Description
Summary:► Develop a novel antimicrobial paper. ► Cellulosic paper grafted with photosensitizers by covalent bonding using triazine. ► Strategy avoids preliminary chemical modification of the cellulosic material. ► Strong photoantibacterial activity against S. aureus and E. coli. We report on the synthesis of cellulose paper bearing a cationic porphyrin, designed for antimicrobial applications. Tricationic porphyrin has been covalently grafted on paper, without previous chemical modification of the cellulosic support, using 1,3,5-triazine derivative as linker. The obtained porphyrin-grafted paper was characterized by infrared (ATR-FTIR), UV–visible and diffuse reflectance UV–vis (DRUV) spectroscopies to confirm the triazine linkage. Thermogravimetric analysis (TGA) was used to investigate thermal properties of grafted paper. Antimicrobial activity of porphyrin–cellulose material was tested under visible light irradiation against Staphylococcus aureus and Escherichia coli. The two bacterial strains deposited on the resulting photosensitizing filter paper are efficiently killed after illumination.
