Chronic wounds that do not heal pose a major problem for patients' quality of life and impact the costs of the healthcare system. The pathophysiological mechanisms that impede wound healing are usually multifactorial and related to the patient's general health and diet, wound bed vascularity, and coexisting infection/colonization. Bacterial infection is one of the major problems that can cause wounds to stall and become chronic. Successful wound healing often depends on antibiotic therapy lasting weeks or months, which is problematic given the rise of multidrug-resistant bacteria. and is urgently needed to support the healing of acutely infected wounds. Since nitric oxide (NO) kills bacteria through various mechanisms, it may be an excellent alternative to antibiotic therapy as bacteria show no tendency to develop resistance to NO as a therapeutic agent. This article reports the development of NO-releasing electrospun membranes fabricated from polycaprolactone (PCL)/gelatin blends and optimized to reduce bacterial infection. The membrane NO payload was directly related to the number of amines (and thus the amount of gelatin) in the mixture. The higher the NO payload, the higher the level of antibacterial effect. No cytotoxicity was observed with electrospun membranes, and an in vitro wound closure test showed closure within 16 hours. The results presented here clearly demonstrate that these NO-releasing electrospun membranes are promising as wound dressings due to their antibacterial activity and biocompatibility. The development of nitric oxide nanoparticles represents a promising new development in this therapeutic area. NO nanoparticles combine the robust, malleable, and porous properties of silane-based sol-gel matrices with the thermal properties of sugar glass. It is a new composite material that combines reducibility potential. The payload and release rate from NO-releasing membranes were analyzed using a Sievers 280i chemiluminescence nitric oxide analyzer (NOA280i, GE). Membranes (10 × 10 mm2) were placed in a three-necked round-bottom flask and immersed in 5 mL of acetate buffer (pH 4), phosphate-buffered saline (PBS; pH 7.4), or ambient temperature cell culture medium. NO payloads from different NO-releasing membranes were determined using a chemiluminescence nitric oxide analyzer at pH 4 (acetate buffer) and pH 7.4 (PBS). Nitric oxide (NO) plays an important role in maintaining and regulating the integrity of the skin and its environment. Impaired NO production has been implicated in the pathogenesis of various skin diseases and points to future therapeutic directions. In an era of increasing resistance to available antibiotics and inadequate new drug development, NO holds promise as a promising broad-spectrum antibiotic with a low potential for resistance development. There is strong evidence that NO-releasing materials can serve as new and unique antibacterial agents at a time when current antibiotics are being confounded by increasingly resistant microorganisms. We review the multiple functions that NO plays in skin physiology, focusing on its antibacterial capacity and present evidence of its potential cosmetic utility. Nearly all members of the skin cell population express nitric oxide synthase (NOS), which allows them to generate NO and carry out essential physiological processes. This cell body includes keratinocytes, endothelial cells, fibroblasts, melanocytes, adipocytes, Langerhans cells, neutrophils, and macrophages. Due to the widespread distribution of NO producers in the skin, the molecules are involved in important skin physiological processes such as protective barrier formation and antimicrobial defense, establishment and maintenance of blood flow, melanogenesis and erythema in response to exposure to UV light.
