From: Shape dependent cytotoxicity of PLGA-PEG nanoparticles on human cells
Needle-shaped PLGA-PEG NPs induced DNA fragmentation by TUNEL assay. Confocal images (merged with transmitted channel) of HepG2 cells (stained with TUNEL Red) after their being fed with (a) & (b) none, (negative and positive control), (c) spherical- and (d) needle-shaped NPs at 250 µg/mL for 24 hours. (Red: TUNEL. All the figures share the same scale bar).
