An airborne microbial measurement apparatus and a measurement method thereof are provided. An airborne microbial measurement apparatus according to an embodiment includes a discharge apparatus including a discharge electrode and a voltage supply unit applying a high voltage to the discharge electrode. A substrate is provided to a side of the discharge apparatus to collect an airborne microbe from air by a high voltage applied to the discharge electrode. A reagent injection apparatus supplies a dyeing reagent to the microbe collected on the substrate or a DNA of the microbe. A light emission measurement apparatus senses a quantity of light generated from the DNA to which the dyeing reagent is supplied. The discharge apparatus includes a controller controlling the voltage supply unit so that the voltage is applied to collect the airborne microbe or destroy an external wall of the collected airborne microbe.

Airborne microbial measurement apparatus and measurement method thereof

To provide a system by which evaluation of circumstances of contamination by microparticles having nucleic acid can be performed rapidly and accurately. The theme is achieved by a system for measuring microparticles that includes: (1) a microparticle adhesion step of adhering the microparticles having nucleic acid to a microparticle adhesion member; (2) a membrane breakage step of breaking membranes of the adhered microparticles by electrical discharge; (3) an electrophoresis step of electrophoresing the microparticles in a thickness direction of a gel to make the nucleic acid in the microparticles migrate from a negative electrode side toward a positive electrode side and adhere the nucleic acid on a surface of a nucleic acid detection member; and (4) a nucleic acid measurement step of fluorescently staining the surface of the nucleic acid detection member to measure a concentration of the nucleic acid.
