Fig. 8From: Preliminary Studies on Biodegradable Zinc Oxide Nanoparticles Doped with Fe as a Potential Form of Iron Delivery to the Living OrganismDistribution of iron within analyzed tissues 24 h following IG administration of ZnO:Fe NPs. Data represents an average percentage of Fe in tested organs from experimental group (n = 4) compared with the control group (100%—horizontal line). Iron content was analyzed with AAS.
