Dynamically tunable multispot optofluidic waveguide.
Novel technology combines high-performance microfluidics for sample processing with dynamic optical tuning and switching, all on a low-cost “chip” made of a flexible silicone material. In previous devices from Schmidt’s lab, optical functions were built into silicon chips using the same fabrication technology used to make computer chips. The new device is made entirely of polydimethylsiloxane (PDMS), a soft, flexible material used in microfluidics as well as in products such as contact lenses and medical devices.
“We can use this fabrication method now to build an all-in-one device that allows us to do biological sample processing and optical detection on one chip,” said Schmidt, the Kapany Professor of Optoelectronics and director of th...
