Three-dimensional (3D) culture of multicellular spheroids, offering a desirable biomimetic
microenvironment, is appropriate for recapitulating tissue cellular adhesive complexity and …

The ability to manipulate microscale and nanoscale particles is highly desirable for various
applications ranging from targeting drug delivery to additive manufacturing. Here we report …

Contactless manipulation of particles and cells using sound radiation forces that can be
tuned and adjusted in real time has become important in various applications. These …

In this letter, we show that a particle in liquid can be pulled backward by simply launching
two crossed acoustic plane waves at it. It is demonstrated that the counterintuitive pulling …

Acoustic manipulation has been a topic of significant research in recent years. However, the
trapping scale in the radiative acoustic field domain is severely limited by the diffraction limit …

Effective sound energy transmission and beam manipulation through stiff and dense
materials such as metal remain daunting tasks. It is in part attributable to the vast impedance …

Accurate rotation of microparticles is of great significance in micro-rotors, multi-angle
microscopic observation, microbial three-dimensional phenotyping, and microsystem …

Efficient and controllable gene/drug delivery triggered by sonoporation is critical to cellular
therapy. This study reports on repairable sonoporation for massive cells trapped on a …

In this letter, we present experimental demonstration of multi-particles trapping and
patterning by the artificially engineered acoustic field of phononic crystal plate. Polystyrene …

The interaction between harmonic plane progressive acoustic beams and a pulsating
spherical radiator is studied. The acoustic radiation force function exerted on the spherical …
