(a) Schematic of the experiment setup. (b) Representative picture of the blocking device at an 8 cm height using steel wool as the collecting electrode. (c) Mist flow without negative ions and an electric field. (d) Mist flow with negative ions and an electric field using steel wool as the collecting electrode. (e) Mist flow with negative ions and an electric field using agarose as the collecting electrode. (f) Relationship between the fluorescent dye concentration and device-height. “Agarose” indicates the device with negative ions and an electric field using agarose as the collecting electrode. “Steel wool” indicates the device with negative ions and an electric field using steel wool as the collecting electrode. “Without NI and EF” indicates the device without negative ions and an electric field. The error bars indicate the deviations of the three experiments. (g) Relationship between the blocking ratio and device-height.
