An abundance of effective technologies exist for the point detection of biological aerosols, but their effectiveness is only as good as the front-end aerosol sampling method. Traditional inertial aerosol concentrators are currently used to sample the and concentrate aerosols to increase the sensitivity of point detectors. But, inertial concentrators require power-hungry blower fans, they tend to clog, and they are only effective on larger particles (e.g., 2 micron and larger)
