Genetically Encoded Photosensitizers as Light-Triggered Antimicrobial Agents [PDF]
International Journal of Molecular Sciences, 2019 Diseases caused by multi-drug resistant pathogens have become a global concern. Therefore, new approaches suitable for treating these bacteria are urgently needed. In this study, we analyzed genetically encoded photosensitizers (PS) related to the green fluorescent protein (GFP) or light-oxygen-voltage (LOV) photoreceptors for their exogenous ...
