Abstract

We have demonstrated a PM 2.5 analysis method that adds information on the number concentration and size by using microfluidic-based ionic current sensing with a bridge circuit. The bridge circuit allows for suppression of the background current and the detection of small PM 2.5 particles, even if a relatively large micropore is used. This is the first demonstration of the detection of PM 2.5 particles via ionic current sensing; our method enables analyses of both the number concentration and size.
