Abstract:
1. A method for at least one of separating and accumulating polarizable bioparticles, the method comprising: using a microfluidic cell, including: performing an accumulation phase, wherein a high-frequency alternating voltage is applied to the electrodes of the interdigital electrode system during the accumulation phase calming a flow of bioparticles in a region of the interdigital electrode system using the micromixer; inhibiting a washing out of the bioparticles in the region of the interdigital electrode system using the micromixer; and performing at least one of the following: (i) a lysis phase, wherein a low-frequency alternating voltage is applied to the interdigital electrodes, and (ii) a removal phase, wherein a low-frequency or square wave voltage is applied between the interdigital electrode system and the flat electrode; wherein the lysis phase and the removal phase are performed simultaneously by applying the low-frequency alternating voltage.
