Figure 3From: Molecular response of Escherichia coli adhering onto nanoscale topographyResults of RT-qPCR. RNA expression level (%), by RT-qPCR, of E. coli growing onto flat (left histograms) and nanorough (right histograms) substrates. All data relative to PCR experiments were analyzed by a statistical software to evaluate the significant difference with respect to the control (a star indicates p value = 0.001).Back to article page
