摘要: Recent advances in cluster synthesis make it possible to produce an enormous variety molecule-like MPCs of size, composition, shape, and surface-chemical combinations. In contrast the significant growth synthetic capability generate these materials, progress establishing physicochemical basis for their observed properties has remained limited. The main reason this been lack analytical measure samples suitably high (molecular) purity; such is also essential support therapeutic diagnostic MPC development. order products get market, especially those that are medical-field related, characterization required identify quantify all components present a material mixture. Here, we show results from analysis several mixtures gold by nonaqueous reversed-phase chromatography coupled with mass spectrometry detection. additional or hidden components, revealed be prese...
