Silver Nanocubes

NanoSeedz™ provides high-quality silver nanocubes. Their specifications are given below. The number purities of the silver nanocubes are >95%. The nanocube samples are characterized and examined by extinction spectroscopy and electron microscopy before delivery. We try our best to maintain the size, shape uniformity and number purity of the silver nanocubes. However, slight variations in size are unavoidable due to fluctuations during synthesis.

Average edge length: 73.0 ± 3.2 nm and 101.5 ± 5.3 nm

Mass concentration: 0.05 mg/mL

Surface capping agent: poly(vinylpyrrolidone) (PVP, molecular weight: 55,000)

Dispersing solvent: ethanol (PVP, 0.2 mg/mL) + H2O at 1:1 v/v

Hydrodynamic diameter: ~130 nm and ~180 nm

Surface Zeta potential: ~25 mV

The silver nanocubes are provided as follows.

Edge length (nm) Quantity (bottles) Absolute amount of silver (mg) Price (US$)
73.0 1 0.5 100
10 5 900
20 10 1600
101.5 1 0.5 100
10 5 900
20 10 1600

The silver nanocubes are suggested to be kept in solution and stored at 4 °C in a refrigerator without exposure to light. To ensure good dispersion of the silver nanocubes in solution before use, please EITHER perform sonication for 1 minute followed by quick vortex, OR manually shake to ensure that the sediment is evenly dispersed.
