What is it about?
The review paper discussion of droplet acoustofluidic techniques for essential unit operations, such as droplet generation, separation, merging, splitting, steering, trapping, in-droplet sample manipulation, sample control within sessile droplets, and digital acoustofluidics.

Why is it important?
Acoustofluidic methods are widely recognized for the ability to manipulate droplets suspended in a continuous fluid in a label-free, non-contact, and biocompatible manner. Droplet-based acoustofluidics can be broadly categorized into three main types: continuous-flow droplet acoustofluidics, sessile droplet acoustofluidics, and digital droplet acoustofluidics. This review focuses on these three categories— collectively referred to as droplet-based acoustofluidics—while excluding platforms such as jetting and atomization acoustofluidics.
Perspectives
As a researcher actively developing acoustofluidic platforms, I am particularly excited by the transformative potential of droplet manipulation techniques highlighted in our recent review. Acoustofluidics has rapidly evolved into a powerful platform for microscale droplet manipulation, offering impressive precision and versatility. As acoustofluidic technologies continue to mature, the insights presented here are intended to guide future research efforts toward more integrated, programmable, and application-specific platforms that will drive forward innovations in biology, chemistry, and medicine.
