Abstract
Environmental air monitoring is of great interest due to the large number of people concerned and
exposed to different possible risks. From the most common particles in our environment (e.g. byproducts
of combustion or pollens) to more specific and dangerous agents (e.g. pathogenic microorganisms),
there are a large range of particles that need to be controlled. In this article we propose an
original study on the collection of electrostatically deposited particles using electrowetting droplet
displacement. A variety of particles were studied, from synthetic particles (e.g. Polystyrene Latex (PSL)
microsphere) to different classes of biological particle (proteins, bacterial spores and a viral simulant).
Furthermore, we have compared ElectroWetting-On-Dielectric (EWOD) collecting efficiency using
either a hydrophobic or a superhydrophobic counter electrode. We observe different cleaning
efficiencies, depending on the hydrophobicity of the substrate (varying from 45% to 99%).
Superhydrophobic surfaces show the best cleaning efficiency with water droplets for all investigated
particles (MS2 bacteriophage, BG (Bacillus atrophaeus) spores, OA (ovalbumin) proteins, and PSL).
