摘要：
Embodiments of an apparatus for concentrating and collecting airborne particles (e.g., biological aerosols) from an air sample include an inlet adapted for receiving the air sample (e.g., from an external or surrounding environment), a first diffuser coupled to the inlet and adapted to concentrate the airborne particles into a particle flow, and at least a second diffuser coupled to the first diffuser in a cascaded configuration and adapted to further concentrate the particle flow.
