Abstract
We report a photosensitive polymyxin B-modified conjugated oligomer nanoparticle that integrates the targeted identification and synergistic photodynamic therapy in one treatment against resistant Gram-negative bacteria. The study expands the application of antibiotics and opens a new avenue for enhancing photodynamic antimicrobial therapy and fighting bacterial resistance.
