“…Factors contributing to diffraction include scattering by the electrodes within the IDT, the ratio of the IDT aperture to the acoustic field wavelength, and the propagation distance [34,72,73]. Each finger electrode acts as a scattering source for the acoustic wave, and high-frequency IDTs, which contain a larger number of finger electrodes than low-frequency IDTs, are more susceptible to diffraction [74,75]. To inhibit diffraction-induced peripheral vortices, one conventional solution is to widen the aperture, thus generating broader areas where the acoustic radiation force is dominant.…”

Acoustofluidics, an interdisciplinary nexus of microfluidics and acoustics, is propelling the critical functionalities of manipulation, separation, and mixing within microscale environments. This integration leverages the accuracy of microfluidics with the manipulation capabilities of acoustics, thereby enhancing the vital sample processing steps and satisfying inquiries in experiments. To fulfill the requisites of practical application in clinical and research arenas, the evolution of acoustofluidics concentrates on accomplishing finer particle separation, instantaneous manipulation, and augmented integration capacity. Acoustofluidics has evolved into a sophisticated and versatile instrument for handling specimens and reactants, prompting a trend towards devices characterized by stable performance at elevated frequencies, programmable control, and seamless integration with auxiliary microfluidic systems. In this review, we present the latest advancements in the development of sophisticated acoustofluidic systems that enhance efficiency and enable precise modulation of performance across spatial and temporal scales, thereby extending their functionality and suitability for practical applications.
