Saturation magnetic moments of microdisk suspensions (samples h, i and j) at RT dried directly on a quartz holder, volume taken from each suspension, microdisk concentration in the aqueous suspensions determined by hemocytometer, the macroscopic estimation of NPs/μm2 and the corresponding NPs/μm2 value from SEM characterization.

The error of the macroscopic estimation has been determined from the counting by the hemocytometer.

**

The error in the SEM estimation corresponds to the analysis of 5 different areas.
