Scaling up the sono-enzymatic coating of cotton textiles with antimicrobial silver-phenolated lignin nanocomposites.

ABSTRACT: The pressing demand for controlling infections in healthcare facilities has prompted the development of highly efficient antimicrobial textiles. Herein, we present a simple and scalable approach for engineering durable antimicrobial cotton textiles using a single-step sono-enzymatic process. The coating process involves simultaneous laccase enzyme-catalysed gallic acid (GA) oxidation under ultrasonic conditions (20 kHz frequency, 17.30 W/cm² power intensity, 35 % amplitude, 50 °C, 30 min) using a Ti-horn ultrasonic transducer, generating a bio-based adhesive network that engages both GA and the oxidised phenolic shell of antimicrobial silver phenolated lignin nanoparticles (AgPLNPs), and their deposition on the fabrics. Three coating formulations were investigated: cotton fabric
