659Mn/Ni(OH)x LDHs75.9nmTEMAfter the coating procedure, transmission electron microscope (TEM) image in Figure 1b reveals a rough surface for the colloids, indicating the successful coating a layer of Mn/Ni-LDH on silica colloids. The thickness of the shell is ≈75.9 nm (Figure S2, Supporting Information).
659Mn/Ni(OH)x LDHs37nmTEMAfter the LDHs surface coating, Figure 1f,g; and Figure S6 (Supporting Information) reveals a rough surface for these silica rods. The shell thickness of the LDH coated on the silica rods is highly homogeneous with a value of ≈37 nm (Figure 1f).

659Colloidal Surface Engineering: Growth of Layered Double Hydroxides with Intrinsic Oxidase‐Mimicking Activities to Fight Against Bacterial Infection in Wound Healinghttps://doi.org/10.1002/adhm.202000092CompositeHere, a layer of Mn/Ni layered hydroxides (Mn/Ni(OH)x LDHs) can be successfully coated on various colloidal particles, such as silica spheres, silica rods, ferrite nanocrystal supraparticles, as well as FeOOH nanorods. Such layered hydroxides have intrinsic oxidase-mimetic activities, as demonstrated by catalytic oxidation of tetramethyl benzidine in the presence of oxygen.
