Superoxide production was measured at DIV8 in SH-SY5Y cells exposed to PCL-NPs before (DIV1, NP DIFF) or during (DIV4, DIFF NP DIFF) differentiation with RA. Untreated controls, undifferentiated cells (CO UNDIFF) and differentiated cells (CO DIFF) were performed in parallel. Values are expressed as fluorescent intensity units (FIU)/mg protein; they are represented as percentage of undifferentiated control. Error bars represent the mean + SEM
