Abstract

The development of eco-friendly prototypes for wound dressing systems represents an important source of investigation about alternatives for the treatment of severe infections. The production of antibacterial agents free of antibiotics, based on natural products and biological supports is a hot topic for science applied in circular economy concepts. Herein, the green synthesis of silver nanoparticles was assisted by essential oil and the following impregnation of products in tilapia skin has been conducted as a strategy to produce all-green wound dressing systems to be applied as biofilm protective layers and active antibacterial agents. The use of these wound dressing systems against Staphylococcus aureus was evaluated in terms of biofilm adhesion, inhibition halo assays, and time-kill assays as a function of the nature of reducing agent applied in the production of silver nanoparticles.
