Figure 7

Structural representations of (6) cytochrome c (Cyt c) labelled MSNs with 10 mol% carboxyl coating; (7) cytochrome c labelled MSNs with 1 mol % primary amine coating; (8) cytochrome c labelled MSNs with 0.25 mol% primary amine coating; (9) acid-responsive cytochrome c labelled MSNs with 1 mol% primary amine coating; (10) reductant cleavable-responsive cytochrome c labelled MSNs with 1 mol% primary amine coating; (11) BSA or lysozyme labelled MSNs with 1 mol% primary amine coating. A summary of hydrodynamic diameter (dhyd), polydispersity index (PDI), ζ potential at two relevant pH boundaries, charging capacity and cytosol accessibility is also included for each particle type.
