Description
Nanoscientifica Gold Single-Crystal Particles covers a wide range of monodisperse, monocrystalline gold nanoparticles with a quasi-spherical shape with a low population of polycrystalline nanoparticles (<10%). Colloidal suspension of gold spherical nanoparticles shows strong light absorption in the visible region due to the intense surface plasmon resonance cross-section. NanoScientifica Gold Single-Crystal Particles are manufactured with cutting-edge technology, free from aggregation, ready to straighten their full performance in your research, development, and use in industrial-scale in your demanding applications. Our nanoparticles are precisely characterized using UV/VIS spectrophotometry, Transmission Electron Microscopy (TEM), dynamic light scattering (DLS, particle size analysis) and/or Zeta potential (surface charge) measurements.
Special features
Due to the high crystallinity, NanoScientifica Gold Single-Crystal Particles are ideal building blocks to the fabrication of multimetallic core-shell nanostructures by epitaxial overgrowth, whether to generate polycrystalline or monocrystalline shell surfaces. Due to the narrow size distribution of our nanoparticles, the sharp localized plasmon resonance peak (LSPR) enables the fabrication of ultrasensitive optical sensors and it is the most recommended product for experimental-theoretical academic works.
