Recently, a research team from the University of Granada in Spain has developed a low-cost artificial cornea using fish scales, bringing new hope to patients with corneal blindness. The core raw material behind this innovation — fish scale gelatin rich in Type I collagen — is the core business of Audima highlighting the potential of fish scale deep processing and Audima’s technological foresight.
The research team from Spain focused on the fiber structure of Type I collagen in fish scales, which matches that of human corneas. Through special processes, it can be made into highly compatible corneal implants, solving the pain points of donor shortage and high cost.
Fish scale gelatin is made from high-quality fish scales. It retains the activity of Type I collagen and has the advantages of high biocompatibility and low allergenicity. It is not only suitable for the food and cosmetics industries, but also has broad prospects in the biomedical field, providing reliable raw material support for cutting-edge technologies such as artificial corneas.
The research results were published in the international SCI journal Materials & Design, with the following paper source index:

The paper emphasizes that fish scale biomaterials have the core advantages of low cost, wide source and good biocompatibility, which are exactly the core competitiveness of Audima’s fish scale gelatin. Adhering to the concept of "resource recycling and high-value utilization", Audima converts aquatic by-products into high-value-added products, conforms to the green and low-carbon trend, and provides natural and safe raw material solutions for various fields.
With the development of the biomedical field, the application boundary of fish scale gelatin is constantly expanding. Audima will deepen R&D, optimize production processes, provide high-quality fish scale gelatin products, explore its in-depth application in the biomedical field, help the implementation of cutting-edge technologies, and empower resource recycling and protect human health with science and technology.
