Bioinspired self-assembly nanotechnology assembles building blocks into nanostructures without external forces by mimicking highly optimized molecular self-assembly rules found in nature, such as nucleic acid, protein, and peptide self-assembly. The features that emerge from this process include molecular recognition, hierarchical assembly, and dynamic adaptability, endowing the resulting nanostructures with excellent physicochemical properties. These characteristics allow different functional materials with different architectures to be designed and fabricated. Bioinspired self-assembled nanostructures have attracted a lot of interest in regenerative medicine because of their remarkable biocompatibility, biodegradability, and biological activity. Nanomaterials created through this technology can efficiently and selectively perform complex biological functions, showing great potential as scaffolds, drug carriers, and cell engineering materials in regenerative medicine.
