Trichophyton rubrum is one of the most common dermatophytes, which can cause fungal nail and ringworm infections. Infections associated with T. rubrum have become a global phenomenon. Herein, we report the antifungal photodynamic inactivation of T. rubrum (ATCC 28188) using the mesoporous silica-coated silver nanoparticle-based hybrid photosensitizers without involving antifungal drugs. Results show that the hybrid photosensitizers display low cytotoxicity under the experimental conditions where significant killing (~3 orders of magnitude) against T. rubrum is observed. These results demonstrate the potential applications of the nanoparticle-based hybrid photosensitizers in antifungal photodynamic therapy against T. rubrum.
