Nanofiber scaffold for bone tissue engineering: Mechanism, challenge and future prospect

Figure 1 Biomedical and clinical application of nanofiber scaffold. With three-dimensional printing, electrospinning and other technologies as the core preparation process, nanofiber scaffolds radiate in many fields: Constructing bionic microenvironment in tissue engineering and regenerative medicine to repair defects. As a drug delivery system, accurate drug delivery; empower medical devices, prostheses and orthotics to achieve functional adaptation; power-assisted surgical instruments and guide plates to improve operating accuracy; used for radiotherapy equipment and phantom to optimize radiotherapy scheme; training models and simulators can also be developed to assist medical teaching and training, showing its multiple values in biomedical clinical scenes in an all-round way and providing material support for cross-disciplinary medical innovation.
