Effect of ion substitution on properties of bioactive glasses: A review

Solid-State 87Sr NMR Spectroscopy at Natural Abundance and High Magnetic Field Strength

“…Note that 87 Sr has I = 9/2; the single-crystal NMR spectrum should consist of nine spectroscopic transitions for each site (not shown due to the breadth of the outer satellite transitions, likely due to crystal imperfections). Examples of magnetic nonequivalence such as this have been discussed previously, for example, the 133 Cs NMR spectrum of CsCd(SCN) 3 reported by Kroeker et al in 1997. 75 The 87 Sr NMR spectrum of solid, powdered celestine is shown in Figure S2.…”

Processing methods for making porous bioactive glass‐based scaffolds—A state‐of‐the‐art review

“…19 3. 10,[23][24][25][26] Combining different kinds of materials is a valuable strategy to obtain new materials with enhanced properties, resulting from the characteristics of the starting raw materials. 22 In addition to the former oxides and basic modifiers (eg, CaO, Na 2 O), a lot of other metallic doping elements can be added to the composition to tune the bioactivity and give peculiar extra-functionalities to the glasses, such as silver (antibacterial effect), copper (angiogenesis), and strontium (anti-osteoporotic effect).…”

Gallic acid grafting to a ferrimagnetic bioactive glass-ceramic

“…The introduction of different modifying oxides allows the release of ions with specific stimulation ability for cells: Ca ++ for osteoblast proliferation, differentiation, and mineralization, Mg ++ for cellular adhesion and bone formation, Zn ++ , Cu ++ , and Ag + for an antibacterial action, to cite only some examples [4,5]. The effect of different ions on the bone bonding and antibacterial properties of bioactive glasses have recently been reviewed [6,7]. It has been observed that bioactive glasses and their dissolution products can stimulate bone regeneration by affecting some cellular functions at the genetic level [8].…”
