Abstract
The development of detachable acoustofluidic devices is of great significance for disposable and cost-effective biological and chemical analysis. In this work, a highly integrated holographic acoustofluidic device based on acoustic holography and microfluidic chips was proposed to realize the modulation of striped acoustic field in microchannels. In the device, the chip is disposable and the transducer is reused. The acoustic hologram was fabricated by injection molding for efficient manufacturing and low cost. In addition, a multiphysics simulation model for holographic acoustofluidic chip was established to analyze the effect of acoustic field modulation and particle manipulation. Results showed that the acoustic pressure inside the microchannel of the device exhibits a clear striped distribution, and a linear arrangement of particles parallel and inclined to the extension direction of the channel wall can be achieved within 2 s. The distance between the arrangement lines in the target region was controlled at around 60 μm. The investigation of thermal effect validates the biocompatibility. The designed holographic acoustofluidic device presents a promising option for the manipulation, arrangement, and sorting of cells and other particles in microchannels.
期刊介绍:
Since its launch in 1968, Applied Acoustics has been publishing high quality research papers providing state-of-the-art coverage of research findings for engineers and scientists involved in applications of acoustics in the widest sense.
Applied Acoustics looks not only at recent developments in the understanding of acoustics but also at ways of exploiting that understanding. The Journal aims to encourage the exchange of practical experience through publication and in so doing creates a fund of technological information that can be used for solving related problems. The presentation of information in graphical or tabular form is especially encouraged. If a report of a mathematical development is a necessary part of a paper it is important to ensure that it is there only as an integral part of a practical solution to a problem and is supported by data. Applied Acoustics encourages the exchange of practical experience in the following ways: • Complete Papers • Short Technical Notes • Review Articles; and thereby provides a wealth of technological information that can be used to solve related problems.
Manuscripts that address all fields of applications of acoustics ranging from medicine and NDT to the environment and buildings are welcome.
