“…Furthermore, nanofibers with different and complex morphology, such as a porous, hollow, or core-shell structure, can be produced with these methods [ 39 , 51 ], expanding the use of these ceramic nanofibers in biomedical applications. Among the materials produced by these techniques, titania, calcium phosphate, alumina, zirconia, calcium silicate, silica, and bioactive glasses can be cited [ 23 , 45 , 48 , 50 , 52 , 53 , 54 , 55 , 56 , 57 ].…”
