    Description
    Nanoscientifica Gold Particles endows a series of monodisperse polycrystalline nanocrystals with a spherical shape with an average diameter ranging from 10 - 50 nm.  Citrate-capped nanoparticles are very stable. Citrate-capping can be easily functionalized with various ligands, such as peptides, DNA,  and antibodies.

    Optical properties

    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 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.
