AI Article Synopsis
- The study introduces a new acoustofluidic platform that utilizes surface acoustic waves (SAWs) to easily capture and release droplets in microwells.
- By adjusting the applied AC signal, the position of the SAW can be controlled to either push droplets into the microwells or pull them out.
- This technology allows for selective capture and release of droplets, providing a precise method for handling fluid samples in microchannels.
Article Abstract
We demonstrate an acoustofluidic platform that uses surface acoustic waves (SAWs) for the facile capture of droplets inside microwells and their on-demand release. When the ac signal applied to the device is tuned to modulate the location of the SAW, the SAW-based acoustic radiation force retracts or pushes the droplets into or out of one of three microwells fabricated inside a microchannel to selectively capture or release the droplet.
