Abstract
Three approaches for the chemical ligation of peptides to cotton fibers are described and compared. This investigation was encouraged by the need to create peptide-decorated natural textiles, furnished with useful properties (e.g. antimicrobial activity). IR absorption spectroscopy is proved to be an easy and fast method to check the covalent anchorage of a peptide to cotton, whereas for a quantitative determination, a UV absorption method was employed. We also analyzed the usefulness of electron paramagnetic resonance spectroscopy to characterize our peptide-cotton conjugates.
