Gold Nanoparticles Custom Designed as Improved Labels for Lateral Flow Assays:
| Diameter | CV | SPR Peak | 80% SPR Peak Width | Zeta Potential | pH | Surface | Example TEM | Absorption Spectra |
| 40nm | ≤10% | 523.5 ± 1.0nm | ≤37nm | -45 ± 15mV | 7-8.5 | Citrate |  |
 |
| 60nm | ≤8% | 533.5 ± 2.0nm | ≤41nm | -45 ± 15mV | 7-8.5 | Citrate |  |

With an optimal combination of cherry red contrast and surface area to minimize wasted targeting biomolecules, 40 nm diameter gold nanospheres are the most popular choice for lateral flow assays. 60 nm Gold NanoSpheres produce a lighter red contrast, but the optical absorbance per nanoparticle is greater. Thus, fewer particles are needed to produce a measurable reading; an advantage for low target analyte concentration samples, or when using expensive targeting moieties.
