Scientists from Ateneo de Manila University are exploring the potential of using milkfish skin (Chanos chanos), locally known as bangus, as a cost-effective alternative for treating burns and skin injuries. This study builds on previous research that highlighted the wound-healing properties of tilapia skin, which is rich in Type 1 collagen. While tilapia skin has received attention in medical applications, the use of milkfish skin for wound care remains underexplored, despite the fish's widespread cultivation in the Philippines.
The Study Process
The researchers collected fresh skin samples from both tilapia and milkfish at a local market in Quezon City. These skins were descaled, rinsed in saltwater, and cut into strips. Some samples were sterilized with a solution of silver nanoparticles (AgNP), while others were left untreated as control samples. The goal was to assess whether the sterilization process could reduce microbial contamination without damaging the collagen structure, essential for the skin’s wound-healing properties.
The study found that AgNP sterilization effectively inhibited bacterial and fungal growth on both fish skin types, without compromising their structural integrity. This suggests that both tilapia and milkfish skins are suitable for use as wound dressings, potentially offering a safe and sustainable option for medical applications.
Implications for Sustainable Medical Materials
Milkfish skin presents an opportunity to develop a locally sourced, eco-friendly material for wound care. With the Philippines being a major producer of milkfish, this resource could become a low-cost alternative to synthetic bandages. The study highlights the potential of fish skin grafting, especially in regions where fish farming is prevalent and access to medical supplies may be limited.
According to the Bureau of Fisheries and Aquatic Resources' roadmap for the country's milkfish industry, the government targets an increased production of 1 billion milkfish fry by 2040. This growth could further solidify milkfish skin as a sustainable, cost-effective material for wound care.
