Abstract

Acoustofluidics is a burgeoning field that applies ultrasound to micro-scale to nano-scale fluidic systems. The discovery of the ability to effectively manipulate fluids and particles at small scales has yielded results that are superior to other approaches and has been built into a diverse range of research. Recasting the fundamentals of acoustics from the past to include new phenomena observed in recent years has allowed acoustical systems to impact new areas, such as drug delivery, diagnostics, and enhanced chemical processes. The contributions in this special issue address a diverse range of research topics in acoustofluidics. Topics include acoustic streaming, flows induced by bubbles, manipulation of particles using acoustic radiation forces, fluid and structural interactions, and contributions suggesting a natural limit to the particle velocity, the ability to deliver molecules to human immune T cells, and microdroplet generation via nozzle-based acoustic atomization.

摘要

声流控学是一个新兴的领域，它将超声应用于微尺度到纳米尺度的流体系统。发现能够在小尺度上有效地操纵流体和颗粒的能力已经产生了优于其他方法的结果，并被应用于各种研究中。重新塑造过去声学的基础，包括近年来观察到的新现象，使声学系统能够影响新的领域，如药物输送、诊断和增强化学过程。本期特刊中的贡献涉及声流控学的各种研究课题。主题包括声流、气泡引起的流动、利用声辐射力操纵粒子、流体与结构的相互作用，以及提出粒子速度的自然限制、将分子递送到人类免疫 T 细胞的能力，以及通过基于喷嘴的声雾化生成微滴的贡献。
