3. 2. Improving cell secretome analysis and bacteria evolution by means of acoustophoresis

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Moritz Leuthner; [2020]
   Keywords : acoustophoresis; acoustofluidic; lab-on-a-chip; acoustic streaming; acoustic radiation force; particle trapping; particle washing; bulk acoustic waves; BAW; media exchange; cell manipulation;

   Abstract : In both, cell secretome analysis and bacteria evolution, controlled handling of particles with a few to sub-micrometers in size and media exchange are inevitable in order to investigate body fluid’s proteins or change the surrounding culture conditions for pivoted evolution. Typically, nanofiltration and ultra-centrifugation are employed which can lead to cell damage, need large sample volumes and have a high sample loss. READ MORE
