Three-dimensional splitting microfluidics.

Holographic fabrication of three-dimensional nanostructures for microfluidic passive mixing.

In this study, we incorporated mixing units of three-dimensional (3D) interconnected pore network inside microfluidic channels by combining single prism holographic lithography and photolithography. 3D pore network structures were generated by the interference of four laser beams generated by a truncated triangular pyramidal prism. The levelling between the 3D porous structures and the channel ...

Three-dimensional surface microfluidics enabled by spatiotemporal control of elastic fluidic interface.

As an emerging alternative to the conventional counterpart, surface microfluidics incorporates both intrinsic resistive solid-liquid and elastic frictionless gas-liquid interfaces, leading to unique flow-pressure characteristics. Furthermore, the open-surface microfluidic platforms can be fabricated on a monolithic substrate with high wettability contrast by the previously reported one-step lit...

Fabrication of three-dimensional SU-8 microchannels by proton beam writing for microfluidics applications: Fluid flow characterisation

Deterministic splitting of fluid volumes in electrowetting microfluidics.

Conventional droplet generation approaches in digital microfluidics show ~10% variation in droplet volumes and are restricted to creating only small volumes. In this work, we demonstrate a new approach for splitting sample volumes precisely by gradually ramping down voltage, in place of abruptly switching off electrodes. This allows us to eliminate hydrodynamic instabilities responsible for var...
