29th March 2025: Researchers at the National Institute of Technology Rourkela (NITR) have developed a bioink that could revolutionize bone defect treatment. Led by Dr. Devendra Verma, the team has created a bioink using natural materials for 3D bioprinting of bone-like structures. This innovation addresses the challenges of traditional bone grafting and implants, offering a more efficient and personalized approach.
The bioink is made from chitosan, gelatin, and nanohydroxyapatite, which are biocompatible and closely resemble natural bone components. It remains in liquid form at room temperature but quickly gels at body temperature, allowing for direct application to injuries. This feature simplifies the treatment process and supports stem cell growth for bone regeneration.
This groundbreaking work, published in scientific journals, has led to a patent (No. 562791) and holds promise for use in reconstructive surgeries, especially for skull and facial bone repairs. The technology, funded by the Department of Health Research, Government of India, could significantly improve orthopedic treatments in the future.
