Fig. 8. Time-gated luminescence images of Daphnia magna treated with the RTLNP (100 μg ml–1) for 1.5 h (a), and followed by incubation with HClO (50 μM) for 20 min (b) (1: the images at the red channel; 2: the images at the green channel; 3: overlap of luminescence and bright-field images; 4: I green/I red ratiometric images). Scale bar: 200 μm.
