Front Cover . Photodynamic effect mediated by the monobrominated Neutral Red and visible light irradiation in Staphylococcus aureus cells could be mediated by a contribution of Type I and Type II processes since the results obtained showed that the compound produced reactive oxygen species and a contribution of singlet molecular oxygen cannot be discarded. However, the mechanistic evaluation of Neutral Red showed that it is a producer of radical species, acting through a type I mechanism. These results explain the differences observed in the photoactivation of Staphylococcus aureus mediated by both azine photosensitizers as reported by Urrutia et al . in their communication at 10.1002/cbdv.201900262.
