“…27 Moreover, as we have recently demonstrated, combination of AF4 with online molecular (MALS) and elemental (ICP-MS/MS) detectors is an invaluable tool to characterize nanostructures since it can separate them (AF4), determine their hydrodynamic size (MALS), quantify the elemental composition and determine stoichiometries and molar ratios (ICP-MS/MS) all together in one single analysis. 29 The optimum AF4-MALS-ICP-MS/MS instrumental conditions are shown in Tables S1 and S2. † CD-MO@UiO66 nano-MOFs and pure cisplatin were separately injected and analyzed, and the fractograms are shown in Fig.…”
