Figure 6.

Transmission electron microscope images of the blastoderm cells of affected embryos loaded with BSA-MWCNTs (MWCNTs-48 h) at 6 hpf. The membranes of the enveloping cells were disrupted (A and B).The deep-layer cells detached and had irregular nuclei with condensed chromatins (C).

Note: The white arrow points to corrupted membrane, and black arrow to irregular nucleus. Scale bar, 2 μm.

Abbreviations: BSA-MWCNT, bovine serum albumin-functionalized multiwalled carbon nanotube; hpf, hours postfertilization.
