Table 3
Absorbance and wavelength deviation at different nanogold versus pH.
| | Nanogold/item | pH value | Absorbance | Wavelength (nm) |
| | Chem._nanogold | 3.1~11.5 | Increase | From 527 to 522 | | AuNPs-DIW | 2.5~10.8 | Increase | From 534 to 527 | | Ethanol nanogold | 7.1~11.5 | Increase | From 544 to 534 | Ethanol nanogold
(1/2 ethanol + 1/2 DIW) | 3.1~10.5 | No change | From 540 to 520 |
