All-green wound dressing prototype based on Nile tilapia skin impregnated with silver nanoparticles reduced by essential oil

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.

Polyethylene glycol dictates the therapeutic response (anticancer and wound healing) of silver oxide nanomaterials

“…The gels were modified by dipping in distilled water for 5 min and then bare and coated silver oxide NPs were uniformly distributed on the gels. These modified gels were then pasted on the cut part of the egg shells and wound healing properties have been determined 74 . Figure 9A–E shows the photographs taken on day 15 after applying silver oxide‐incorporated gels on fertilized eggs.…”

Antibacterial activity of molybdenum disulfide and green silver nanoparticles reduced by tea tree essential oil compounds

“…Discs formed by liquid samples of MoS2, AgNPs, and the MoS2+AgNPs association were incorporated into the plates to assess their activity. After this step, the plate was incubated at 37 °C for 24 h (Milena Lima Guimarães et al, 2022b).…”

“…To circumvent these drawbacks, the green synthesis of silver nanoparticles has been considered an environmentally friendly process that considers the use of materials (such as extracts of plants and essential oils) that are rich in terpenes and flavonoids being relevant in the reduction of Ag + to Ag 0 (M.L. Guimarães et al, 2020;Milena Lima Guimarães et al, 2019, 2022aVinicius de Oliveira Brisola Maciel et al, 2020).…”
