New Smart Polymeric Materials with Optical Sensing Properties: Determination of Antimicrobial Properties Using Photodynamic Therapy

Antimicrobial resistance has intensified the search for non-antibiotic strategies activated by external stimuli, including antimicrobial photodynamic therapy. In this work, a hybrid system based on spiropyran-functionalized poly(maleic anhydride-alt-acrylic acid), P(MAn-alt-AA)-SP, and CdTe@ZnS quantum dots incorporate...

Antimicrobial photodynamic therapy across ESKAPE pathogens: Efficacy, limitations, and a pathogen-adapted framework toward clinical translation.

Multidrug-resistant (MDR) bacteria belonging to the ESKAPE group-Enterococcus spp., Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter spp.-represent some of the most urgent threats to global health. These pathogens are major causes of healthcare-associated i...

Photodynamic antimicrobial efficacy and mode of action of polypyridyl-based Ru(II) complexes against multidrug-resistant Klebsiella pneumoniae.

Ruthenium-based photosensitisers appear to act predominantly through singlet oxygen-mediated oxidative stress, enhancing cefotaxime efficacy while exhibiting low cytotoxicity, and therefore represent promising adjunct therapies against MDR K. pneumoniae.
