Kelvin Probe Force Microscopyを用いたエアロゾル個別粒子の帯電状態の測定
Measurement of the Electrostatic Charging State of Individual Particles in Ambient Aerosol Using Kelvin Probe Force Microscopy (Okuda, Gunji, Lenggoro)
Recently, the importance of electrostatic charging state to particle deposition in the human airways has been suggested. We developed a measurement method of electrostatic charging state of individual ambient aerosol particles using Kelvin probe force microscopy (KPFM). For the ambient aerosol particles, the surface potential ranged from－56.6 mV to＋156.7 mV, indicating that the number of elementary charges of ambient aerosol particles analyzed in this study was more than 4.
