(a) Integrated FTIR amide A peak intensities for different incubation times and concentrations of E. coli antibodies prepared in PBS buffer (pH 7.4) on MHDA/MUDO (1:9) functionalized samples. (b) Surface coverage with E. coli bacteria immunocaptured on the biofunctionalized surface, determined by fluorescence microscopy for different concentrations and incubation times of E. coli antibodies (n = 3 samples per concentration and incubation duration).
