Abstract

The invention discloses a single bioaerosol particle identification system based on laser capture and microwave radiation. A laser tweezer is used for fixing and applying directional microwave radiation to distinguish biological and non-biological particles in the atmosphere; meanwhile, a digital camera is combined to record the change of fixed states of the particulate matters to identify singlebioaerosol particles, thus realizing single capturing, fixing, screening and subsequent recording and analysis of biological and non-biological aerosol particles; and the system can be widely appliedto in-situ detection of atmospheric particulates contained in indoor and outdoor environment air, especially in-situ screening and recording of biological particles and non-biological particles in theatmospheric particulates.

Description

technical field [0001] The present invention relates to biological aerosol identification technology, in particular to a technology that uses laser optical tweezers to fix and apply directional microwave radiation to distinguish biological and non-biological particles, and at the same time combines digital cameras to record changes in the fixed state of particles to identify single biological aerosol particles The identification system realizes single capture and fixed screening of biological and non-biological aerosol particles and subsequent record analysis, which can be widely used in the in-situ detection of atmospheric particles contained in indoor and outdoor ambient air, especially the in-situ identification of microbial particles and abiotic particles and record. Background technique [0002] Air pollution has become an environmental issue of widespread concern to society, especially microbial aerosols have a direct and significant impact on human health. Exposure t...
