The OECT real-time monitoring of HRT-18 cell growth infected with B-CoV in suspension (a) and adhesion (b) for 48 h. Each OECT time response point is the average of five consecutive measurements, having the standard deviation reported as the curve shadow. The normalized Incucyte^® data of HRT-18 cell growth, infected with B-CoV in suspension (c) and adhesion ((d), the data were taken and normalized after viral incubation). The experiments were stopped 72 h post virus infection, except for the Incucyte screening in adhesion, which was stopped after 48 h since a clear cytopathic effect had already been monitored by the OECTs.
