▎ 摘　　要

NOVELTY - The device (1) has collection module that is provided with an air extraction fan (11), an arc-shaped tapered air passage, a first pump, an oil-water container, and a second pump. A filter unit (10) is provided at the air inlet of the air extraction fan to preliminarily filter the air extracted and to generate impact force by the arc-shaped tapered airway to collect bioaerosols in the air to above the oil layer of the oil-water container. The detection module is provided with a sensing chip (14) unit, a signal processing unit, and a microcontroller (17) unit. A detection molecule is attached on the sensing chip unit to detect specific bioaerosols entering the biological buffer solution. The power supply supplies the power required by the collection module and the detection module. The nanomaterials are selected from magnetic nanobeads, gold nanoparticles, carbon tubes, graphene, and zinc oxide. The nanomaterials combined with thionine or Prussian blue. USE - Bioaerosol detection device for detecting biological aerosol such as viruses, germs, fungi, and pollen (all claimed). Uses include but are not limited to influenza, coronavirus such as severe acute respiratory syndrome, Middle East respiratory syndrome (MERS), COVID-19, chickenpox, Roolla rubeola, Norovirus, or calicivirus, and bacteria such as Mycobacterium tuberculosis, Bordetella pertussis, and methicillin-resistant Staphylococcus aureus. ADVANTAGE - The biological aerosol detecting device solves the problem of incompatibility of air sampling and sensing technology based on liquid. The biological buffer liquid under the oil layer is circulated through the sensing chip unit, to make the to-be-tested biological aerosols effective contact aptamer or antibody, capturing and detecting, and the capture and detection are achieved. The bio-aerosol to be tested in the biological buffer solution is designed by the circulating flow passage, matched with the drive of the second pump. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a bioaerosol detection method. DESCRIPTION OF DRAWING(S) - The drawing shows a functional block diagram of the bioaerosol detection module.
