This study reported the efficacy of carboxymethyl cellulose-based topical gels loaded with a combination of essential oils and silver nanoparticles as potential wound dressings for bacterial-infected wounds. The gels displayed promising antibacterial activity and excellent wound closure in vitro, indicating their potential clinical applications.
Aim: Essential oils are promising antibacterial and wound-healing agents that should be explored for the design of wound dressings. Materials & methods: Topical gels prepared from a combination of carboxymethyl cellulose and poloxamer were incorporated with tea tree and lavender oil together with Ag nanoparticles. In vitro release, cytotoxicity, antibacterial, and wound healing studies were performed. Results: The gels displayed good spreadability with viscosity in the range of 210-1200 cP. The gels displayed promising antibacterial activity against selected Gram-positive and Gram-negative bacteria used in the study. The % cell viability of the gels was more than 90.83%. Conclusion: The topical gels displayed excellent wound closure in vitro revealing that they are potential wound dressings for bacteria-infected wounds. Plain language summary What is this article about?This article reports the efficacy of carboxymethyl cellulose-based topical gels loaded with a combination of essential oils and silver nanoparticles as potential wound dressings for bacterial-infected wounds. What were the results?The topical gels induced a faster rate of closure than the untreated cells in 96 h. The gel formulations did not induce any significant cytotoxic effect. They were effective against Gram-negative and Gram-positive bacteria used in the study. What do the results of the study mean?The topical gels displayed promising healing effects in vitro revealing that they are potential wound dressings for treating bacteria-infected wounds. Tweetable abstractCMC-based topical gels loaded with a combination of essential oils and silver nanoparticles are promising wound dressings for treating bacterial-infected wounds.
