Tailoring the structural evolution, in vitro bioactivity, and gastrointestinal cell cytocompatibility of sol–gel-derived Bi(III)-doped bioactive glasses: The role of bismuth precursors
Bismuth(III)-doped 13–93 silicate bioactive glass powders were synthesized via a sol–gel route with Bi₂O₃ contents ranging from 0.1 to 5 wt% using two different precursors, BiCl₃ and Bi(NO₃)₃.5H2O. Structural characterization by X-ray diffraction and FTIR confirmed the predominantly amorphous nature of the glasses and...
