Fast Inertial Microfluidic Actuation and Manipulation Using Surface Acoustic Waves
Though uncommon in most microfluidic systems due to the dominance of viscous and capillary stresses, it is possible to drive microscale fluid flows with considerable inertia using surface acoustic waves (SAWs), which are nanometer order amplitude electro-elastic waves that can be generated on a piezoelectric substrate. Due to the confinement of the acoustic energy to a thin localized region alo...
متن کاملMicrofluidic on-demand droplet merging using surface acoustic waves.
Individual droplets can be isolated within microfluidic systems by use of an immiscible carrier layer. This type of two phase systems, often termed "digital microfluidics", find wide ranging applications in chemical synthesis and analysis. To conduct on-chip biochemical analysis, a key step is to be able to merge droplets selectively in order to initiate the required reactions. In this paper, a...
متن کاملLocalized Induction of Cortical Spreading Depression Waves in Brain Slices Using Microfluidic Injection
Advanced in vitro experimental tools for locally stimulating and probing brain slices can greatly facilitate systematic studies of neuronal phenomena and rapid drug screening. A major challenge in developing such tools is to achieve precise spatial and temporal control of local chemical environments of brain slices while maintaining their viability. This paper reports an improved design of a br...
متن کاملBurgers shock waves and sound in a 2D microfluidic droplets ensemble.
We investigate the collective motion of a two-dimensional disordered ensemble of droplets in a microfluidic channel far from equilibrium and at Reynolds number approximately 10(-4). The ensemble carries ultraslow shock waves and sound, propagating at approximately 100 microm s(-1) and superposed on diffusive droplets motion. These modes are induced by long-range hydrodynamic dipolar interaction...
متن کاملContinuous particle separation in a microfluidic channel via standing surface acoustic waves (SSAW).
This work introduces a method of continuous particle separation through standing surface acoustic wave (SSAW)-induced acoustophoresis in a microfluidic channel. Using this SSAW-based method, particles in a continuous laminar flow can be separated based on their volume, density and compressibility. In this work, a mixture of particles of equal density but dissimilar volumes was injected into a m...
