Core-shell nanofibers have great potential for bio-medical applications such as wound healing dressings where multiple drugs and growth factors are expected to be delivered at different healing phases. Compared to monoaxial nanofibers, core-shell nanofibers can control the drug release profile easier, providing sustainable and effective drugs and growth factors for wound healing. However, it is challenging to produce core-shell structured nanofibers with a high production rate at low energy consumption. Co-axial centrifugal spinning is an alternative method to address the above limitations to produce core-shell nanofibers effectively. In this study, a co-axial centrifugal spinning device was designed and assembled to produce core-shell nanofibers for controlling the release rate of ibuprofen and hEGF in inflammation and proliferation phases during the wound healing process. Core-shell structured nanofibers were confirmed by TEM. This work demonstrated that the co-axial centrifugal spinning is a high productivity process that can produce materials with a 3D environment mimicking natural tissue scaffold, and the specific drug can be loaded into different layers to control the drug release rate to improve the drug efficiency and promote wound healing.

Major Health Problem

Burns can be caused by various factors and have an increased risk of infection that can seriously delay the wound healing process. Chronic wounds caused by burns represent a major health problem. Wound healing is a complex process, orchestrated by cytokines, growth factors, prostaglandins, free radicals, clotting factors, and nitric oxide. Growth factors released during this process are involved in cell growth, proliferation, migration, and differentiation. Reactive oxygen species are released in acute and chronic burn injuries and play key roles in healing and regeneration. The main aim of this review is to present the roles of growth factors, reactive oxygen species, and metformin in the healing process of burn injuries.

Responsive Polymers

Innate and adaptive immune responses lead to wound healing by regulating a complex series of events promoting cellular cross-talk. An inflammatory response is presented with its characteristic clinical symptoms: heat, pain, redness, and swelling. Some smart thermo-responsive polymers like chitosan, polyvinylpyrrolidone, alginate, and poly(ε-caprolactone) can be used to create biocompatible and biodegradable scaffolds. These processed thermo-responsive biomaterials possess 3D architectures similar to human structures, providing physical support for cell growth and tissue regeneration. Furthermore, these structures are used as novel drug delivery systems. Locally heated tumors above the polymer lower the critical solution temperature and can induce its conversion into a hydrophobic form by an entropy-driven process, enhancing drug release. When the thermal stimulus is gone, drug release is reduced due to the swelling of the material. As a result, these systems can contribute to the wound healing process in accelerating tissue healing, avoiding large scar tissue, regulating the inflammatory response, and protecting from bacterial infections. This paper integrates the relevant reported contributions of bioengineered scaffolds composed of smart thermo-responsive polymers for drug delivery applications in wound healing. Therefore, we present a comprehensive review that aims to demonstrate these systems’ capacity to provide spatially and temporally controlled release strategies for one or more drugs used in wound healing. In this sense, the novel manufacturing techniques of 3D printing and electrospinning are explored for the tuning of their physicochemical properties to adjust therapies according to patient convenience and reduce drug toxicity and side effects.

Oxygen Species

Wound healing is a complex dynamic process characterized by a series of events that occur in almost all type of tissue damage. In the early phase of the inflammatory response, neutrophils and macrophages enters into the injured tissue and the cells produce reactive oxygen species that can give a beneficial or detrimental effects. Oxidative stress is a condition occurs that shows imbalance between prooxidant or free radical and antioxidant that have a function to maintain the condition of the tissue damage that occurs. So Oxidative stress occurs when the production of Reactive Oxygen Species occurring is higher than the antioxidants existing as an intrinsic defense. Reactive Oxygen Species and Reactive Nitrogen Species are important components in the healing process of wounds and is necessary to be in the state of homeostasis to prevent oksidatif stress. The major components of ROS are superoxide (O2•), hydroxyl radical (OH•) and hydrogen peroxide (H2O2), which includes RNS are nitric oxide (NO•), nitrous oxide (NO2•), nitroxyl anion (HNO) and peroxynitrite (ONOO-) which could be form by the reaction between superoxide and nitric oxide. The existence of excessive O2 amount in the wound and the presence of excess NO can increase the incidence of oxidative stress that interfere with wound healing process. Oxidative stress plays a role in the inflammatory phase, proliferation and remodeling phase by increasing angiogenesis and affect other cells including endothelial cells in secreting NO. So the strategy in controlling oxidative stress is by increasing antioxidant level which is a scavenger to free radical excessive superoxide formation so preventing interference with the wound healing process.

A wound refers to the epithelial loss, accompanied by loss of muscle fibers collagen, nerves and bone instigated by surgery, trauma, frictions or by heat. Process of wound healing is a compounded activity of recovering the functional integrity of the damaged tissues. This process is mediated by various cytokines and growth factors usually liberated at the wound site. A plethora of herbal and synthetic drugs, as well as photodynamic therapy, is available to facilitate the process of wound healing. Generally, the systems used for the management of wounds tend to act through covering the ruptured site, reduce pain, inflammation, and prevent the invasion and growth of microorganisms. The available systems are, though, enough to meet these requirements, but the involvement of nanotechnology can ameliorate the performance of these protective coverings. In recent years, nano-based formulations have gained immense popularity among researchers for the wound healing process due to the enhanced benefits they offer over the conventional preparations. Hereupon, this review aims to cover the entire roadmap of wound healing, beginning from the molecular factors involved in the process, the various synthetic and herbal agents, and combination therapy available for the treatment and the current nano-based systems available for delivery through the topical route for wound healing.

Wound healing has been the burning problem in a surgical practice because of a remarkable increase in the number of traumatic cases. A wound causes a number of changes in the body that can affect the healing process, including changes in energy, protein, carbohydrate, fat, vitamin and mineral metabolism. Various Ayurveda literatures, particularly, Sushruta Samhita, which is said to be an ancient textbook of surgery in Ayurveda, has mentioned about the diet for the person suffering from the wound, and the author said that diet plays a very important role in the wound healing process. Sushruta - The father of surgery has scientifically classified it in a systemic manner, whose wealth of clinical material and the principles of management are valid even today. Shalya Tantra (surgical branch in Ayurveda Science) is one of the important branch of Ayurveda, in which surgical and para-surgical techniques has described for management of various diseases. Vrana is the most important and widely described chapter of Shalya Tantra. Vrana (wound) is one of them, which have been managed by human being from starting of civilization. Under the circumstances, the first thing which the men came across was the injury from different sources which caused him the Vrana. Vrana is seen as debilitating and scaring disorder, usually seen affecting the human being at any age. Well balanced nutrition plays an essential role in the wound healing.
