FluidicsOur ability to fabricate devices on the scale of biological structures and processes opens up a new world of opportunities for interdisciplinary research and biomedical technology.  We are actively developing implantable glucose and ion sensors. These integrated devices contain all necessary power, sensor, and communications systems, and with dimensions around 100um, these represent a new era of personalized medicine, where instant diagnosis and individualized drug administration become possible with continuous blood monitoring. Additionally, these characteristics are ideal for in vivo neural probes, enabling long-term monitoring of complex neural circuits at greatly enhanced resolution, critical for minimizing the risks of neuro surgery while providing a deeper understanding of brain function.  We're also leveraging our expertise in designing microfluidic systems, electronic and optical sensors to develop low-cost, integrated PCR devices in order to provide widely available disease diagnostics to developing nations, targeting areas where proper facilities and trained personel might not otherwise be accessible.
