This review discusses the importance of nitric oxide and hydrogen sulfide in wound healing applications, as well as the challenges in designing effective delivery systems. It introduces different types of new releasing carriers to facilitate the application of these molecules in clinical practice.
Nitric oxide (NO) and hydrogen sulfide (H2S) have been recognized as important signalling molecules involved in multiple physiological functions, including wound healing. Their exogenous delivery has been established as a new route for therapies, being the topical application the nearest to commercialization. Nevertheless, the gaseous nature of these therapeutic agents and their toxicity at high levels imply additional challenges in the design of effective delivery systems, including the tailoring of their morphology and surface chemistry to get controllable release kinetics and suitable lifetimes. This review highlights the increasing interest in the use of these gases in wound healing applications by presenting the various potential strategies in which NO and/or H2S are the main therapeutic agents, with focus on their conceptual design, release behaviour and therapeutic performance. These strategies comprise the application of several types of nanoparticles, polymers, porous materials, and composites as new releasing carriers of NO and H2S, with characteristics that will facilitate the application of these molecules in the clinical practice.
