Acoustofluidic Sorters The cover image depicts the design of an acoustofluidic droplet sorter based on single phase focused transducers. In the droplet sorter, the droplets sequentially flow through a tapered channel where an optical fiber pair detects fluorescence signals and then, according to the fluorescence information, pulse acoustic signals are generated to trigger the single‐phase focused transducers. The droplet is manipulated by standing surface acoustic waves and guided to the collection outlet if identified as a cell‐laden droplet. Otherwise, the droplet maintains its route to flow into the waste outlet. More information can be found in article number 2103848 by Tania Konry, Tony Jun Huang, and co‐workers.
