Abstract

Toward evaluating health risk of particulate matter with size less than or equal to 2.5 μm (PM2.5), we propose a methodology for realizing the PM2.5 analysis in liquid phase via water film-based collection and microfluidics-based electrical detection. We reported last year that a hydrophilic nanowire surface was utilized in the collection for formation of a water film, which enabled continuous collection of air-floating PM2.5 into liquid phase and followed-by detection. As advanced results, the collected PM2.5 was successfully detected and analyzed via ion current sensing using a micropore. We believe proposed PM2.5 analysis methodology in liquid phase would allow to realize health risk evaluation and reduce health damage.
