Analytical Separation of Ultrasmall Water-Soluble Gold Nanoclusters by HPLC and CE
Gold nanoparticles (AuNPs),protected from metal-metal aggregation by self-assembled monolayers,constitute a rapidly emerging field of chemical research.Distinctive features of the current trend in the area of nanoresearch focus mainly on the synthesis of NPs of controlled size,shape,and surface chemistry.Unfortunately,most samples of AuNPs are a complex mixture of components made up of various Au cores and different numbers of protected ligands.A polydisperse NP sample only represents the summation or average properties of all individual NP.The complexity of synthetic AuNP samples can be so great that efficient analytical separation approaches have to be employed.
