These mussels could save your life

As a native of the Normandy coast, I've long enjoyed “Moules frites” by the seaside without knowing about their remarkable benefits. Savoring them with a glass of white wine in the cool sea breeze, I never imagined how essential mussels could be to our progress.

Indeed, mussels are highly inspiring in biomimetic research. Their adhesive capabilities, natural water filtration, and purification systems inspire humans. Mussels are particularly studied in the development of new materials for naval engineering and marine architecture. However, it is in the medical field that their biomimetic properties will be most impressive for scientific advancement. A biomimetic bandage inspired by mussels could become the ultimate surgical solution to stop severe internal bleeding.

In South Korea, six researchers from POSTECH, Ewha Womans University and the College of Medicine at the Catholic University of Korea are behind this medical breakthrough. This biomimetic bandage is inspired by the natural adhesive used by mussels to cling to rocks. This synthetically reproduced adhesive has the ability to stick even in very moist environments, such as the human body. Then, researchers decided to combine this material with silkworm’s fibers, known for their resistance and healing properties. These synergistic elements promote blood coagulation and tissue regeneration. Therefore, this internal bandage offers an effective solution for treating internal hemorrhage more safely and effectively.

Nowadays, surgical gauze compresses are used to stop bleeding from internal wounds. Although, these compresses are not ecological and can be forgotten during an operation, leading to complications... In addition to its effectiveness in stopping bleeding, this bandage is biocompatible: which reduces the risk of allergic reactions or infections. What's more, its natural protein-based composition offers better integration with the body's tissues, promoting rapid healing and minimizing scarring.

This research opens up promising new prospects for the treatment of bleeding and the prevention of infections. Thanks to the use of proteins that are natural to the human body, this dressing offers a healthy, effective and sustainable solution. Professor Hyung Joon Cha, who heads the research group, is optimistic about the future applications of this agent in medicine and surgery, which is currently being tested on animals.

This medical breakthrough is just one example of the many nature-inspired innovations that are shaping our future. From textiles to transport and energy, biomimetic innovations promise a safer, more sustainable world for us all.
