The present invention discloses a pathogenic microorganisms rapid concentration device and method. The device comprises an electrode and a microchannel for passing a sample, wherein the microchannel comprises a concentration channel and a sample channel, between which a filter element is provided, the electrode comprises a positive electrode and a negative electrode, the positive electrode comprises several sub-positive electrodes, after the sample flows into the microchannel, under the action of the electrode, pathogenic microorganisms in the sample are regionally enriched on a positive electrode side of the concentration channel to form a concentrated sample. The present invention provides a substantial increase in the rate and efficiency of purification of samples containing pathogenic microorganisms through precise electrical control. The concentration of pathogenic microorganisms can be achieved accurately and efficiently by controlling the voltage applied by the sub-positive electrode, which provides a good basis for the integration, automation, rapid and continuous sampling, and detection.
A pathogenic microorganisms rapid concentration device, comprising an electrode and a microchannel for passing a sample, wherein the microchannel comprises a concentration channel and a sample channel, between which a filter element is provided, the electrode comprises a positive electrode and a negative electrode, the positive electrode comprises a plurality of sub-positive electrodes provided in a spaced array on a side close to the concentration channel, the negative electrode is provided on a side close to the sample channel, wherein when a fluctuating voltage greater than zero is applied to one of the plurality of sub-positive electrodes, the voltage of another of the plurality of sub-positive electrodes adjacent to the one of the plurality of sub-positive electrodes alternates with the fluctuating voltage to form a varying potential difference between the one and the another of the plurality of sub-positive electrodes to regionally enrich pathogenic microorganisms in the sample flowing into the microchannel on a positive electrode side of the concentration channel to form one or more enrichment regions with the pathogenic microorganisms in the concentration channel.
