金的纳米粒子粒度分析

Scientific interest in well dispersed suspensions of colloidal gold (or nanoparticles) can be traced back to ancient times. Original uses of colloidal gold included potions, stained glass,and other artistic expressions. Current research using gold dispersions remains quite active and controlling the size and morphology of the particles is critical. Recently, the National Institute of Standards and Technology (NIST) has developed Reference Materials (RMs) of gold nanoparticles that are nominally 10, 30, and 60 nm. This application note describes a procedure and shows results from a study analyzing these NIST RM samples.
