A novel aerosol collection technique using suspended liquid films

A novel aerosol collection technique employing suspended liquid films has been investigated to advance current air sampling methods, which are crucial for detecting airborne particles, including pathogens. Electrostatic precipitation has recently emerged as a promising technique for efficiently capturing various airborne particles. Building on the principles of electrostatic precipitators, the developed method is designed to directly capture airborne material into a low volume suspended liquid film using electrostatic actuation. This approach is intended to increase collected particle concentration and minimise system losses, significantly enhancing both system sensitivity and limits of detection. Additionally, collecting particles into liquid is anticipated to help maintain the viability of collected biological materials.
