(a) Confocal, (b) composite and (c) bright field images showing the localization patterns of the PMNC in live THP-1 macrophage cells following a 24 hour co-incubation period. Panel (a) shows the clear fluorescence labelling of the outer cell membranes by the nanoparticles. The PMNC did not penetrate the cell membrane as these cells were not incubated with serum free media.
