The pH of a wound site can undergo a significant change from its normal range of 5.4–5.6 to a more alkaline environment of 7.2–8.9 after being infected by microorganisms. Therefore, the development of a smart material that can respond to this shift in pH and release antimicrobial agents for effective treatment of wound infections holds great promise for the future of wound care. In the present work, we produced 3D printed alginate wound dressings doped with calcium phosphate nanoparticles (CaP NPs), referred to as alginate-CaP nanocomposites hereafter. The CaP NPs enabled pH-responsive switching of the degradation and drug release of…
