    Abstract
    In bioaerosol monitoring applications, technologies allowing rapid and precise detection of airborne pathogens are highly demanded. One of such technologies, based on the immunoreaction-operating principle in nearly real-time mode without any specific labeling, is known as surface plasmon resonance (SPR). In previous studies, we have shown applicability of the SPR technology for rapid and selective detection of viral and bacterial aerosols where successful combination of the SPR machine with our earlier produced personal bioaerosol sampler opened new prospects in development of portable bioaerosol monitors. The current study ...

    In bioaerosol monitoring applications, technologies allowing rapid and precise detection of airborne pathogens are highly demanded. One of such technologies, based on the immunoreaction-operating principle in nearly real-time mode without any specific labeling, is known as surface plasmon resonance (SPR). In previous studies, we have shown applicability of the SPR technology for rapid and selective detection of viral and bacterial aerosols where successful combination of the SPR machine with our earlier produced personal bioaerosol sampler opened new prospects in development of portable bioaerosol monitors. The current study is a logical continuation of our previous research dedicated to the technology development for rapid bioaerosol detection. Here, we focus on one of the main factors possibly influencing the SPR-based bioaerosol monitoring; the SPR performance on target bioaerosol detection was evaluated at conditions of substantial air contamination with different nontargeted microorganisms, commonly presented in the air. Besides, different compositions of sampling liquids were tested in regards to the SPR results interference. Our findings clearly verified high specificity of the technology even in cases of highly contaminated air environments with aerosols of biological and mineral origins. It was found that both nontargeted bioaerosols and nanosized aerosols of mineral background do not have significant influence on the specific SPR detection of targeted bioaerosols.
