Figure 4. Confocal pictures of macrophages treated with fluorescent nanoparticle (red), nuclei (blue), macrophages (white), merged (all).

Nanoparticles are seen in all sub cellular compartments confirming the multi targeted mechanism of gallium in macrophages. (A) Rab5 –early endosome, (B). Rab7- late endosome, (C). Rab11 – early recycling endosome, (D). Rab 14 – late recycling endosome. The control Ga-free nanoparticle showed very less nanoparticle in those compartments compared to Ga-NP.
