Table 2.
The particle size results obtained by different methods. The relative standard deviations values shall be compared only within one sample type, since it is dependent on the particle size
| The size reported by manufacturer | Manual image analysis (D n) | Nanoannotator program (D n) | SAXS (D v) | |||
|---|---|---|---|---|---|---|
| Silver nanoparticles (diameter) | ||||||
| Average size | 40–55 nm [16] | 44.0 nm | 50.1 nm | 43.5 nm | ||
| Most frequent value | – | 42–44 nm | 42–44 nm | 35.0 nm | ||
| Relative standard deviation | – | 26.0 % | 30.2 % | 48.8 % | ||
| Iron oxide whiskers (length and width) | ||||||
| Average size | 40–150 nm [17] | 250–600 nm [17] | – | 127.5 nm | 939.0 nm | 40.9 nma |
| Most frequent value | – | – | – | 117–127 nm | 1050–1060 nm | 29.0 nma |
| Relative standard deviation | – | – | – | 41.1 % | 41.5 % | 54.0 %a |
