Nanopartz^TM Accurate^TM brand spherical gold nanoparticles (SGNPs) 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 Certificate of Analysis product document that accompanies each order.  For conjugated spherical gold nanoparticles go to our Conjugated Accurate SGNPS.

Composition

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

 

Sizing

WE

Every batch is measured for size, polydispersity and charge using our Malvern Nano ZS DLS using ASTM Standard E 2490-09. Results from these measurements are provided in an enclosed  Certificate of Analysis.
