Interaction of BHK cells with PMMA–PTE
nanoparticles at
a concentration of 25 ppm. The images represent the nucleus stained
with DAPI (A), cellular matrix stained with nanoparticles (B), and
an overlay of the two images (C), with the magnified images in the
inset showing nanoparticle distribution inside the cells (D). Magnified
view (D) of nucleus stained with DAPI (i), cellular matrix stained
with nanoparticles (ii), cells observed under DIC mode (iii), and
overlay of (i)–(iv). The cells were imaged at a magnification
of 60× oil objective using a confocal microscope (Olympus FV1000).
