A team of scientists from the National University of Singapore (NUS) has engineered a magnetic hydrogel with the intent of expediting the recovery process for wounds related to diabetes, thereby aiming to reduce the frequency of limb amputations. When used alongside an external magnetic instrument, this gel activates skin cells, which has led to a threefold increase in healing speed in laboratory studies, compared to existing treatment modalities. The technology also offers potential applications for treating other complicated wounds, such as burns.
This unprecedented form of cell therapy enhances wound repair, improves the general health of the wound, and minimizes the probability of future recurrences.
People diagnosed with diabetes commonly face complications in natural wound healing, resulting in chronic wounds that often escalate into severe infections and may necessitate limb amputations.
To mitigate this significant healthcare issue worldwide, NUS researchers have introduced an innovative magnetic hydrogel engineered to quicken the wound recovery rate in diabetic individuals. This new methodology not only facilitates faster healing but also aims to reduce the chances of wound reoccurrence and subsequent limb amputations.
Each treatment procedure entails the utilization of a dressing that is saturated with a hydrogel laden with skin cells vital for healing as well as magnetic particles. An external wireless magnetic device is employed to stimulate the skin cells, thereby hastening the healing process. The optimal duration for the magnetic stimulation is estimated to be between one and two hours.
Laboratory examinations have confirmed that this therapy, when complemented by magnetic activation, speeds up the healing of diabetic wounds approximately three times faster than traditional methods. While the primary focus has been on treating diabetic foot ulcers, the technology may be adaptable for treating an array of complex wounds, including burns.
Assistant Professor Andy Tay spearheads the research team, consisting of scientists from the NUS Department of Biomedical Engineering, NUS College of Design and Engineering, and the NUS Institute for Health Innovation & Technology. According to him, “Standard dressings merely serve to inhibit the deterioration of the wound and necessitate regular changing, imposing a considerable burden on healthcare systems and causing inconvenience to patients.”
In stark contrast, this pioneering invention from NUS adopts a comprehensive, multi-faceted approach to wound recovery.
The technology addresses various key aspects of diabetic wound healing, such as managing elevated glucose levels, rejuvenating dormant skin cells, restoring impaired blood vessels, and fixing the damaged vascular network within the wound,” said Assistant Professor Tay.
The research findings have been published in the scientific journal, Advanced Materials, and were carried out in collaboration with scientists from the Agency for Science, Technology and Research, Nanyang Technological University, Sun Yat-sen University, and Wuhan University of Technology.

The Growing Challenge of Chronic Diabetic Wounds
Currently, over half a billion people around the globe are living with diabetes, and this number is anticipated to increase substantially. Thus, chronic diabetic wounds, particularly foot ulcers, represent a significant international healthcare dilemma.
Traditional approaches to treating these chronic wounds have proven to be inadequate, often leading to repeated healthcare complications and a high frequency of limb amputations.
According to statistics, between 9.1 and 26.1 million instances of diabetic foot ulcers are recorded globally every year, and approximately 15 to 25 percent of individuals with diabetes will likely develop a diabetic foot ulcer at some point in their lives. Notably, Singapore has one of the highest incidences of lower limb amputations due to diabetes, averaging about four cases per day.
Advancements in Active Wound Care
The magnetic hydrogel technology has demonstrated significant promise in advancing the treatment of complicated wounds beyond those related to diabetes, thus marking a paradigm shift in wound management practices.
Additional tests are being conducted to further enhance the efficacy of this magnetic hydrogel, and collaborations are in progress with clinical partners to evaluate the gel’s performance on diabetic human tissues.
“This represents a substantial advancement in active wound care, and our objective is to offer an efficient and convenient wound-healing solution that will better the outcomes for millions of people globally,” added Assistant Professor Tay.
Frequently Asked Questions (FAQs) about magnetic hydrogel for diabetic wound healing
What is the main innovation in the research conducted by the National University of Singapore?
The main innovation is a magnetic hydrogel developed to expedite the healing of diabetic wounds. This gel, when used in conjunction with an external magnetic device, accelerates skin cell activity and has shown to heal diabetic wounds three times faster than conventional methods.
Who are the main researchers behind this project?
The project is led by Assistant Professor Andy Tay, who is part of a team from the Department of Biomedical Engineering at the National University of Singapore’s College of Design and Engineering, as well as the NUS Institute for Health Innovation & Technology.

How does the magnetic hydrogel work?
The magnetic hydrogel contains skin cells and magnetic particles. It is applied to the wound via a pre-loaded bandage. An external magnetic device activates the skin cells and magnetic particles in the hydrogel, which stimulates accelerated wound healing. The ideal duration for magnetic stimulation is approximately one to two hours.
How effective is this treatment compared to traditional methods?
Lab tests have indicated that this treatment heals diabetic wounds about three times faster than conventional approaches. It also addresses multiple critical factors associated with diabetic wounds, such as elevated glucose levels and damaged blood vessels, improving overall wound health.
Can this magnetic hydrogel be used for other types of wounds?
Yes, while the primary focus has been on diabetic foot ulcers, the technology shows promise for treating a wide range of complex wounds, including burns.
What is the current status of this research?
The research has been published in the scientific journal Advanced Materials. A patent has been filed for this innovation, and more tests are being conducted to further refine the magnetic hydrogel’s effectiveness. There is also ongoing collaboration with a clinical partner to test the gel on diabetic human tissues.
What is the significance of this research for diabetic patients?
The research holds the promise of reducing the rates of wound recurrence and, consequently, the rates of limb amputations among diabetic patients. It also aims to provide an effective and convenient wound-healing solution for a significant global healthcare challenge.
Are there any plans for clinical trials?
The article indicates that the researchers are collaborating with a clinical partner to test the gel’s effectiveness using diabetic human tissues, suggesting that clinical trials may be in the planning stages.

I’ve been reading up on the issue of diabetic foot ulcers and the figures are scary. This could really be a lifesaver for many. Does it also work on older patients?
Wow, this is game-changing stuff right here. can’t believe they’ve found a way to speed up healing like this. Does anyone know when this could hit the market?
I’m floored! As someone who has a family member struggling with diabetes, this could be life changing. The science behind this is really something. Where can we read the full research paper?
this could actually be a revolution in healthcare. not just for diabetics but for any kind of complex wounds. Kudos to the NUS team.
Wait, so it’s like a bandage but it’s loaded with this gel? and you put a device on it? Sounds like something from a sci-fi movie. But if it works, it works!
Really excited bout this. Always good to see technological innovations that can have a real-world impact, especially in healthcare. Makes you wonder what else we’re close to discovering.
Is there any info on the cost? Seems great, but if it’s too expensive, then it’ll be out of reach for many people who actually need it.
