Measurement of intracellular Ca2+ concentration after stimulation by different ENPs. Different phytoplankton cells a Dunaliella tertiolecta, b Thalassiosira pseudonana, c Skeletonema grathae, d Phaeodactylum tricornutum, and e Odontella mobiliensis were treated with TiO2 25 nm (green), SiO2 10–20 nm (red), CeO2 15–30 nm (purple) with a concentration of 1 mg/ml and control (blue). Black arrow indicates the time point when EPNs were applied (30 s). The measurements show representative data from an average of 20 individual cells
