Surface acoustic wave (SAW) directed droplet flow in microfluidics for PDMS devices.
نویسندگان
چکیده
We direct the motion of droplets in microfluidic channels using a surface acoustic wave device. This method allows individual drops to be directed along separate microchannel paths at high volume flow rates, which is useful for droplet sorting.

The selective manipulation and incubation of individual picoliter drops in high-throughput droplet based microfluidic devices still remains challenging. We used a surface acoustic wave (SAW) to induce a bubble in a 3D designed multi-trap polydimethylsiloxane (PDMS) device to manipulate multiple droplets and demonstrate the selection, incubation and on-demand release of aqueous droplets from a c...
متن کاملXXII ICTAM, 25–29 August 2008, Adelaide, Australia MODELING CHAOTIC DROPLET ROTATION THROUGH HIGH-FREQUENCY ACOUSTIC EXCITATION
The application of microfluidics to biomedicine has been touted [1] as a means to deliver improved and inexpensive medical care. Though there are many methods for transporting fluids within these devices [2], from the passive capillary forces that draw a fluid along a hydrophilic channel to the actively driven forces like electrophoresis, none would appear to be as powerful as surface acoustic ...
متن کاملFabrication, operation and flow visualization in surface-acoustic-wave-driven acoustic-counterflow microfluidics.
Surface acoustic waves (SAWs) can be used to drive liquids in portable microfluidic chips via the acoustic counterflow phenomenon. In this video we present the fabrication protocol for a multilayered SAW acoustic counterflow device. The device is fabricated starting from a lithium niobate (LN) substrate onto which two interdigital transducers (IDTs) and appropriate markers are patterned. A poly...
متن کاملAcoustothermal heating of polydimethylsiloxane microfluidic system
We report an observation of rapid (exceeding 2,000 K/s) heating of polydimethylsiloxane (PDMS), one of the most popular microchannel materials, under cyclic loadings at high (~MHz) frequencies. A microheater was developed based on the finding. The heating mechanism utilized vibration damping in PDMS induced by sound waves that were generated and precisely controlled using a conventional surface...
