Figure 3

(A): (a) shows polyurethane layer imprinted with the artificial stamp of E. coli; (b) sectional view for accessing depth of imprinted cavities; (c) 3D image of polyurethane layer; (B) presents cross-sensitivity of two different sensor layers imprinted with E. coli B and W strains, respectively, it is clear that both layers showed higher sensor effects to E. coli strain, which was used as a template for imprinting and minimal response to non-target strain, adapted from [105].
