Researchers of University of Tehran, supported by Iran National Science Foundation, have made single filament biodegradable surgical suture which can be dissolved inside the body without any side effects.

According to an ISCA report, the project executor Babak Kaffashi stated that monofilament biodegradable surgical suture are mostly imported to the country but we have enough potential to produce it ourselves to prevent outflow of currency from the country.

In medicine, biodegradable polymers offer great potential for controlled drug delivery and wound management (e.g., adhesives, sutures, and surgical meshes), for orthopedic devices (screws, pins, and rods), and for dental applications (filler after a tooth extraction) and tissue engineering, just to name the most important.

The application of biodegradable synthetic polymers started several decades ago, and since then it has been the focus of much research. This is because the requirements are quite complex: the polymer must be biocompatible, not to evoke an inflammatory response, and must have suitable mechanical and processing characteristics.

Furthermore, the degradation products cannot be harmful and must be readily resorbed or excreted. For these reasons, it is important to test each material adequately before use in the human body, not only in vitro but also in vivo.
