Mean-acoustic fields exerted on a subwavelength axisymmetric particle
Everton B. Lima, Glauber T. Silva
The acoustic radiation force produced by ultrasonic waves is the "workhorse" of particle manipulation in acoustofluidics. Nonspherical particles are also subjected to a mean torque…
Raman-acoustofluidic integrated system for single-cell analysis
Harrisson D. A. Santos, Amanda E. Silva, Giclênio C. Silva +8
Confocal Raman microscopy offers a particular pathway for monitoring chemical "fingerprints" of intracellular components like the cell membrane, organelles, and nucleus. Neverthele…
Acoustic radiation force and torque on spheroidal particles in an ideal cylindrical chamber
Jose P. Leao-Neto, Mauricio Hoyos, Jean-Luc Aider +1
We theoretically investigate how the acoustic radiation force and torque arise on a small spheroidal particle immersed in a nonviscous fluid inside an ideal cylindrical chamber. Th…
Acoustic spin transfer to a subwavelength spheroidal particle
Jose H. Lopes, Everton B. Lima, Jose P. Leao-Neto +1
We demonstrate that the acoustic spin of a first-order Bessel beam can be transferred to a subwavelength (prolate) spheroidal particle at the beam axis in a viscous fluid. The indu…
Subwavelength beam focusing using a ball-shaped lens for ultrasound imaging
Victor H. S. Santos, Everton B. Lima, Andre L. Baggio +2
Ultrasonic superresolution images can be generated by means of (super) focusing acoustic beams to subwavelength dimensions or using algorithm-based methods. Here, we demonstrate th…
Acoustic radiation torque exerted on a subwavelength spheroidal particle by a traveling and standing plane wave
Jose P. Leao-Neto, Jose H. Lopes, Glauber T. Silva
The nonlinear interaction of ultrasonic waves with a nonspherical particle may give rise to the acoustic radiation torque on the particle. This phenomenon is investigated here cons…
