Microscopy images of CNT after RAW 264.7 macrophages exposure for 48 h. Panel a TEM images of S-, SF-, L- and LF-CNT recovered in RAW 264.7 cells exposed for 48 h to the different CNT. Panel b Optical microscopy images of S-, SF-, L- and LF-CNT recovered in RAW 264.7 cells exposed for 48 h to the different CNT. Panel c Length of S-, SF-, L-, and LF-CNT recovered from the cellular (Cell) or supernatant (SN) fractions of 48 h-exposed RAW 264.7. Abbreviations as in Fig. 1. Data are given as mean ± SEM
