Infection microenvironment-responsive guanidine-modified nanostructures for precision photothermal therapy of diabetic wounds.
Diabetic wounds are among the most challenging complications of diabetes, particularly when persistent bacterial biofilms sustain infection, oxidative stress, and inflammation. Here, we developed an infection-microenvironment-responsive nanotherapeutic platform (AuNCs@PGD) by associating guanidine-rich PGD polymers wit...
