Özet
The main purpose of this work is to obtain a cotton-based textile material functionalized with L-cysteine (L-cys) to achieve an antimicrobial effect with potential application in biomedical, geriatric or pediatric textiles. The binding capacity of L-cys to cotton fibres was assessed through different functionalization strategies surface activation and exhaustion processes. A subsequent analysis of the possible antibacterial action against Staphylococcus aureus and Klebsiella pneumoniae was performed according with the Japanese International standard (JISL, 2008). To determine the mechanism of action of L-cys on the selected strains, flow cytometry was used.
