Welcome to the W. M. Keck Center For Nanoscale Optofluidics at UC Santa Cruz.

The W.M. Keck Center for Nanoscale Optofluidics was established with a $1.5 Million grant through the W.M. Keck Center Foundation's Science and Engineering Research Program. Its mission is the development of optofluidic devices and their application to single particle studies in molecular biology and biomedical diagnostics.

Optofluidics is the combination of both integrated optical and fluidic components in the same miniaturized system. The functionalities of optofluidic systems can be improved and expanded by addition of nanoscale features on the chip. The W.M. Keck Nanofabrication facility provides unique capabilities for creating this new type of integrated devices. The Center brings together an interdisciplinary mix of six research groups from five departments at UC Santa Cruz. In both individual and joint research efforts, these groups develop nanoscale optofluidics for fundamental research and biomedical applications.

Our facilities include an FEI Quanta 3D dual beam scanning electron / focused ion beam microscope that is available for general use at competitive recharge rates.
