Abstract

Toward tracking lifelong exposure history of particulate matters (PMs) for understanding its disease risk, we realized a surfactant-assisted ionic current sensing for analyzing the size and concentration of hydrophobic PMs. Previously, we reported a PM sensor via water film-based collection and micropore-employed ionic current sensing at MicroTAS 2018 [1]. However, an analysis on PM number concentration has not achieved due to a difficulty in sensing hydrophobic PMs. Here, the hydrophobic PMs were detected with the aid of sodium dodecyl sulfate (SDS) and information on PM size and number concentration was obtained.
