Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Acacia nilotica (L.) Wild. Ex Delilie is a shrub with significant ethnomedicinal stature. Therefore, in the undertaken study, its wound healing attributes are determined. AIM OF THE STUDY The current study provided evidence of the traditional use of A. nilotica species and conferred A. nilotica bark extract as a potent candidate for wound healing agents. MATERIALS & METHODS A. nilotica leaves extract (ANL-E); A. nilotica bark extract (ANB-E), and A. nilotica stem extract (ANS-E) were prepared using methanol-chloroform (1:1). Phytochemical analysis was performed using gallic acid equivalent (GAE) total phenolic content (TPC), quercetin equivalent (QE) total flavonoid content (TFC) assays and High-performance liquid chromatography (HPLC). In vitro antioxidant potential (free radical scavenging activity (FRSA), total antioxidant capacity (TAC), and ferric reducing antioxidant power (FRAP) assay), antibacterial activity (broth microdilution method) and hemolytic analysis was carried out. Wound healing proficiency of ANB-E was determined by wound excision model followed by estimating hydroxyproline content and endogenous antioxidant markers. RESULTS Maximum phenolic and flavonoid content were depicted by ANB-E i.e., 50.9 ± 0.34 μg gallic acid equivalent/mg extract and 28.7 ± 0.13 μg quercetin equivalent/mg extract, respectively. HPLC analysis unraveled the presence of a significant amount of catechin in ANL-E, ANB-E and ANS-E (54.66 ± 0.02, 44.9 ± 0.004 and 31.36 ± 0.02 μg/mg extract) respectively. Highest percent free radical scavenging activity, total antioxidant capacity, and ferric reducing action power (i.e., 93.3 ± 0.42 %, 222.10 ± 0.76, and 222.86 ± 0.54 μg ascorbic acid equivalent/mg extract) were exhibited by ANB-E. Maximum antibacterial potential against Staphylococcus aureus was exhibited by ANB-E (MIC 12.5 μg/ml). Two of the extracts i.e., ANL-E and ANB-E were found biocompatible with less than 5 % hemolytic potential. Based upon findings of in vitro analysis, ANB-E (10, 5, and 2.5 % w/w, C1, C2, and C3, respectively) was selected for evaluating its in vivo wound healing potential. Maximum contraction of wound area and fastest epithelization i.e., 98 ± 0.05 % and 11.2 ± 1.00 (day) was exhibited by C1. Maximum hydroxyproline content, glutathione, catalase, and peroxidase were demonstrated by C1 i.e., 15.9 ± 0.52 μg/mg, 9.3 ± 0.17 mmol/mg, 7.2 ± 0.17 and 6.2 ± 0.14 U/mg, respectively. Maximal curbed lipid peroxidation i.e., 0.7 ± 0.15 mmol/mg was also depicted by C1. CONCLUSIONS In a nutshell, the current investigation endorsed the wound healing potential of ANB-E suggesting it to be an excellent candidate for future studies.

Abstract
The intricate healing process of skin wounds includes a variety of cellular and molecular events. Wound healing heavily relies on reactive oxygen species (ROS), which are essential for controlling various processes, including inflammation, cell growth, angiogenesis, granulation, and the formation of extracellular matrix. Nevertheless, an overabundance of reactive oxygen species (ROS) caused by extended oxidative pressure may result in the postponement or failure of wound healing. It is crucial to comprehend the function of reactive oxygen species (ROS) and create biomaterials that efficiently eliminate ROS to enhance the healing process of skin wounds. In this study, a thorough examination is presented on the role of reactive oxygen species (ROS) in the process of wound healing, along with an exploration of the existing knowledge regarding biomaterials employed for ROS elimination. In addition, the article covers different techniques and substances used in the management of skin wound. The future prospects and clinical applications of enhanced biomaterials are also emphasized, highlighting the potential of biomaterials that scavenge active oxygen to promote skin repair. This article seeks to enhance the understanding of the complex processes of ROS in the healing of wounds and the application of ROS-scavenging materials. Its objective is to create novel strategies for effective treatment skin wounds.

Abstract
Hydrogels represent intricate three-dimensional polymeric structures, renowned for their compatibility with living systems and their ability to naturally degrade. These networks stand as promising and viable foundations for a range of biomedical uses. The practical feasibility of employing hydrogels in clinical trials has been well-demonstrated. Among the prevalent biomedical uses of hydrogels, a significant application arises in the context of wound healing. This intricate progression involves distinct phases of inflammation, proliferation, and remodeling, often triggered by trauma, skin injuries, and various diseases. Metabolic conditions like diabetes have the potential to give rise to persistent wounds, leading to delayed healing processes. This current review consolidates a collection of experiments focused on the utilization of hydrogels to expedite the recovery of wounds. Hydrogels have the capacity to improve the inflammatory conditions at the wound site, and they achieve this by diminishing levels of reactive oxygen species (ROS), thereby exhibiting antioxidant effects. Hydrogels have the potential to enhance the growth of fibroblasts and keratinocytes at the wound site. They also possess the capability to inhibit both Gram-positive and Gram-negative bacteria, effectively managing wounds infected by drug-resistant bacteria. Hydrogels can trigger angiogenesis and neovascularization processes, while also promoting the M2 polarization of macrophages, which in turn mitigates inflammation at the wound site. Intelligent and versatile hydrogels, encompassing features such as pH sensitivity, reactivity to reactive oxygen species (ROS), and responsiveness to light and temperature, have proven advantageous in expediting wound healing. Furthermore, hydrogels synthesized using environmentally friendly methods, characterized by high levels of biocompatibility and biodegradability, hold the potential for enhancing the wound healing process. Hydrogels can facilitate the controlled discharge of bioactive substances. More recently, there has been progress in the creation of conductive hydrogels, which, when subjected to electrical stimulation, contribute to the enhancement of wound healing. Diabetes mellitus, a metabolic disorder, leads to a slowdown in the wound healing process, often resulting in the formation of persistent wounds. Hydrogels have the capability to expedite the healing of diabetic wounds, facilitating the transition from the inflammatory phase to the proliferative stage. The current review sheds light on the biological functionalities of hydrogels, encompassing their role in modulating diverse mechanisms and cell types, including inflammation, oxidative stress, macrophages, and bacteriology. Additionally, this review emphasizes the significance of smart hydrogels with responsiveness to external stimuli, as well as conductive hydrogels for promoting wound healing. Lastly, the discussion delves into the advancement of environmentally friendly hydrogels with high biocompatibility, aimed at accelerating the wound healing process.

Abstract
An optimal wound-healing hydrogel requires effective antibacterial properties and a favorable cell adhesion and proliferation environment. AlthoughBombyx morisilk fibroin (SF) possesses inherent wound-healing properties, it lacks these essential qualities. This study aimed to fabricate a novel photo-polymerizable hydrogel by utilizing SF's wound-healing efficiency and the epsilon-poly-L-lysine (EPL) antimicrobial activity. The SF was modified with three different concentrations of glycidyl methacrylate (GMA) to obtain SF-GMA(L), SF-GMA(M), and SF-GMA(H). A methacrylated EPL (EPL-GMA) was also produced. Then, SF-GMA was mixed with EPL-GMA to produce photo-crosslinkable SF-GMA-EPL hydrogels. The SF-GMA(L)-EPL, SF-GMA(M)-EPL, and SF-GMA(H)-EPL hydrogels, fabricated with 20% EPL-GMA, demonstrated maximum antimicrobial activity and mammalian cell adhesion ability. The hydroxyl radical (•OH) scavenging efficiency of the hydrogels was tested and shown to be between 69% and 74%. These hydrogels also exhibited 60% efficiency in removing bacterial lipopolysaccharides. The water absorption ability of the hydrogels was consistent with the size of their internal pores. The hydrogels exhibited a slow degradation fashion, and their degradation products appeared cytocompatible. Finally, the elastomeric properties of the hydrogels were determined, and a storage modulus (G') of 300-600 Pa was demonstrated. In conclusion, the hydrogels created in this study possess excellent biological and physical properties to support wound healing.

Abstract
Repairing the wound is a multistep process that includes the spatial and temporal synchronization of a different range of cell types to increase the speed of wound contraction, the proliferation of epithelial cells, and collagen formation. The need for proper management of acute wounds to be cured and not turned into chronic wounds is a significant clinical challenge. The traditional practice of medicinal plants in many regions of the world has been used in wound healing since ancient times. Recent scientific research introduced evidence of the efficacy of medicinal plants, their phyto-components, and the mechanisms underlying their wound-repairing activity. This review aims to briefly highlight the wound-curing effect of different plant extracts and purely natural substances in excision, incision, and burn experimental animal models with or without infection of mice, rats (diabetic and nondiabetic), and rabbits in the last 5 years. The in vivo studies represented reliable evidence of how powerful natural products are in healing wounds properly. They have good scavenging activity against Reactive oxygen species (ROS) and anti-inflammatory and antimicrobial effects that help in the process of wound healing. It is evident that incorporating bioactive natural products into wound dressings of bio- or synthetic polymers in nanofiber, hydrogel, film, scaffold, and sponge forms showed promising results in different phases of the wound-curing process of haemostasis, inflammation, growth, re-epithelialization, and remodelling.
