Overview and perspectives in real-time measurement of bioaerosols

The detection of bioaerosols or primary biological aerosol particles (PBAPs) has become increasingly important for a variety of research communities and scientific questions. In particular, in the fields of environmental science, allergy monitoring, agriculture, public health and national security. In particular, real-time measurement (link) technologies for autonomous online detection and characterisation of PBAP properties in outdoor and indoor environments are becoming increasingly common and have opened up new research opportunities. However, with technological advances comes the challenge of standardising procedures so that results are both reliable and comparable across technologies and users. This publication provides a critical overview of the major classes of instruments used in bioaerosol research. Eight main classes of real-time technologies are covered, including the following: (i) fluorescence spectroscopy, (ii) elastic scattering, microscopy and holography, (iii) Raman spectroscopy, (iv) mass spectrometry, (v) breakdown spectroscopy, (vi) remote sensing, (vii) microfluidic techniques and (viii) paired aqueous techniques.

This publication provides a detailed overview of the technology for real-time measurement of bioaerosols. Included is our technology and SwisensPoleno Jupiter for fully automatic, real-time measurement of bioaerosols.
