ABSTRACT:
A method and apparatus for evaluating a bioaerosol sample is provided which includes detecting frequency and/or time resolution factors that allow discriminate between a plurality of signals emitted by the bioaerosol to selectively detect biological materials contained in the bioaerosol sample from materials of non-biological origin and potentially associated with a pathogenic bioaerosol.
