Reaction conditions of biosynthesis of silver nanoparticles (b-AgNPs) using Olax Scandens leaf extract.
| Exp. No | OX-Extract (μL) | AgNO3 (μL) | Water (mL) | *Time (hour) | Size from DLS (nm) | Size from TEM (nm) | Zeta potential (charge mV) |
|---|---|---|---|---|---|---|---|
| 1. | 150 | 150 | 4.70 | ~ 7 | ~ 85-130 | 20-110 | - 11.8±0.2 |
| 2. | 400 | 150 | 4.45 | ~4.5 | ~ 75-140 | 10-85 | - 10.1±0.7 |
| 3. | 500 | 150 | 4.35 | ~ 2 | ~ 55-100 | 10-55 | - 15.2±0.5 |
| 4. | 750 | 150 | 4.10 | ~1.5 | ~ 60-140 | 10-90 | - 13.2±0.4 |
[a] *Time was required to appear the yellow coloration. Total volume of reaction mixture was maintained at 5 mL (formation of b-AgNPs).
