Implementation of two-dimensional selective acoustic tweezers merely using four straight interdigitated transducers:a numerical proof of concept of radiation field synthesis by pulsed acoustic waves
Shuhan Chen, Jia Zhou, Antoine Riaud
Selective acoustic tweezers can focus the acoustic radiation force on a single particle to manipulate it without affecting its neighbors. This has long required highly complex hard…
Numerical simulation of the radiation force from transient acoustic fields: Application to laser-guided acoustic tweezers
Shuhan Chen, Qing Wang, Qi Wang +2
Using pulsed acoustic waves could provide a superior selectivity for microscale acoustic tweezers. However, the theory for the radiation force of pulsed acoustic waves has only bee…
Skipping the boundary layer: high-speed droplet-based immunoassay using Rayleigh acoustic streaming
Qi Wang, Zhe Ding, Gary Wong +2
Acoustic mixing of droplets is a promising way to implement biosensors that combine high speed and minimal reagent consumption. To date, this type of droplet mixing is driven by a…
Laser-guided acoustic tweezers
Qing Wang, Shuhan Chen, Jia Zhou +1
Acoustic tweezers can manipulate microscopic objects and cells independently of the optical, magnetic and electrical properties of the objects or their medium. However, because ult…
