The ReNew Biotechnology Limited developed “Biomimicking Photocrosslinkable Nanocomposite (BPN) bone grafts”, which mirror the structure of natural bone and are fabricated under simple and green, low-temperature and organic solvent-free conditions. The bone grafts can load and long-term release bioactive molecules, activate cell signalling pathways to simultaneously promote osteogenesis and angiogenesis, while providing optimal mechanical support to the injured area, expediting the bone-healing process.
