The relevant length scales in sub-nanometer amplitude surface acoustic wave-driven acoustic streaming are demonstrated. We demonstrate the absence of any physical limitations preventing the downscaling of SAW-driven internal streaming to nanoliter microreactors and beyond by extending SAW microfluidics up to operating frequencies in the GHz range. This method is applied to nanoliter scale fluid mixing.

Background And Objectives: Acoustofluidic manipulation of particles and biological cells has been widely applied in various biomedical and engineering applications, including effective separation of cancer cell, point-of-care diagnosis, and cell patterning for tissue engineering. It is often implemented within a polydimethylsiloxane (PDMS) microchannel, where standing surface acoustic waves (SSAW) are generated by sending two counter-propagating ultrasonic waves on a piezoelectric substrate.
Methods: In this paper, we develop a full cross-sectional model of the acoustofluidic device using finite element method, simulating the wave excitation on the substrate and wave propagation in both the fluid and the microchannel wall.

In this work, a new method to enhance the sensing response of an ultrasonically catalyzed metal oxide gas sensor has been proposed and developed, in which pulse ultrasound is employed to enhance the redox reaction at the sensing surface. It is experimentally confirmed that with a proper pulse width, the negative effect of acoustic streaming on the ultrasonic enhancement process can be effectively suppressed. Comparing the steady responses of five target gases under the pulse and continuous ultrasound, respectively, it is found that the pulse ultrasound causes a better catalysis effect, and response enhancement (RE) by the pulse ultrasound with an optimal pulse width depends on the ultrasonic strength as well as the species and concentration of the target gas.

Acoustic waves are a possible reusable method to extinguish flames. Previous studies have placed the sound source near the flame or have used standing waves to reach large enough acoustic amplitudes to extinguish it. In this study, a new method is explored: using time reversal in a room to focus transient acoustic waves to the flame to extinguish it.

The generation of surface acoustic waves (SAW) through electrically driven piezoelectric devices has attracted considerable attention in both fundamental research and practical applications, particularly for suppressing bacterial adhesion on surfaces. However, the precise mechanism by which SAW prevents bacterial attachment remains incompletely understood. This study explores the impact of SAW-induced boundary-driven streaming on the surface adhesion of and in a liquid environment, focusing on the prevention of bacterial adhesion through the formation of micrometer-scale shielding fluid layers.

Red blood cell (RBC)-based carriers have emerged as promising vehicles for drug delivery due to their inherent biocompatibility and biodegradability. Traditional methods for loading nanoparticles (NPs) onto RBC surfaces often involve labor-intensive processes like incubation and multiple centrifugation steps, limiting their practicality and controllability. In this study, we introduce a fully integrated acoustofluidic platform that enables one-step preparation of NP-loaded RBC carriers with controlled modification and on-site purification.
