Hello
Kindly help me to know the way to determine the stability of gold nanoparticles
Thanks

Refer to this table for comprehensive answer to your query:
| Method | Stability Marker | Best Used For |
|---|---|---|
| UV-Vis Spectroscopy | Peak at 520 nm | Quick assessment |
| DLS | Hydrodynamic size | Monitoring aggregation |
| Zeta Potential | Surface charge (>±30 mV) | Checking colloidal stability |
| TEM | Direct imaging | Morphology confirmation |
| Salt Test | Resistance to NaCl | Electrostatic stability |
| pH Test | Stability over pH 4–10 | Environmental resilience |
| Storage Test | Long-term consistency | Practical usability |
