The main routes of SMA application for maintaining bone homeostasis. Two major routes of SMA applications are used for treating bone-related diseases by ameliorating bone homeostasis: a SMA-based drugs and b SMA-based biomaterials: SMA-based drugs, including drugs used for treating bone diseases and drugs for other diseases that show positive effects on bone homeostasis. SMA-based biomaterials include biomaterials on which SMAs have been physically loaded (for example, sponge-inspired sulfonated polyetheretherketone loaded with polydopamine-protected osthole nanoparticles and berberine;52 liposome carriers of desferrioxamine53) and biomaterials with chemical engrafting of SMAs (for example, polydimethylsiloxane surface with histidine- and leucine-conjugated (3-aminopropyl)-triethoxysilane;56 piperazine-based polyurethane-urea scaffolds58)
