Chiral Gold Nanoparticles
NanoSeedz™ provides CTAB-capped chiral plasmonic gold nanoparticle products. The synthesis of each batch is precisely controlled. The samples are independently characterized and examined by extinction spectroscopy before delivery. The samples with the same label vary very slightly from batch to batch.
