I Confocal laser scanning microscopy (CLSM) images of the ECCNBs (a–c) on SGC-7901 cells at the predetermined point of 1, 2, and 4 h, respectively. In each case, 1, 2, and 3 indicate DAPI, FITC, and Merge, respectively. II SGC-7901 cells were treated with 30 μg/mL etoposide in two forms of ECCNBs (e2–e4) and void etoposide (d2–d4). As the plots show, the number of events (y-axis) with high fluorescence intensity (x-axis) increases by 4 h incubation with ECCNBs but without any evident change for void etoposide. Negative control (d1, e1) includes non-treated cells to set their auto-fluorescence as “0” value
