Measurement of Gold Nanoparticle Size and Concentration by Spectrophotometry

by Andrew F. Page, PhD
Although gold nanoparticle production can be controlled to yield specific size ranges, both the concentration and size of nanoparticles must be checked following production. UV-Vis spectrophotometry is an established QC method for this; however cuvette spectrophotometers often require dilution of the nanoparticle solution before measuring, and volumes up to 3 mL.
