Electronic Supplementary Information (ESI) available: Evolution of the absorbance of 1,3-diphenylisobenzofuran (DBF) and curcumin alone at 480 nm in acetonitrile under visible light illumination and emission spectrum of the 4 lamps used during the different incubation times. SeeThe development of new antibacterial coating (against Escherichia coli and Staphylococcus aureus) with the use of a natural dye (curcumin) and epoxidized soybean oil, according to a photochemistry process has been investigated.Curcumin has been used both as a photosensitizer and an antibacterial agent under visible light illumination. The photoinduced coatings show good adherence properties on inox substrate and a high thermal stability by 375°C. Under visible light activation, singlet oxygen ( 1 O2) could be generated from the curcumin derivative-coatings, thus inhibiting by 99% and 95% the growth of Staphylococcus aureus and Escherichia coli, respectively, even after 48h of incubation.
