Scientists from the University of Nottingham have spent five years researching a technology that can chemically produce spider silk for drug delivery, regenerative medicine and wound healing. The research team demonstrated for the first time how "click chemistry" connects molecules such as antibiotics , fluorescent dyes, and artificially made spider silks with Bacillus bacteria . The selected molecules can be "clicked" before being converted into fibers, or after forming fibers, that is, the process is controllable.

Recently, the research team has begun to connect the artificial spider silk with a variety of small molecules, using levofloxacin to "dress" the spider silk, and release it slowly for at least 5 days. The research team is responsible for the process: "Our technology can quickly generate biocompatibility, especially for tissue engineering and biotechnology."

Spider silk is very strong, both biocompatible and biodegradable, and the spider silk is made of protein, so the human body will not react strongly to it, nor will it be inflamed or allergic. Therefore, it is high. The quality of spider silk is the focus of the research team's current work.

The research team said: "Our technology can be used to treat chronic wounds, such as diabetic ulcers, using our technology to ensure that wounds are not infected within a few months."

In fact, as early as centuries ago, people have already understood the benefits of spider silk. In ancient Greece, ancient Rome also used spider webs to stop bleeding for wounded people. It is said that the wounded will first clean the wound with vinegar and honey, and then use spider webs. Bandaging.

The research team leader said: "The current research is only the beginning, we will continue to study new spider silk materials and study its broader role."
