TL;DR

Scientists found that tiny bits of magnesium could help heal stubborn wounds that won't normally heal by fighting infection and reducing swelling, but we still need to do more testing before doctors can actually use it on patients because we don't fully understand how to safely control how fast the magnesium breaks down in the body.

Key Finding

Magnesium-based nanomaterials show significant promise in preclinical (laboratory and animal) studies for chronic wound healing through multiple mechanisms, but clinical translation is currently limited by safety concerns, lack of standardized testing methods, and insufficient human trial data.

Summary

This review examined how magnesium-based nanomaterials (tiny engineered materials made from magnesium) might help heal chronic wounds that don't heal normally. Laboratory and animal studies show these materials may reduce inflammation, promote new blood vessel growth, kill bacteria, and help tissue repair. However, most evidence is still in early research stages, and several safety and technical challenges—like controlling how fast the magnesium breaks down and managing hydrogen gas production—need to be solved before these materials can be tested in patients.

Practical Takeaway

While magnesium-based wound treatments are an active area of research with encouraging early results, they remain experimental and have not yet been proven safe or effective in humans. Anyone interested in emerging wound therapies should wait for rigorous clinical trials before considering these approaches, as the review emphasizes that current evidence is primarily from laboratory settings and that significant technical and safety challenges still need to be addressed.

Abstract

Chronic wounds remain a severe clinical challenge worldwide due to persistent inflammation, impaired tissue regeneration, and refractory infection control. Recently, magnesium-based materials have garnered tremendous attention for chronic wound healing owing to their exceptional biocompatibility, biodegradability, and multifaceted biological functions in remodeling the wound immune microenvironment. Well-established preclinical evidence demonstrates that magnesium and its derivatives facilitate chronic wound repair by regulating inflammatory responses, promoting angiogenesis, enhancing cellular proliferation and migration, and exerting antibacterial effects, thus constructing a favorable microenvironment for tissue regeneration. Emerging (though still partly speculative) findings suggest that degradation products of magnesium, particularly Mg2⁺ ions, play a central role in directing immune cell polarization, optimizing endothelial cell activity, and alleviating oxidative stress. Magnesium-based inorganic materials, nanostructured systems, and hybrid platforms integrated with hydrogels or other bioactive components also exhibit outstanding preclinical therapeutic potential. It is important to note that the vast majority of current evidence remains at the preclinical stage, and any interpretation of translational readiness should be made with caution. However, the clinical translation of these materials is still severely restricted by multiple bottlenecks: the lack of precise control over magnesium degradation and Mg2⁺ release kinetics, safety risks arising from local pH elevation and hydrogen gas generation, deficient long-term toxicological data, and the absence of standardized evaluation systems for magnesium-based wound dressings. Future research should prioritize the development of tunable and stimuli-responsive delivery systems, deepening mechanistic insights into magnesium-mediated immunomodulation, and incorporating advanced manufacturing technologies to realize personalized therapeutic strategies. Rigorous biosafety evaluations and clinically relevant preclinical models are also imperative. In conclusion, magnesium-based materials stand as a highly promising and versatile strategy for chronic wound repair, holding great potential to be developed as multifunctional platforms that integrate antibacterial, immunoregulatory, and tissue-regenerative properties for clinical translational applications.
