| Zusammenfassung |
| The interest in bioaerosols has traditionally been linked to health hazards
for humans, animals and plants. However, several components of bioaerosols
exhibit physical properties of great significance for cloud processes, such
as ice nucleation and cloud condensation. To gain a better understanding of
their influence on climate, it is therefore important to determine the
composition, concentration, seasonal fluctuation, regional diversity and
evolution of bioaerosols. In this paper, we will review briefly the existing
techniques for detection, quantification, physical and chemical analysis of
biological particles, attempting to bridge physical, chemical and biological
methods for analysis of biological particles and integrate them with aerosol
sampling techniques. We will also explore some emerging spectroscopy
techniques for bulk and single-particle analysis that have potential for
in-situ physical and chemical analysis. Lastly, we will outline open
questions and further desired capabilities (e.g., in-situ, sensitive, both
broad and selective, on-line, time-resolved, rapid, versatile,
cost-effective techniques) required prior to comprehensive understanding of
chemical and physical characterization of bioaerosols. |
