Hot dog‐like scaffolds are an excellent carrier for drug and protein. The drug Ica and protein BSA loading and release properties of the HD‐AKT. a) The Ica loading efficiency, and b) the loading capacity of traditional solid struts scaffolds(S‐AKT), H‐AKT, and different kinds of HD‐AKT. c) Thermogravimetric analysis of the scaffolds after loading the Ica. d) The Ica release of different kinds of scaffolds after loading Ica (S‐AKT/Ica, H‐AKT/Ica, HD‐20AKT/Ica, HD‐30AKT/Ica, HD‐40AKT/Ica, and HD‐50AKT/Ica). e) The BSA loading efficiency. f) The BSA release of the scaffolds. g–i) SEM images of the hot dog rod of scaffolds g) after 90 d Ica release. h) Surface images and i) the cross‐section image show lots of mineralized hierarchical structures on the surface of hot dog rod of scaffolds. Compared with the S‐AKT and H‐AKT, the HD‐AKT have higher loading efficiency and capacity. Meantime, HD‐AKT possess longer Ica/BSA release time.
