摘要
Integration of functional nanostructures within a microfluidic device can synergize the advantages of both unique properties of nanomaterials and diverse functionalities of microfluidics. In this paper, we report a novel and simple method for the in situ synthesis and integration of ZnO nanowires by controlled hydrothermal reaction within microfluidic devices. By modulating synthesis parameters such as the seed preparation, synthesis time, and heating locations, the morphology and location of synthesized nanowires can be easily controlled. The applications of such nanostructure-integrated microfluidics for particle trapping and chemiresistive pH sensing were demonstrated.
