Extended Data Fig. 8: Colloidal stability.
DLS measurements of colloidal solutions of silicalite-1 (a), ZSM-5 (b), (mPEG)ZIF-8 (c) and BSA/ZIF-67 (d) nanocrystals in water before and after 1 week of stability testing. The starting solutions contained 11.5 vol% silicalite-1, 34.4 vol% ZSM-5, 8.3 vol% (mPEG)ZIF-8 and 3.4 vol% BSA/ZIF-67. The samples were diluted 70-fold (for silicalite-1), 230-fold (for ZSM-5) and tenfold (for (mPEG)ZIF-8) to obtain accurate DLS data. PXRD patterns before and after dispersion in H2O are shown for 98-nm silicalite-1 nanocrystals (11.5 vol%) (e), ZSM-5 (34.4 vol%) (f), (mPEG)ZIF-8 nanocrystals (8.3 vol%) (g) and BSA/ZIF-67 (3.4 vol%) (h). All samples were dispersed for 1 week before PXRD characterization apart from (mPEG)ZIF-8, which was taken after 2 weeks of dispersion.
