Notes: *Concentrations measured by ICP-MS analysis (1/10 of Stock solution B). **Concentrations (μM) of metals in larger molecular weight fraction (calibrated by FH) ***Concentrations (μM & %) of metals retained by FHNPs. ****Percentage (%) of doped metals at 120°C vs RT (Column 4 vs Column 3) by a one-tailed Welch’s T-test. Significance (ǂ) was determined with FDR controls (α=0.05).
