Particle size distribution and zetapotential
| highest peak size ± sd | mean size ± sd | zetapotential (mV) ± sd | |
|---|---|---|---|
| 50 nm gold single | 54 ± 3 | 61 ± 3 | -56 ± 0,42 |
| 50 nm gold agg | 114 ± 73 | 199 ± 88 | -54 ± 1,01 |
| 250 nm gold single | 197.5 ± 7 | 197 ± 12 | -53 ± 0,53 |
| 250 nm gold agg | 762 ± 762 | 768 ± 766 | -61 ± 0,98 |
Highest peak size and mean particle size in this distribution is determined by tracking analysis of Brownian motion. Zetapotential is determined by using the Zetasizer instrument.
