TEM Core Diameter | TEM Shell Thickness | Size Distribution (CV) | Example Certificate of Analysis(How do I read this?) |
---|---|---|---|
50 nm ± 4 nm | 20 nm ± 5 nm | ≤ 15% | — |
70 nm ± 10 nm | 20 nm ± 5 nm | ≤ 15% | — |
100 nm ± 10 nm | 20 nm ± 5 nm | ≤ 15% | — |
Note: approximate ranges below are dependent on diameter
- Hydrodynamic diameter (DLS): TEM diameter plus 5 to 70 nm
- Zeta potential: –20 to –75 mV
- Particle surface: silanol
- Solvent: ethanol
- Peak wavelength (λmax): 440 to 540 nm
