-a-chip.
Sound waves instead of electromechanical valves control the droplets
Researchers at the University of Michigan have succeeded in developing a chip used to conduct experiments on fluids which is driven by sound rather than electromechanical valves. This approach to controlling "lab-on-a-chip" devices could be a big step forward in reducing costs and complexity in areas ranging from chemical analysis to environmental monitoring, potentially leading to innovations like handheld devices you could sneeze onto to find out if you have the flu.
