    Abstract

    Airborne non-gas phase nanoparticles have been successfully collected using a relatively low power (approximately 200mW at 80μA) and small footprint (approximately 1cm2) microfabricated electrostatic precipitator. Polydispersed liquid phase oleic acid nanoparticles with size distribution of 30nm to 300nm are electrically charged and precipitated from the carrier gas phase medium at atmospheric pressure and temperature. The change in resistivity between the electrodes resulting from the build-up of precipitating nanoparticles is experimentally measured. Experimental airborne particles flux to the collection grid due to precipitation is approximately 4×10 4 particles per second for a concentration of approximately 1.5×106 particles per cubic centimeter.
