Biofilm-induced chronic bacterial infections represent a significant challenge in modern medicine due to their resistance conventional antibiotic treatments. Although photodynamic therapy (PDT) has emerged as promising antibiotic-free antibacterial strategy, the hypoxic condition within biofilms and lack of an effective local drug delivery system have limited clinical effectiveness photosensitizer (PS) agents. Herein, we propose type charge regulation-enhanced I PS-loaded hydrogel dressing for treating biofilm infection. The regulation enables multiple alkylation Nile blue (EB series) exhibit substantially improved absorbance (∼2-fold), alkaline tolerance, superoxide anion yield (2.2-4.2-fold) compared representative PS, sulfur-substituted blue. Specifically, enhanced electronic push-pull capabilities promote more efficient electron recycling process, significantly boosting efficiency PDT. superior PDT effect uptake via render EB series pronounced inhibition under red light or sunlight irradiation. Moreover, hydrogel, constructed from oxidized dextran quaternized chitosan, facilitates localization sustained retention PSs, accelerating healing biofilm-infected wounds.
