Recreating Sea Silk from the Atrina pectinata Mollusk
On June 14 at 11:00 AM, a team of South Korean researchers from POSTECH, led by professors Dong Soo Hwang and Jimin Choi, successfully recreated sea silk from the Atrina pectinata mollusk. Their breakthrough reveals the secret behind the fiber's remarkable resistance to fading. The findings were published in the scientific journal Advanced Materials.
Historically, sea silk was made from the byssus threads of the Pinna nobilis mollusk, a species now critically endangered due to marine pollution. In response, the European Union has imposed a complete ban on harvesting Pinna nobilis. To address this challenge, the Korean scientists turned to Atrina pectinata, a mollusk widely farmed in local coastal waters for the food industry. The byssus threads of Atrina pectinata are nearly identical in physical and chemical properties to their Mediterranean counterpart, opening up new possibilities for reviving sea silk production.
Discovery and Its Significance
The researchers also discovered that the color of sea silk results from a phenomenon known as structural coloration. The microscopic, layered spherical proteins responsible for the silk's unique appearance have been named 'photonin.' This finding could mark a major step forward in further research and applications of sea silk across various industries.
Beyond reviving sea silk production, this discovery holds potential for advancing new technologies in the textile industry. It also highlights the importance of protecting marine species and ecosystems, as the use of sustainable resources can help alleviate pressure on endangered species. The prospects of utilizing Atrina pectinata could not only restore a traditional craft but also shape the future of biomaterials research.
