Cover proposal related to the work "Photodynamic Inactivation of ESKAPE Group Bacterial Pathogens in Planktonic and Biofilm Cultures Using Metallated Porphyrin-Doped Conjugated Polymer Nanoparticles" by Sol R. Martínez, Luis E. Ibarra, Rodrigo A. Ponzio, María V. Forcone, Ana B. Wendel, Carlos A. Chesta, Mariana B. Spesia, and Rodrigo E. Palacios. In this work, they studied Photodynamic inactivation (PDI) protocols using photoactive metallated porphyrin-doped conjugated polymer nanoparticles (CPNs) and blue light to eliminate multidrug-resistant pathogens.
