Primary biological aerosols play a crucial role in the Earth system. In particular, in interactions between the atmosphere, biosphere, climate and public health. Field measurements of bioaerosols have been carried out in a variety of basic and applied scientific disciplines. Atmospheric science alone constitutes a large sum of research topics with open questions related to cloud formation, climate, hydrological cycles and many more.

Our main topics:

• Field measurement

Challenges for science

Broadly speaking, scientists and researchers are working on the three overarching themes of climate change, land use change and public health. In most cases, we are concerned with finding the source and understanding how bioaerosols spread.

Climate Changes

Field measurement in bioaerosol research

For the field measurement of bioaerosols, Swisens provides new technologies that can measure morphological and chemical properties of bioaerosols. Modern measuring instruments are mostly automated and allow continuous monitoring, so that a large number of particles can be measured. This produces large amounts of data. The identification and categorisation of the measured particles with conventional methods are unsatisfactory so far and mean a high effort for the evaluation. Therefore, the timely observation of dynamic processes is not possible and large gaps in understanding remain.

Learn more about our technology and measurement systems for bioaerosol research.

The requirements for field measurements in bioaerosol research are thus as follows:
  • comprehensive particle characterisation
  • real-time measurement
  • open data access to measurement data
  • Artificial Intelligence for the identification of bioaerosols
  • extension of the integrated algorithms
  • comprehensive software for efficient data analysis
  • integrated data management for processing BigData
  • fully automatic operation and low maintenance
  • robust construction for tough conditions in the field

The solution is therefore not a single instrument that can measure bioaerosol particles, but a system of seamlessly integrated components to accelerate and advance bioaerosol research.

SwisensEcosystem Bioaerosol Research

Swisens has recognised that a single measurement instrument can only provide limited support for bioaerosol research. Therefore, we offer a unique ecosystem of hardware, software and service components and enter into open scientific collaborations.

We provide tools, services and support in the use of the latest technologies and contribute to the further exploration of the microcosm of aerosol particles.

“Swisens has shown to be a service-oriented partner in any case, addressing requests diligently. Our suggestions have always been heard and have been systematically translated in technical improvements. In short, Swisens AG has shown to be strongly oriented towards client and market needs. Finally, the tests we performed with Swisens AG resulted in a fruitful scientific exchange. In all, it is for us a great pleasure to recommend Swisens AG for operational or research projects in the field of automatic pollen measurements.”

University of Manchester

“I speak on behalf of my colleagues who are Urban Observatory Principal Investigators and Research Collaborators from the University of Manchester that we have rarely seen, or been provided with such exemplary support as that provided by Swisens. Swisens customer support has been remarkable given the current situation, from remote training and commissioning to rapid support for hardware and software tools specific to our needs to extremely well organised seminars that actually focus on customer feedback and needs. In particular we have been impressed with the Swisens open source data approach and their attention to different users specific needs. Swisens technical innovations has already generated enormous interest in a bioaerosol-aerobiology community that until recently has been limited with respect to real-world and near real-time detection and importantly quantification of airborne bioaerosol concentrations. Their approach has developed significant rapport with multi-disciplinary researchers and Swisens should be lauded for this.”

Mikhail Sofiev –
Research Professor
Atmospheric Composition Research Department
Finnish Meteorological Institute

“The Finnish Meteorological Institute is very satisfied with the cooperation of Swisens AG. The agreed research and development programme is progressing well and mutual openness and collaborative atmosphere strongly supports it. Swisens participated in a workshop and supported the scientists in recording the test data based on the cooperation agreement. A particular outcome of the workshop was a new procedure for the calibration of real-time monitoring systems based on the SwisensAtomizer. It has been proven to deliver cleaner results than the approaches tried so far in different countries. FMI is very satisfied with cooperation of Swisens AG. Our suggestions regarding software tools were quickly accepted and implemented by Swisens engineers. We are indeed happy to work with Swisens and start opening real-time data to professionals in Finland.”

“Being able to aerosolize different powder samples in the lab to perform experiments related to occupational health has been one of our challenges. With the SwisensAtomizer at hand, we now have a small device which helps us to produce a stable dust atmosphere to load filters in a consistent manner, serving as calibration filters for later analysis. Swisens AG has always shown great support concerning our demands on the SwisensAtomizer. We are delighted to collaborate with Swisens AG.”
