Iranian researchers have developed a bio-based method to extract and purify silk proteins—fibroin and sericin—using environmentally friendly techniques. These natural proteins, derived from silkworm cocoons, are known for their powerful healing properties and are now being prepared for use in medical, pharmaceutical, and cosmetic products. The achievement was reported by Mehr News Agency, a partner of TV BRICS.
Experts say the proteins were produced through green synthesis methods, which improve safety and cellular compatibility compared to traditional chemical techniques. The research team also created bio-based materials like hydroxyapatite, calcium oxide, and calcium hydroxide, which are widely used in tissue regeneration.
In preclinical trials, the researchers combined silk fibroin with bio-hydroxyapatite to treat joint injuries. When implanted into bone cavities in rabbits, the combination significantly sped up cartilage and bone regeneration. The results showed faster healing and better bone formation compared to untreated control groups.
What sets this method apart is the use of green synthesis, which avoids harmful chemicals. This makes the materials especially safe for sensitive uses such as wound care, implants, and medical sutures.
Beyond medicine, the researchers also pointed to other applications. Silk fibroin could be used in edible coatings to extend the shelf life of fruits and vegetables, or in absorbable surgical threads that naturally break down in the body.
Thanks to local production, these advanced biomaterials are already supporting several Iranian universities and research centers, providing them with affordable and effective tools for medical research and treatment.
