Sensing of Airborne Nanoparticles Using Miniaturized Whipple Double Condenser

We have demonstrated the sensing of airborne nanoparticles using a miniaturized Whipple double condenser (MWDC). Each condenser (17 mm long, 2.2 mm wide, and 1 mm tall) was fabricated using photolithography and copper electroplating. The MWDC was theoretically shown to function within the laminar flow regime and capable of detecting 10and 20-nm particles at a flow rate of 0.3 LPM. Monodispersed is...
