Au Nanobipyramids, NBP-45-850-50 (CAT#: STEM-NB-0008-LC)

NanoSeedz™ provides gold nanobipyramid products in high purity and high monodispersity. The number percentages of gold nanobipyramids in the products are >95%. The ensemble longitudinal plasmon peak widths are nearly equal to the corresponding single-particle values, suggesting that inhomogeneous peak broadening is eliminated. Moreover, gold nanobipyramids exhibit larger electric field enhancements than gold nanorods. Their refractive index sensitivities and figure-of-merit values are both much larger than those of gold nanorods on the market. Such high-quality gold nanobipyramids are expected to bring tremendous performance improvements in various plasmonic applications, such as high-density optical data storage and high-performance chemical and biological sensing.
