Electrophoretic deposition of spray-dried Sr-containing mesoporous bioactive glass spheres on glass–ceramic scaffolds for bone tissue regeneration

Bioactive layers based on black glasses on titanium substrates

“…This fact draws the attention to the composite materials containing bioceramic and bioglass in the form of layers or particles. Using methods such as laser cladding, sol‐gel, dip coating, electrophoretic deposition it is possible to obtain biomedical implants and scaffold not only biocompatible but also may mimic and stimulate new bone formation . Dense and porous composites might be of the glass‐ceramic, ceramic‐polymeric and ceramic‐metallic type .…”

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

“…The polymeric foam showed a highly oriented porous structure of tubular macropores (>100 µm in diameter) interconnected with small pores within 20-30 µm. 90 Bioactive glass coatings on porous silicate glass-ceramics were also produced by simple dipping in a sol or glass slurry, but this approach provided less control on the coating characteristics (eg, thickness, homogeneity, reproducibility) compared to EPD. 87 It is worth noting that EPD has also been successfully used to deposit a layer of bioactive glass on the struts of mechanically strong but almost-inert ceramic scaffolds.…”

“…88 In this way, multifunctional properties can be imparted to the porous substrate, namely apatite-forming ability 89 and controlled release of therapeutic agents (eg, strontium ions that can reduce bone resorption in osteoporotic patients). 90 Bioactive glass coatings on porous silicate glass-ceramics were also produced by simple dipping in a sol or glass slurry, but this approach provided less control on the coating characteristics (eg, thickness, homogeneity, reproducibility) compared to EPD. 91 Following the same rationale, Yu et al 92 recently deposited a sol-gel bioactive glass coating onto wood-derived carbon scaffolds ( Figure 7B).…”

Guest editors’ preface

“…Such composite systems are also featured in other papers within this special section, for example bioactive glass-biopolymer composites [24][25][26], hybrids [27], Ag-coated bioactive glass scaffolds [28] and antibiotic-releasing biopolymer-bioactive glass films [29]. Bioactive glasses are considered as coating materials for different substrates to provide surface bioactivity, and this aspect is covered in papers describing different coating methods involving bioactive glasses on a variety of substrates [30][31][32][33][34]. Other publications deal with innovative technologies to produce bioactive phosphate glass fibers [35], 3D scaffolds based on additive manufacturing methods [36], multifunctional ferrimagnetic [37] and bioinspired bioactive glass-ceramics [38] as well as novel polyphenol-functionalized bioactive glasses [39].…”
