Standard Reference Materials of Nanoparticle with Diameter of a Few Nanometers

Abstract

Current status of the calibration standard materials in the size range of a few nanometers is reviewed. The techniques for aerosolizing the monodisperse nanoparticles are described, and the method for size determination of gasborne nanoparticles is discussed when differential mobility analyzers (DMA) are used. Additionally, some candidates of size standard nanoparticles in the range of a few nanometers such as fullerenes, dendrimers, globular proteins and tetra-alkyl ammonium ions are reported.
