TL;DR: It was demonstrated that this method utilizing airborne silver nanoparticles offers potential as a bioaerosol control methodology.
Abstract: In the present study, a control methodology utilizing airborne silver nanoparticles is suggested and tested with respect to its potential to control Gram-positive Staphylococcus epidermidis and Bacillus subtilis, and Gram-negative Escherichia coli bacteria bioaerosols deposited on filters. As it is known that the Gram-negative bacteria are sensitive to airflow exposure, the main focus of this study for testing the airborne silver nanoparticles effect was the Gram-positive Staphylococcus epidermidis and Bacillus subtilis bacteria bioaerosols whereas Escherichia coli bioaerosols were utilized for comparison. Airborne bacteria and airborne silver nanoparticles were quantitatively generated in an experimental system. Bioaerosols deposited on the filter were exposed to airborne silver nanoparticles. The physical and biological properties of the airborne bacteria and airborne silver nanoparticles were measured via aerosol measurement devices. From the experimental results, it was demonstrated that this method utilizing airborne silver nanoparticles offers potential as a bioaerosol control methodology.

TL;DR: In this paper, a comparative performance of two common biosamplers, including the single-stage Andersen impactor and the all-glass impinger (AGI) for bioaerosol sampling, was also evaluated.
Abstract: Indoor bioaerosols have recently received considerable interest because of their impact on health. In this study, concentrations of bioaerosols in relation to airborne particulate matter in various indoor environments were investigated. The comparative performance of two common biosamplers, including the single-stage Andersen impactor and the all-glass impinger (AGI) for bioaerosol sampling, was also evaluated. The average levels of airborne bacteria and fungi sampled by Andersen were 516 and 176 colony forming units (CFU) m–3 and by AGI were 163 and 151 CFU m–3, respectively. The highest bacterial levels were measured in residence apartments. The most predominant bacteria were belonged to Staphylococcus sp. and Arthrobacter sp. The Andersen impactor appeared to yield fungal concentrations that were comparable to the results obtained using the AGI biosampler. Meanwhile, Andersen impactor counts for bacteria were significantly higher than those obtained by AGI. Particle count data generated by the optical particle counter indicated that 95% of airborne particles were < 1 µm in diameter. Statistical analysis revealed a significant correlation between particle counts of PM1 and concentrations of culturable airborne bacteria measured with the both bioaerosol samplers.
Based on these results, the Andersen impactor performed much better than the AGI for sampling airborne bioaerosols in low-contaminated indoor environments. Accurate measurement of microbial concentrations in indoor environments should be performed by bioaerosol monitoring; however, combining particle counting with bioaerosol sampling could provide prompt information about rapid variations of air quality.
