Zeta potential of bare and capped silver nanoparticles
| Sample | Particle size (nm) | pH | Polydispersity index (PDI) | Zeta potential (mV) |
|---|---|---|---|---|
| Bare Ag nanoparticles | 69.2±5.0 | 4.30–4.37 | 0.235 | −38.5±11.5 |
| AgNpPGA | 44.9±5.0 | 0.206 | −43.7±12.0 |
Values are the mean ± standard deviation (n=5)
