Blood fractionation is a key pre-treatment prior to analysis steps in the field of immunology and diagnostics. In this thesis, a microfluidic technique called acoustophoresis is evaluated for plasma generation as well as for separation of white blood cells from whole blood.
Keywords: acoustophoresis; secondary acoustic radiation forces; cell manipulation 1. Introduction Particle and cell manipulation by utilizing the acoustic radiation force has been extensively investigated [1–7]. The source of this manipulation is the sound wave scattered from suspended

Our developments of acoustophoresis in these clinical areas also targets the removal of trombocytes from apheresis products and production of WBC-free trombocyte fractions. A recent key development was the demonstration that high performance acoustophoresis can be performed in standard The acoustophoresis subsequently translates the beads into a stream of uncoloured buffer in the channel centre (continuous flow bead washing). Washed beads exit via the central outlet. Acoustophoresis is a very attractive, gentle label-free and noncontact method of particles and cell manipulation/separation due to its induced motion when subjected to an acoustic field.
acoustophoresis (uncountable) acoustic levitation ; a method for suspending matter in a medium by using acoustic radiation pressure from intense sound waves in the medium 2015 November 12, “Cancer Cell Analyses at the Single Cell-Level Using Electroactive Microwell Array Device”, in PLOS ONE [1] , DOI : 10.1371/journal.pone.0139980 : Acoustic levitation is a method for suspending matter in air against gravity using acoustic radiation pressure from high intensity sound waves. It works on the same principles as acoustic tweezers by harnessing acoustic radiation forces.

Acoustophoresis of disk-shaped particles. Unlike acoustophoresis of spherical particles, acoustophoresis of disk-shaped particles causes an acoustic radiation
In silicon microdevices, water-in-oil droplets of 200 μm size were generated for a set of unit operations including droplet fusion, focusing, sorting and medium exchange around 0.5-1 MHz acoustic frequency. Using a previously-well-tested numerical model, we demonstrate that good acoustophoresis can be obtained in a microchannel embedded in an acoustically soft, all-polymer chip by excitation of whole-system ultrasound resonances. Provided herein are systems and methods for separation of particulate from water using ultrasonically generated acoustic standing waves.

Introduction Particle and cell manipulation by utilizing the acoustic radiation force has been extensively investigated [1–7]. The source of this manipulation is the sound wave scattered from suspended KEYWORDS: Acoustophoresis, Frequency modulation, Acoustic energy density, Microchannel INTRODUCTION Microchannel acoustophoresis is a powerful and well-investigated method for particle and cell manipulation in lab-on-a-chip devices [1]. The standard actuation method in acoustophoresis is to operate the ultrasound transducer at a acoustophoresis) has gained significant momentum due to its many advantages, such as non-invasiveness, versatility, simple fabrication, easy operation, and convenient integration with other on-chip units.

2019-01-01 · Acoustophoresis can be applied as continuous flow acoustophoresis or affinity-bead-based acoustophoresis. In continuous flow acoustophoresis, standing-wave fields perpendicular to the flow of particles containing liquid suspension allow particles to move toward nodes or antinodes.
