Determination of carbon particle background during placental perfusion with plain perfusion medium. Placental perfusion is performed for 6 h with empty PM, and the carbon particle content is determined using femtosecond pulsed laser illumination in PM before perfusion (a) as well as in the maternal and fetal perfusates over time (b). Data represent the mean (SD) of three technical replicates (a) and two independently perfused placentae (b). p < 0.05 is considered statistically significant (* denotes differences in carbon particle concentration determined in fetal perfusates over time compared to the initial amount) as analyzed by one-way ANOVA with Tukey’s multiple comparison correction. ANOVA analysis of variance, PM perfusion medium, SD standard deviation
