Recent data have reported that the burden of infections related to antibiotic-resistant bacteria in the European Union and European Economic Area (EEA) can be estimated as the cumulative burden of tuberculosis, influenza, and human immunodeficiency virus (HIV). In wound management, the control of infections represents a crucial issue and a multi-billion dollar industry worldwide. For diabetic wounds ulcers, in particular, infections are related to the majority of amputations in diabetic patients, which today represent an increasing number of the elderly. The greatest barrier to healing is represented by the biofilm, an organized consortium of bacteria encapsulated in a self-produced extracellular polymeric substance with high resistance to conventional antimicrobial therapies. There is an urgent need for novel anti-biofilm strategies and novel antimicrobial agents and, in this scenario, silver nanotechnology has received tremendous attention in recent years in therapeutically enhanced healthcare. Due to its intrinsic therapeutic properties and the broad-spectrum antimicrobial efficacy, silver nanoparticles have opened new horizons towards novel approaches in the control of infections in wound healing. This review aims at providing the reader with an overview of the most recent progress in silver nanotechnology, with a special focus on the role of silver in the wound healing process.

Abstract Wound healing is a complex process with many interdependent pathophysiological and immunological mediators to restore the cellular integrity of damaged tissue. Cutaneous wound healing is the repair response to a multitude of pathologies induced by trauma, surgery, and burn leading to the restoration and functionality of the compromised cells. Many different methods have been employed to treat acute and chronic wounds, such as antimicrobial therapy, as most wounds are susceptible to infection from microbes and are difficult to treat. However, many antimicrobial agents have become ineffective in wound treatment due to the emergence of multiple drug-resistant bacteria, and failures in current wound treatment methods have been widely reported. For this reason, alternative therapies have been sought, one of which is the use of honey as a wound treatment agent. The use of honey has recently gained clinical popularity for possible use in wound treatment and regenerative medicine. With this high demand, a better delivery and application procedure is required, as well as research aiming at its bioactivity. Honey is a safe natural substance, effective in the inhibition of bacterial growth and the treatment of a broad range of wound types, including burns, scratches, diabetic boils (Skin abscesses associated with diabetic), malignancies, leprosy, fistulas, leg ulcers, traumatic boils, cervical and varicose ulcers, amputation, burst abdominal wounds, septic and surgical wounds, cracked nipples, and wounds in the abdominal wall. Honey comprises a wide variety of active compounds, including flavonoids, phenolic acid, organic acids, enzymes, and vitamins, that may act to improve the wound healing process. Tissue-engineered scaffolds have recently attracted a great deal of attention, and various scaffold fabrication techniques are being researched. Some incorporate honey to improve their delivery during wound treatment. Hence, the aim of this review is to summarize recent studies on the wound healing properties of honey.

The Right

Today, various commercial dressings have been developed and introduced to the market. The diversity makes it difficult for the nurse to choose the right type. Although the most important reason to use a wound dress is to protect the wound from infection and prevent infection, but in fact, the main purpose of using these materials is to speed up the wound healing process. Traumatic injuries result in an epithelial wound that disrupts the continuity of the skin surface. These differences reveal as abrasions, punctures, and injuries. Wounds are divided into two types; the skin is either cut or ruptured, including deep wounds and bruises, or surface wounds. Expedited wound healing has been considered since the archaic era of human civilization, with the earliest reported case from the Ancient Egyptians. Wound lesions in mummified humans were observed to be cover with animal skin, with signs of (primary/secondary) wound healing present. A "new wound dressing" is an advanced wound dress used in wound management as biocompatible and biodegradable biomaterials that heal wounds and burns. In the past, it was believed that dry wounds had expedited healing and wet wounds have been found to promote using re-epithelization and result in reduced scar formation. Wounds can be treated using various types of natural polymers and materials. Also, techniques like electrospinning and freeze-drying techniques can be used for the fabrication of standard wound dress. These wounds are associated with bandages, inflammation, bleeding, pain, and pus. In this work, we consider various types of wounds and techniques to treat the wound. Susceptibility to these areas, due to special symptoms for each of them. Products like hydrogels, hydrocolloids, films, sponges, and nano-fiber polymeric materials are used to promote healing. In this review, we examine the ideal products for the treatment of wounds in diabetic patients.

Healing Wounds

A wound is damage to the typical anatomic structure. Wound healing is an immediate therapeutic response to injury. It is a creation of the combined response of some cell types towards injury. Wound healing takes place by a sequence of molecular events which cooperate to fix tissue integrity and cell work. In typical healthy individual under ordinary conditions, these physiological events take place smoothly. Though sometimes, these molecular events are arrested, this brings about in struggle to heal. There is an assortment of approaches for the way toward managing and controlling both acute injuries (acute wounds) and ceaseless non-mending wounds (chronic non-healing wounds). The principal objective of these two cases is to achieve better-wound healing. Ideal formulations of wound healing should not only enhance the healing process but also reduce pain, infection and loss of electrolytes, proteins and liquids from the injury. A broad scope of items typically introduced with target various parts of the wound healing process depends on numerous types of wounds and novel polymers utilised for the conveyance of medications to both acute and ceaseless injuries. These include alginate, hydrocolloids, hydrofibers, polyurethane, and hydrogels. This article gives particular importance to different novel approaches in the management of wound healing. This review draws out the data and hopes to provide understanding into traditional, current and imminent techniques and methods for wound management.

Delayed Wound Healing

Wound care is a major biomedical field that is challenging due to the delayed wound healing process. Some factors are responsible for delayed wound healing such as malnutrition, poor oxygen flow, smoking, diseases (such as diabetes and cancer), microbial infections, etc. The currently used wound dressings suffer from various limitations, including poor antimicrobial activity, etc. Wound dressings that are formulated from biopolymers (e.g., cellulose, chitin, gelatin, chitosan, etc.) demonstrate interesting properties, such as good biocompatibility, non-toxicity, biodegradability, and attractive antimicrobial activity. Although biopolymer-based wound dressings display the aforementioned excellent features, they possess poor mechanical properties. Gelatin, a biopolymer has excellent biocompatibility, hemostatic property, reduced cytotoxicity, low antigenicity, and promotes cellular attachment and growth. However, it suffers from poor mechanical properties and antimicrobial activity. It is crosslinked with other polymers to enhance its mechanical properties. Furthermore, the incorporation of antimicrobial agents into gelatin-based wound dressings enhance their antimicrobial activity in vitro and in vivo. This review is focused on the development of hybrid wound dressings from a combination of gelatin and other polymers with good biological, mechanical, and physicochemical features which are appropriate for ideal wound dressings. Gelatin-based wound dressings are promising scaffolds for the treatment of infected, exuding, and bleeding wounds. This review article reports gelatin-based wound dressings which were developed between 2016 and 2021.

Skin regeneration after an injury is very vital, but this process can be impeded by several factors. Regenerative medicine is a developing biomedical field with the potential to decrease the need for an organ transplant. Wound management is challenging, particularly for chronic injuries, despite the availability of various types of wound dressing scaffolds in the market. Some of the wound dressings that are in clinical practice have various drawbacks such as poor antibacterial and antioxidant efficacy, poor mechanical properties, inability to absorb excess wound exudates, require frequent change of dressing and fails to offer a suitable moist environment to accelerate the wound healing process. Collagen is a biopolymer and a major constituent of the extracellular matrix (ECM), making it an interesting polymer for the development of wound dressings. Collagen-based nanofibers have demonstrated interesting properties that are advantageous both in the arena of skin regeneration and wound dressings, such as low antigenicity, good biocompatibility, hemostatic properties, capability to promote cellular proliferation and adhesion, and non-toxicity. Hence, this review will discuss the outcomes of collagen-based nanofibers reported from the series of preclinical trials of skin regeneration and wound healing.

Chronic Ulcers

Chronic ulcers are a leading cause of morbidity in diabetic patients. Diabetes is associated with major changes in the wound microenvironment and disruption of normal wound healing process, characterized by a prolonged inflammatory phase with elevated levels of wound proteases and increased degradation of extracellular matrix (ECM) components [1]. This impedes wound healing due to a lack of provisional matrix, impaired recruitment and survival of endothelial (EC) and endothelial precursor (EPC) cells, and insufficient neovascularization, resulting in delayed healing. Therefore, strategies focused on restoring the diabetic wound microenvironment by decreasing ECM degradation and promoting neovascularization are promising for development of new therapies to treat chronic diabetic ulcers.

Wound healing has been intensely studied in order to develop an “ideal” technique that achieves expeditious recovery and reduces scarring to the minimum, thus ensuring function preservation. The classic approach to wound management is represented by topical treatments, such as antibacterial or colloidal agents, in order to prevent infection and promote a proper wound-healing process. Nanotechnology studies submicroscopic particles (maximum diameter of 100 nm), as well as correlated phenomena. Metal nanoparticles (e.g., silver, gold, zinc) are increasingly being used in dermatology, due to their beneficial effect on accelerating wound healing, as well as treating and preventing bacterial infections. Other benefits include: ease of use, less frequent dressing changes and a constantly moist wound environment. This review highlights recent findings regarding nanoparticle application in wound management.
