Figure 1
ESI mass and TEM image of the Au25(4ATP)18 clusters. The ESI-MS data spectrum was measured using a SYNAPT G2S-HDMS mass spectrometer equipped with an electrospray ionization source and TEM characterization was carried out using a FEI Tecnai G2 Spirit instrument operating on an acceleration tension of 120 kV. Clusters are dispersed in DMSO for analysis. |
