Fig. 2From: Quartz crystal microbalances (QCM) are suitable for real-time dosimetry in nanotoxicological studies using VITROCELL®Cloud cell exposure systemsTypical QCM signal (1 Hz) observed during aerosol-cell exposure with the VITROCELL® Cloud system (here: 200 μl fluorescein solution was nebulized according to recommended operating conditions in the Cloud 6). The following three phases can be distinguished: Phases I and II: nebulization and aerosol deposition phase with closed chamber, respectively; phase III: Complete drying of the sample with chamber open (top part removed)Back to article page
