Spherical Gold Nanoparticles

Nanopartz Accurate Spherical Gold Nanoparticles

NanopartzTM AccurateTM brand spherical gold nanoparticles are manufactured using a proprietary and patent pending method that results in exact sizes, highly monodisperse sizes and shapes, along with significantly improved reactivity.  Sizes are 5-100 nm in increments of 5 nm.  Every batch is measured for size, monodispersity, and concentration.  See our typical SGNP QA/QC product documents.  For conjugated spherical gold nanoparticles go to our Conjugated Accurate SGNPS.

Accurate Spherical Gold Nanoparticles do not

Composition


Gold colloid with < 0.1% carboxylic acid functionalized hydrocarbon capping agent and < 0.1% hydroxide in distilled water.
