Curcumin is known for its antimicrobial effects. Here we use the atomic/molecular layer deposition (ALD/MLD) thin‐film technique to embed monomolecular curcumin layers within a photocatalytic TiO 2 matrix into different superlattice structures with the anticipation of intriguing synergistic effects. We demonstrate the extension of the light absorption to the entire visible range which could pave the way for the use of these films for light‐driven destruction of pathogens.
