Scientists have found that silk can be used in bone surgery to "melt" in the human body, eliminating the need for a second surgery to remove it. In addition, silk has natural advantages such as antibacterial and wound healing. The research results have been published in the Natural Communication.
Silk not only melts on its own, but also has more benefits. Samuel Lin, one of the authors of the paper, Boston Beth Isrell Deacon Medical Center, said: "Unlike metals, silk protein is similar in composition and bone. Silk is extremely strong and can be used in extreme environments such as high temperatures. Maintaining a stable structure. They are also easy to disinfect," said David Kaplan, a research leader at Tufts University. "One of the great advantages of silk is that it stabilizes and releases bioactive ingredients. So, made with silk. The screws and splints actually have an antibacterial effect that prevents infection; it also releases drugs that promote bone growth and wound healing."
In the experiment, the researchers implanted 28 screws made of silk into 6 mice, all of which were successful. Silk is easy to obtain and durable, and the prospects for making splints and screws are limitless.
In the face of patients with fractures, traditional therapies use metal screws and splints to fix the damaged bones. After the patient is cured, surgery is required to remove them. Traditional metal materials are stiff and there is a risk of infection.
