Abstract

In this paper, an efficient electrostatic particle
sampling system is developed based on the neutralized ion
wind. Compare with the conventional schemes where
unipolar ion is used to charge the airborne sample and the
sampling stage is fixed as a part of high voltage circuit, the new approach allows sampling stage to be electrically
floated and adds insignificant charge to the bioaerosol, thus reduces damages to the microorganisms while provides
design flexibility and good collecting efficiency. The
approach is suitable for the combination with a microfluidic interface to develop complex aerosol-tohydrosol
bio-samplers.
