The development of novel, multifunctional wound dressings is essential in the goal of achieving new therapies able to increase the quality of the treatment of patients suffering from insufficient wound healing, especially in the case of chronic and infected wounds. Based on the high social, economic and personal impact of skin wounds, ideal wound dressings able to actively protect the wounded skin and promote the healing process are in demand. Among other properties, modern wound dressings should be easy to produce (cost-effective) and should combine antibacterial with angiogenic properties in addition of being mechanically robust and pliable for easy application. Wound dressings, which can be used to deliver topically drugs or molecules, are of great interest as they can face the challenges leading to an effective wound healing process. Bioactive glasses (BGs) are a class of non-crystalline, inorganic materials able to release biologically active ions during implantation in the human body, which can induce specific cell responses such as accelerating haemostasis and angiogenesis. Research on BGs has mainly focused on their use in the field of bone replacing devices and bone tissue engineering. However, an increasing amount of studies is reporting promising results on the use of BGs in the regeneration of soft tissues and in wound healing. By designing new BG compositions with the capability to release ions that induce specific biological reactions, the applications of BGs are being further expanded in soft tissue repair. In this context, BGs have shown great potential for wound healing applications especially when BG compositions incorporating biologically active ions have been considered. Therefore, in the first part of this study, copper and/or zinc containing borosilicate and borate BGs were designed for wound healing applications. Copper was chosen to impart angiogenic properties and zinc to introduce antibacterial effects. The fabricated BGs were chemically and physically characterized and they showed ...
