摘要： Disclosed is an apparatus for monitoring bioaerosols, including a capturer configured to capture bioaerosol particles in air in a capture solution; a particle sprayer configured to electro-spray the capture solution in a form of droplets such that the particles are included in at least some of the sprayed droplets; and an analyzer configured to analyze the particles, sprayed through the particle sprayer, by machine learning. In accordance with such a configuration, the droplets containing a certain amount of the particles can be continuously analyzed in real time by machine learning, thereby contributing to the improvement of monitoring efficiency for a specific bioaerosol genus.

摘要： Disclosed is an apparatus for capturing bioaerosols. More particularly, the apparatus for capturing bioaerosols includes a sprayer configured to spray a buffer solution for protecting aerosol particles in a form of droplets; and a capturer into which air including the droplets and the aerosol particles is introduced and in a capture solution in which the aerosol particles are captured, wherein discharge members provided with a plurality of nanostructures are provided on a surface of the capturer to charge the aerosol particles. Due to such a configuration, high discharge efficiency can be anticipated even at a low voltage without damage to aerosol particles.

摘要： The present invention relates to an apparatus for real-time continuous measurement of airborne microorganisms including a body unit, a vaporization unit, a liquefaction unit, a coating unit, and a measurement unit. The body unit has an inlet through which airborne microorganisms are introduced and an outlet through which airborne microorganisms are discharged. The vaporization unit vaporizes a lysis solution and supplies the vaporized lysis solution to the inside of the body unit. The liquefaction unit cools the vaporized lysis solution to condense the vaporized lysis solution on the surfaces of the airborne microorganisms. The coating unit applies a light-emitting agent onto the airborne microorganisms lysed by the lysis solution. The measurement unit detects the intensity of light generated by reacting the airborne microorganisms and the light-emitting agent and measures the concentration of the airborne microorganisms.
