    • A virus in the atmosphere can be precisely detected on a real time basis. At a main pipeline 8, a dust removing unit 1, an atomization unit 4, a fluorescence measuring unit 5 in which a laser beam is irradiated, and a suction pump 7 are arranged in this order, and a suctioned air current is generated in the main pipeline 8 through the suction pump 7. Meanwhile, a diffusion unit 3 includes a liquid flow path 35 and a gas flow path 34 formed in parallel to the liquid flow path, and an atmosphere and an aqueous solution containing a fluorescent antibody F pass through the gas flow path 34 and the liquid flow path 35, respectively. The aqueous solution is flown into the atomization unit 4 through a guide passage 40 branched from a branch part that is formed at an outlet side of the flow paths 34 and 35 and discharges the gas and the aqueous solution after separating the gas and the aqueous solution. A mist group is flown into the fluorescence measuring unit 5. Since a fluorescence intensity of the mist M when the virus V exists is higher than a fluorescence intensity when no virus V exists, the virus V can be detected by monitoring the fluorescence intensity.
    • 可以在实时的基础上精确检测大气中的病毒。 在主管8处,依次布置有除尘单元1,雾化单元4,照射激光的荧光测量单元5和抽吸泵7,并且在该管道8中产生吸入的气流 主管道8通过抽吸泵7.同时,扩散单元3包括液体流动通道35和与液体流动通道平行形成的气体流路34,并且含有荧光抗体F的气氛和水溶液通过 气体流路34和液体流路35。 水溶液通过从形成在流路34,35的出口侧的分支部分分支的引导通道40流入雾化单元4,并在气体和水溶液分离后排出气体和水溶液 。 雾组被流入荧光测定单元5.由于存在病毒V时的雾M的荧光强度高于不存在病毒V时的荧光强度,因此可以通过监视荧光强度来检测病毒V.
