Methods and systems are provided for concentrating particles (eg, bacteria, viruses, cells, and nucleic acids) suspended in a liquid. The field-inducing force moves the particles towards the first electrode immersed in the liquid. When the particle is in close proximity (eg, in contact with) the first electrode, the electrode is withdrawn from the liquid, and the capillary force formed between the withdrawing electrode and the surface of the liquid fixes the particle on the electrode. When withdrawing the electrode from the liquid, the portion of the electrode pre-immersed in the liquid has particles fixed on the surface of the electrode. |
