Table 2.

Average De of several example cell clusters in the S. oneidensis biofilms. The measurements were taken on clusters in the biofilm shown in Figure 4, and the specific clusters chosen are shown in Figure S7 in the ESI. De are given in 10−9 m2/s along with the standard deviation and the relative De in the adjacent column.
