45S5 Bioglass-Derived Glass-Ceramic Scaffolds Containing Niobium Obtained by Ge...
Siqueira,Lilian de; Grenho,Liliana; Fernandes,Maria H.; Monteiro,Fernando J.; Trichês,Eliandra S.Scaffolds of bioglass derived from BG45S5 (45 wt% SiO2, 24.5 wt% CaO, 24.5 wt% Na2O and 6 wt% P2O5) containing 10 wt% niobium were prepared by gelcasting method. The scaffolds presented a 3D porous structure with interconnected and spherical pores (pore size range 100 μm to 500 μm) and high porosity (89%), similar to trabecular architecture of spongy bone. The compressive strength was 0.18 ± 0.03 MPa which is a...
Morphological, thermal and bioactivity evaluation of electrospun PCL/β-TCP fibe...
Siqueira,Lilian de; Passador,Fábio Roberto; Lobo,Anderson Oliveira; Trichês,Eliandra de SousaAbstract Electrospinning is a simple and low-cost way to fabricate fibers. Among the various polymers used in electrospinning, polycaprolactone (PCL) stands out due to its excellent biodegradability and biocompatibility. However, PCL has some limitations such as low bioactivity, hydrophobic surface, and long in vivo degradation. Calcium phosphate ceramics have been recognized as an attractive biomaterial. They ...
