Abstract
We demonstrate a microfluidic mixer of high mixing efficiency in fused silica substrate using femtosecond laser-induced wet etching and hydroxide-catalysis bonding method. The micromixer has a three-dimensional geometry, enabling efficient mixing based on Baker's transformation principle. The cross-sectional area of the fabricated micromixer was 0.5 × 0.5 mm2, enabling significantly promotion of the throughput of the micromixer. The performance of the fabricated micromixers was evaluated by mixing up blue and yellow ink solutions with a flow rate as high as 6 mL/min.

Abstract
In the pursuit of modern microfluidic chips with multifunction integration, micronanofabrication techniques play an increasingly important role. Despite the fact that conventional fabrication approaches such as lithography, imprinting and soft lithography have been widely used for the preparation of microfluidic chips, it is still challenging to achieve complex microfluidic chips with multifunction integration. Therefore, novel micronanofabrication approaches that could be used to achieve this end are highly desired. As a powerful 3D processing tool, femtosecond laser fabrication shows great potential to endow general microfluidic chips with multifunctional units. In this review, we briefly introduce the fundamental principles of femtosecond laser micronanofabrication. With the help of laser techniques, both the preparation and functionalization of advanced microfluidic chips are summarized. Finally, the current challenges and future perspective of this dynamic field are discussed based on our own opinion.

Abstract
A microfluidic device is presented that performs electrophoretic separation coupled with fraction collection. Effluent from the 3.5 cm separation channel was focused via two sheath flow channels into one of seven collection channels. By holding the collection channels at ground potential and varying the voltage ratio at the two sheath flow channels, the separation effluent was directed to either specific collection channels, or could be swept past all channels in a defined time period. As the sum of the voltages applied to the two sheath flow channels was constant, the electric field remained at 275 V/cm during the separation regardless of the collection channel used. The constant potential in the separation channel allowed uninterrupted separation for late-migrating peaks while early-migrating peaks were being collected. To minimize the potential for carryover between fractions, the device geometry was optimized using a three-level factorial model. The optimum conditions were a 22.5° angle between the sheath flow channels and the separation channel, and a 350 μm length of channel between the separation outlet and the fraction channels. Using these optimized dimensions, the device performance was evaluated by separation and fraction collection of a fluorescently-labeled amino acid mixture. The ability to fraction collect on a microfluidic platform will be especially useful during automated or continuous operation of these devices or to collect precious samples.
