The Effect of Bacterial Adhesion on Grafted Chains Revealed by the Non-Invasive Sum Frequency Generation Spectroscopy
Figure 1
(a) Experimental (blue dots) and fitted (red lines) SFG spectrum of an ODT SAM in distilled water. The SFG reference spectrum (purple dashed line) is also presented. (b) Deconvoluted vibrational bands of an ODT SAM in distilled water (lines), in the presence of hydrophobic L. lactis bacteria PRTP+ (pink dashed lines), and in the presence of hydrophilic L. lactis bacteria (green lines) in distilled water after 90 minutes of adhesion.
