Sonophotodynamic Inactivation: The power of light and ultrasound in the battle against microorganisms

Journal of Photochemistry and Photobiology, 2021
The inactivation of pathogenic microorganisms that are a threat to the human being is an old challenge that needs to be overcome, mainly because microorganisms are able to develop resistance that leads to the failure of the treatment.

Synergistic effect of hypocrellin B and curcumin on photodynamic inactivation of Staphylococcus aureus

Microbial Biotechnology, 2021
Summary Antimicrobial photodynamic inactivation (aPDI) serves as a new approach to control the growth of foodborne bacteria. It remains elusive if the photodynamic efficacy of hypocrellin B (HB) can be potentiated by joint action with curcumin.
