Figure 5

SEM images of anti-MEA FMNs at 40000× (a) and 90000× (b) magnification showing cube-like FMNs. The scale bars represent 1 μm and 500 nm, respectively. Aggregation of bacterial cells surrounded with anti-MEA FMNs for C. jejuni (c) and C. coli (d) cells. Some small part of the cell surface was free from the anti-MEA FMNs, as indicated by an arrow. The bar represents 2 μm.
