Figure 3From: Intrinsically superparamagnetic Fe-hydroxyapatite nanoparticles positively influence osteoblast-like cell behaviourCell proliferation assay. The Picogreen DNA content assay was performed on cultures of osteoblast-like cells seeded with 4 different concentrations of HA and FeHA nanoparticles at 1, 3 and 7 days of culture (n = 5). n.s. = not significant; *** p≤0.001.Back to article page
