Abstract: The present disclosure relates to a microbial concentration detection element in an unknown solution. In more detail, the microbial concentration detection element includes: a preprocessing unit configured to produce a microbe substitution solution by transferring microbes in an unknown solution containing detection target microbes into a reference solution through acoustophoresis, and to calculate electrical property information of the microbe substitution solution; and a microbe concentration measurement unit configured to separate the microbe substitution solution into a microbe concentration solution and a filtered solution through dielectrophoresis on the basis of the electrical property information measured by the preprocessing unit, and then measure a microbial concentration of the microbe concentration solution.

Abstract: The present invention relates to a blood diagnostic device, which includes one or more blood input parts into which blood is injected, a deterministic lateral displacement separation part which communicates with the blood input part to form a blood flow path along which the blood flows and separates white blood cells from remaining blood components, a first microchannel which communicates with the deterministic lateral displacement separation part so that the white blood cells separated through the deterministic lateral displacement separation part flow therein, one or more second microchannels which communicate with the deterministic lateral displacement separation part so that the remaining blood components separated through the deterministic lateral displacement separation part flow therein, a first discharge part which communicates with the first microchannel so that the white blood cells flowing in the first microchannel are discharged therethrough, and a second discharge part which communicates with the second microchannel.

Abstract: The present disclosure relates to a herringbone-type fluid guiding unit and an apparatus for concentrating fluid using same. The herring-bone type fluid guiding unit includes: a front member formed on a flow path and formed so that the width between the left side and the right side widens from a front end part toward the back, with respect to the flow direction of a fluid; and a rear member extending from the front member toward the back, wherein the rear member is provided with a recessed part that is recessed to a specific depth from the rear edge toward the front or with a protruding part that protrudes toward the back.

Abstract: The present invention relates to a multi-microorganism detection system, and more particularly, to a multi-microorganism detection system using a dielectrophoresis force. Provided is a rapid and accurate multi-microorganism detection system. Microorganisms are concentrated at a high throughput using DEP after synthesizing the microorganisms and fluorescent magnetic particles, and when a complex in which the fluorescent magnetic particles are bound to the microorganisms passes through a detection unit by moving only the microorganisms to the detection unit after separating the magnetic particles from the complex (i.e., the microorganisms to which the magnetic particles are bound) using a DEP force, a fluorescence signal of a specific wavelength band is generated according to the type of the fluorescent magnetic particle and the concentration of the microorganisms according to the type of microorganism is measured by measuring and analyzing the fluorescence signal.
