The high throughput deposition of microscale objects with precise spatial arrangement
represents a key step in microfabrication technology. This can be done by creating physical …

The ability to trap precise quantities of cells or particles into confined areas has numerous
applications for biological purposes. In particular, single cell trapping has received …

An electronically controlled acoustic tweezer was used to demonstrate two acoustic
manipulation phenomena: superposition of Bessel functions to allow independent …

We present the analytical design and experimental realization of a scheme based on multi-
arm coiling slits to generate the stable acoustic vortices in a broadband. The proposed …

The use of ultrasonic fields to manipulate particles, cells and droplets has become
widespread in lab on a chip (LOC) systems. There are two dominant actuation methods, the …

In this study, a method to separate particles, within a small sample, based on size is
demonstrated using ultrasonic actuation. This is achieved in a fluid, which has been …

Ultrasound noncontact particle manipulation (NPM) is based on the acoustic radiation force
associated with an ultrasound wave field, and enables a myriad of engineering applications …

The asymmetric generation of acoustic vortex refers to the physical characteristics that pass
the generated acoustic vortex in one direction while blocking it in the opposite direction …

We use ultrasound directed self-assembly to organize particles dispersed in a fluid medium
into a three-dimensional (3D) user-specified pattern. The technique employs ultrasound …

Acoustic levitation in air has applications in contactless handling and processing. Here a first-
order Bessel function-shaped acoustic field, generated using an 8-element circular array …
