Three-dimensional (3D) microfluidic structures provide new opportunities for developing novel functional lab-on-a-chip devices. In the past decade, the femtosecond laser direct writing has been developed to become a unique and powerful technology for straightforward fabrication of 3D microfluidic structures in glass. Herein we overview our efforts on femtosecond laser fabrication of three-dimensional microfluidic structures in glass and their lab-on-a-chip applications such as the creation of high-complexity of microfluidic devices and functionalization of microchannels.
