Betel leaf-mediated zinc oxide nanoparticle-coated silk fibres: a sustainable approach for biomedical applications.

Clinical management of surgical site infections remains a challenge in biomedicine, where novel wound dressing materials are tested with a plethora of features. Here we describe a green and sustainable route to prepare biogenic zinc oxide nanoparticles (BZnONPs) using leaf extract, which acts as a green reducing and stabilising agent. These biosynthesised nanoparticles were then used for the functional coating of degummed silk fibers.
