Facile and Controlled Integration of Functional Nanosturctures in Microfluidic Device

Nanostructure integration within microfluidic device has a great potential for substantial improvement of performance and widening of applications by taking advantages of unique nanoscale material properties. We introduce a novel and simple method for the integration of functional nanowires by controlled hydrothermal reaction within microfluidic device. By modulating synthesis parameters such as reaction seeds, temperatures, periods, and heating locations, the morphology and location of synthesized nanowires can be well-controlled. We also demonstrate a preliminary result of pH sensing experiment by using the ZnO nanowire bridges fabricated by this method.
