Dr Per Augustsson, Biomedical Engineering, Lund University will give a lecture.

 

List of topics:

  • Acoustic biophysical size-independent gating
  • Acoustic size-separation of sub-micron particles
  • Packing blood cells by sound

 

Abstract:

Sound carries energy and exerts forces on fluids and suspended objects through scattering and attenuation. Acoustophoresis, where microscopic particles are separated while flowing through a transverse acoustic standing wave field, have received an increased interest in the biomedical field. I study ultrasound-induced (re)-organization of miscible liquids of inhomogeneous density and compressibility inside microfluidic acoustic standing wave resonators. I will present how such systems enables size-independent separation and biophysical gating of cells based on their acoustic scattering properties. I will describe how flow-laminated inhomogeneous media can be employed to achieve flow-through acoustic separation of sub-micrometer particles and how blood cells become densely packed when whole blood is exposed to ultrasound.
