Evaluation of biogenic nanosilver-acticoat for wound healing: A tri-modal in silico, in vitro and in vivo study

Wound healing is a complex process that involves numerous biological and physiological events and is influenced by various local and systemic factors. Chronic wounds affect around 6 million people and pose a significant clinical challenge for healthcare professionals, particularly in light of the increasing difficulty in treating wound infections with conventional antibiotics. Conventional wound dressings have several limitations, including insufficient antibacterial potency, toxicity, failure to deliver adequate moisture to the wound, and poor me-chanical properties. Silver nanoparticles (AgNPs) have shown great promise in wound healing due to their exceptional antibacterial properties. In this study, AgNPs were synthesized via green synthesis using Camellia sinensis and Ocimum sanctum and characterized by various techniques. The AgNPs were incorporated into carrageenan to develop nanosilver acticoat for wound healing applications. The anti-bacterial property of the acticoat was tested against S. aureus and E. coli bacteria, and in vivo studies showed that dressing with Carrageenan silver nanoparticles (CAgNPs) acticoat promoted wound healing and had good reepithelialization and dense collagen deposition capabilities. With a significance level of < 0.05, we used one-way ANOVA to analyze the means between groups. In silico analysis with pkCSM and SwissADME provided information on the drug-likeness and human health hazard-related predictions for the prepared formulations. The study highlights the potential of the prepared CAgNPs acticoat for dressing applications in the burn, accidental, and diabetic wound infections. These results suggest that the use of CAgNPs acticoat can provide a safe and effective alternative to conventional wound dressings in promoting wound healing.

Automated summary

This study synthesized silver nanoparticles using green synthesis and developed a silver nanoparticle acticoat by incorporating them into carrageenan for wound healing. The acticoat showed excellent antibacterial properties and promoted wound healing and collagen deposition. The in vivo studies demonstrated its potential application in burn, accidental, and diabetic wound infections.
