Acoustophoresis separation of bacteria from blood cells for rapid sepsis diagnostics

Ohlsson, P. D. LU orcid ; Petersson, K. LU ; Augustsson, P. LU and Laurell, T. LU (2013) 17th International Conference on Miniaturized Systems for Chemistry and Life Sciences, MicroTAS 2013 2. p.1320-1322
Abstract

We present a significantly improved acoustophoresis method to separate bacteria from red and white blood cells. As much as 98% of the bacteria were recovered, while only 0.06 % of the red and white blood cells remained. This 1600-fold relative enrichment was achieved by adjusting the center medium density, tightly controlling the chip temperature and stabilizing the fluid flows. This is a crucial sample preparation step facilitating downstream bacteria identification for sepsis diagnostics.
