Characterization of Pseudomonas Aeruginosa Biofilms Grown on Different Substrates by Means of FT-IR Spectroscopy

Engineering Proceedings
Fourier transform infrared spectroscopy (FT-IR) is a vibrational technique largely adopted for the study of bacterial biofilms. FT-IR is a non-destructive method allowing multiple analyses of the same biofilm. Pseudomonas aeruginosa represents a class of
