AF4-ICP-MS as a powerful tool for the separation of gold nanorods and nanospheres

An analytical methodology based on asymmetric flow field flow fractionation (AF4) hyphenated to inductively coupled plasma mass spectrometry (ICP-MS) has been developed to separate gold nanorods (AuNRs) and nanospheres (AuNSs). This separation is of special interest because the latter are the main i...

Sumario:An analytical methodology based on asymmetric flow field flow fractionation (AF4) hyphenated to inductively coupled plasma mass spectrometry (ICP-MS) has been developed to separate gold nanorods (AuNRs) and nanospheres (AuNSs). This separation is of special interest because the latter are the main impurity in the synthesis of AuNRs by seeding growth procedures, and quality control tools are highly demanded.
