Antibacterial Cu-doped cotton textile against respiratory pathogens for preventing hospital-acquired infections.

ABSTRACT: Respiratory pathogens transmitted via clinical textiles represent a major source of hospital-acquired infections, yet current antibacterial fabric strategies are limited by poor durability and weak bacterial inhibition. Here, we reported a molecular-level strategy for the fabrication of copper-doped antibacterial cotton textiles (Cu@textile) via a simple immersion of common cotton in a Cu(II)-saturated NaOH solution. This process enabled stable coordination between the copper ions and cellulose hydroxyl groups, forming stable Cu-O bonds throughout the fiber matrix. Structural and spectroscopic analyses confirmed uniform copper integration and chemical bonding. The resulting Cu@textile exhibited potent, broad-spectrum antibacterial activity against key respiratory pathogens, i
