Abstract: ) during periods covering between 30 and 120 min, according to the tested microorganism. Tests performed with textiles to evaluate the persistence of the RB color in them and their capability to photosensitize the inactivation of microorganisms revealed that the CF improves the robustness of the fabric. Furthermore, the photophysical and photodynamic properties of the fabrics were evaluated by direct and indirect methods. In this context, the formation of photoactivable complexes was observed through the association of RB with CF. Moreover, it was established that the remarkable photodynamic efficiency using the fabric with CF is produced through an electron transfer from microorganisms to an excited RB-CF complex (Type I) and singlet oxygen generated from the triplet excited state of free RB (Type II).
