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.
