Antimicrobial drug-derived carbon quantum dots for photodynamic therapy of bedsores and bacterial infections

This work demonstrates a novel paradigm for transforming antimicrobial drugs into multifunctional N, CQ-dots, leveraging preserved pharmacophores and PDT mechanisms to overcome drug resistance. The system combines intrinsic antibacterial activity with light-triggered responsiveness, offering a promising solution for managing infected bedsores while minimizing systemic toxicity. These findings highlight the translational potential of drug-derived nanomaterials in precision wound care.
