Abstract
A highly bioactive glass solvBG76 in a binary system 76SiO2-24CaO (wt%) was prepared following a solvothermal path of the synthesis. The facile synthesis, in terms of the steps and reagents needed, enabled the achievement of a mesoporous material. Many factors such as nano-size (<50 nm), different morphology (non-spherical), use of an unconventional network modifier (calcium hydroxide) during the synthesis, a structure free of crystalline impurities, and textural properties greatly enhanced the kinetic deposition process of hydroxyapatite (HA) when contacting with physiological fluids. The formation of a HA layer on the glass was analyzed by various techniques, namely XRD, IR-ATR, Raman, XPS, EDS analyses, SEM, and HR-TEM imaging. The results obtained were compared to the 45S5 glass tested as a reference biomaterial as well as 70S30C-a glass with similar size and composition to reported solvBG76 but obtained by the conventional sol-gel method. For the first time, superior apatite-mineralization ability in less than 1 h in a physiological-like buffer was achieved. This unique bioactivity is accompanied by biocompatibility and hemocompatibility, which was indicated by a set of various assays in human dermal fibroblasts and MC3T3 mouse osteoblast precursor cells, as well as hemolytic activity determination.

Abstract
This work is devoted to the development of non-lithographic template methods of synthesis. These methods have a significant advantage in terms of structure formation: there is no need to design and produce masks, which greatly simplifies the process, and more of them can work with nonplanar substrates. The purpose of this study was to reveal the conditions for the synthesis of titanium dioxide xerogel films of different topologies as well as to develop a technique for non-lithographic template electrochemical synthesis of micron metal particles arrays and to study the structure of the resulting coatings. The films were deposited on the surface of substrates via dip coating. Specific topology of the films was achieved by template sol-gel synthesis. Their structures were analyzed by SEM and XRD. Template synthesis of metal micro particles were realized by pulsed electrochemical deposition of metals into the perforations of xerogel films. Obtained materials were analyzed by SEM and XRD; the element distribution on the surface was determined by the EDS detector of SEM. Based on the analysis results, we suggest the mechanisms of formation of the xerogel topology and proved the efficiency of pulsed electrodeposition for template synthesis of micron particles arrays.

Abstract
The bone extracellular matrix (ECM) is a composite scaffold having inorganic hydroxyapatite and organic collagen fibers. Synthetic bone repair scaffolds that mimic the chemical composition of the native ECM and capable of delivering therapeutics are beneficial. In this study, we prepared intrinsically fluorescent organic-inorganic hybrid microparticle biomaterials by sol-gel process. Unlike the conventional Stöber process which requires an alkaline condition for microparticle formation, an acidic condition in the presence of a biodegradable poly(ester amide) (PEA) polymer was used to prepare silica and tertiary bioactive glass hybrids. During their preparation, one or two model drugs were loaded in the microparticles. Our results showed that a gelation temperature between 40 °C-60 °C and the inclusion of PEA were critical for microparticle formation. Unexpectedly, the hybrid microparticles were fluorescent with tunable emission by changing the excitation wavelengths ranging from 300 to 565 nm for potential multiplex imaging. Gene expression studies showed that the hybrid materials induce osteogenic differentiation of 10T1/2 cells without adding exogenous biochemical factors. The bioactivity of the inorganic phase and the dual drug release from homogenous, biodegradable, biocompatible, osteoinductive, and intrinsically fluorescent microparticles may offer a unique platform for bone regeneration and therapy.

Abstract
This study aimed to assess the mechanical and biological properties of bioactive glass (BG) coating on titanium (Ti). Bioinert Ti substrates were coated by BG to induce bioactivity to the surface. The sol-gel derived BG 58S sol was successfully prepared and coated on the abraded and blasted Ti surface using the sol-dip method. The characterization and cell study for all substrates' surface was carried out. Adhesion test confirmed that a firmly adhered BG coating layer was formed on the abraded and blasted Ti. The measured bonding strength between the coating and the blasted Ti substrate was the highest among all samples, which was 41.03±2.31 MPa. In-vitro cell viability and alkaline phosphatase activity (ALP) tests results also showed that BG coating on the Ti substrate improved the biological properties of the surface. The BG sol-dip coating method could be used to fabricate Ti substrate with a bioactive surface.

Abstract
The past few decades have seen the development of new bone cancer therapies, triggered by the discovery of new biomaterials. When the tumoral area is small and accessible, the common clinical treatment implies the tumor mass removal followed by bone reconstruction or consolidation with a bioceramic or a metallic scaffold. Even though the treatment also involves chemotherapy or radiotherapy, resurgence of cancer cells remains possible. We have thus designed a new kind of heterostructured nanobiomaterial, composed of SiO2-CaO bioactive glass as the shell and superparamagnetic γ-Fe2O3 iron oxide as the core in order to combine the benefits of bone repair thanks to the glass bioactivity and cancer cell destruction through magnetic hyperthermia. These multifunctional core-shell nanoparticles (NPs) have been obtained using a two-stage procedure, involving the coprecipitation of 11 nm sized iron oxide NPs followed by their encapsulation inside a bioactive glass shell by sol-gel chemistry. The as-produced spherical multicore-shell NPs show a narrow size distribution of 73 ± 7 nm. Magnetothermal loss measurements by calorimetry under an alternating magnetic field and in vitro bioactivity assessment performed in simulated body fluid showed that these heterostructures exhibit a good heating capacity and a fast mineralization process (hydroxyapatite forming ability). In addition, their in vitro cytocompatibility, evaluated in the presence of human mesenchymal stem cells during 3 and 7 days, has been demonstrated. These first findings suggest that γ-Fe2O3@SiO2-CaO heterostructures are a promising biomaterial to fill bone defects resulting from bone tumor resection, as they have the ability to both repair bone tissue and act as thermoseeds for cancer therapy.

Abstract
Impact of bone diseases and injury is increasing at an enormous rate during the past decades due to increase in road traffic accidents and other injuries. Bioactive glasses have excellent biocompatibility and osteoconductivity that makes it suitable for bone regeneration. Researches and studies conducted on several bioactive glasses gives an insight on the need of multi-disciplinary approaches involving various scientific fields to attain its full potential. Of late, a next generation bioactive glass called as mesoporous bioactive glass (MBG) has been developed with higher specific surface area and control over mesoporous structure that presents a new material for bone regeneration. A brief discussion and overview on the potential use of MBG as a suitable material for bone tissue regeneration and biomolecule delivery is included. Additionally, possible control of the structural and functional property based on composition and fabrication techniques are also covered. According to recent researches, MBG-implant interaction with bone forming cells for cellular growth and differentiation as well as its effect on delivery of growth factor, both in vitro and in vivo, are optimistic; yet, the complete efficacy of this material is still to be explored. Hence, in this article we will review the current development and its applications for bone tissue engineering (TE).

Abstract
Calcium magnesium silicate glasses could be suggested for the synthesis of scaffolds for hard tissue regeneration, as they present a high residual glassy phase, high hardness values and hydroxyapatite-forming ability. The use of trace elements in the human body, such as Cu, could improve the biological performance of such glasses, as Cu is known to play a significant role in angiogenesis. Nano-bioceramics are preferable compared to their micro-scale counterparts, because of their increased surface area, which improves both mechanical properties and apatite-forming ability due to the increased nucleation sites provided, their high diffusion rates, reduced sintering time or temperature, and high mechanical properties. The aim of the present work was the evaluation of the effect of different ratios of Ethanol/TEOS and total amount of the inserted ammonia to the particle size, morphology and bioactive, hemolytic and antibacterial behavior of nanoparticles in the quaternary system SiO2-CaO-MgO-CuO. Different ratios of Ethanol/TEOS and ammonia amount affected the size and morphology of bioactive nanopowders. The optimum materials were synthesized with the highest ethanol/TEOS ratio and ammonia amount as verified by the enhanced apatite-forming ability and antibacterial and non-hemolytic properties.

Abstract
Chitosan, a natural biopolymer with osteoconductive properties is widely investigated to generate scaffolds for bone tissue engineering applications. However, chitosan based scaffolds lacks in mechanical strength and structural stability in hydrated condition and thereby limits its application for bone tissue regeneration. Thus in the present study, to overcome the limitations associated with chitosan based scaffolds, we fabricated polyelectrolyte complexation mediated composite scaffold of chitosan and chondroitin sulfate incorporated with nano-sized bioglass. Developed scaffolds were successfully characterized for various morphological, physico-chemical, mechanical and apatite forming properties using XRD, FT-IR, FE-SEM and TEM. It was observed that polyelectrolyte complexation followed by incorporation of bioglass significantly enhances mechanical strength, reduces excessive swelling behavior and enhances structural stability of the scaffold in hydrated condition. Also, in-vitro cell adhesion, spreading, viability and cytotoxity were investigated to evaluate the cell supportive properties of the developed scaffolds. Furthermore, alkaline phosphatase activity, biomineralization and collagen type I expression were observed to be significantly higher over the composite scaffold indicating its superior osteogenic potential. More importantly, in-vivo iliac crest bone defect study revealed that implanted composite scaffold facilitate tissue regeneration and integration with native bone tissue. Thus, developed composite scaffold might be a suitable biomaterial for bone tissue engineering applications.

Abstract
Native tissues possess unparalleled physiochemical and biological functions, which can be attributed to their hybrid polymer composition and intrinsic bioactivity. However, there are also various concerns or limitations over the use of natural materials derived from animals or cadavers, including the potential immunogenicity, pathogen transmission, batch to batch consistence and mismatch in properties for various applications. Therefore, there is an increasing interest in developing degradable hybrid polymer biomaterials with controlled properties for highly efficient biomedical applications. There have been efforts to mimic the extracellular protein structure such as nanofibrous and composite scaffolds, to functionalize scaffold surface for improved cellular interaction, to incorporate controlled biomolecule release capacity to impart biological signaling, and to vary physical properties of scaffolds to regulate cellular behavior. In this review, we highlight the design and synthesis of degradable hybrid polymer biomaterials and focus on recent developments in osteoconductive, elastomeric, photoluminescent and electroactive hybrid polymers. The review further exemplifies their applications for bone tissue regeneration.

Abstract
The aim of this study was to investigate the effect of three synthesis parameters on the morphology and composition of nanosized binary bioactive glass particles (nBGPs) obtained through a modified Stöber process. Syntheses were conducted by varying only one parameter at a time while keeping the other parameters constant. As already mentioned in the literature, the ammonium hydroxide volume conditioned the size of the nanoparticles. Nonagglomerated monodispersed spherical particles with a diameter between 70 and 452 nm were produced. The quantity of calcium nitrate and the moment it was introduced in the sol had a tremendous impact on the quantity of calcium inserted and on the particle morphology and aggregation state. High Ca-content particles were obtained when the calcium precursor addition time was 1 h or less after the beginning of the sol-gel reaction but at the cost of a strong aggregation. A better control on the morphology, polydispersity and dispersibility of the nBGPs was achieved when the Ca(NO3)2 addition time was increased up to 6 h. However, a significant decrease of the quantity of Ca2+ inserted was also noticed. Using an intermediate (3 h) addition time, the quantity of calcium nitrate has been optimized to maximize the insertion of Ca2+ ions inside the silica particles. Finally, an optimum initial Ca/Si atomic ratio of 2, maximizing Ca insertion while limiting the salt quantity used, was found. It led to the synthesis of particles with a molar composition of 0.9SiO2-0.1CaO without any side effect on the particle stability and morphological characteristics.

Abstract
In this study, the SiO2-CaO-P2O5 ternary component of bioactive glass particles were successfully synthesized by sol-gel method, then the bioactive glass particles were pressed into tablets with dry pressing molding technology. The physicochemical structure, in-vitro bioactivity and biocompatibility of BG tablets were characterized by various methods, such as XRD、SEM、FTIR, etc. The results showed that the sol-gel bioactive glass particle was distinguished with its amorphous structure and micron-size. After being soaked in Tris-Hcl solution for 15 d, the bioactive glass tablets didn't collapse. Also, the mineralization assay in vitro showed that the bioactive glass tablets had good capability of inducing the formation of hydroxycarbonate apatite (HCA) after being immersed in simulated body fluid (SBF). In addition, the cytotoxicity assay indicated that the osteoblast (MC3T3) grew well on the surface of bioactive glass tablets. According to the above results, the bioactive glass tablets presented good mechanical strength, excellent apatite-forming activity and high biocompatibility, which demonstrated their potential applications in the field of bone defect repairing.

Abstract
Hydroxyapatite (HA) is well-known as one of the excellent bone repair biomaterials because of its chemical similarity with biological apatite. However, weak bioactivity obstructs its application. Although the bioactivity of HA bioceramic could be enhanced by the incorporation of bioactive glass (BG), the dramatic decrease of its mechanical property is consistently a disturbance to the reliable efficacy of traditional modified HA bioceramic. In this study, HA bioceramic was modified by infiltration of BG sol and formation of silicate-containing grain boundary phases during subsequent sintering. The phase compositions, microstructure, mechanical performance, in vitro degradation behaviors, and osteogenesis of the bioceramic were investigated. The modified HA bioceramic exhibited an interesting phenomenon in which the HA grains were uniformly enveloped by the small silicate-containing grains in the boundaries of HA grains. The microporosity of modified HA bioceramics was up to 25.27% ± 0.01%, much higher than that of unmodified HA bioceramic (1.74% ± 0.27%). The compressive strength of the modified HA bioceramic via BG sol infiltration was much higher than that of the HA bioceramic modified by BG via mechanical blending method, though slightly lower than that of the blank. Moreover, mouse bone mesenchymal stem cells (mBMSCs) cultured on modified bioceramic displayed better adhesion morphology and proliferation, and had an enhanced expression of osteogenesis-related genes. This study offers a new strategy to improve the bioactivity of HA bioceramic without obvious deterioration in mechanical strength.

Abstract
Silicate-based bioactive glass nanoparticles (BGN) are gaining increasing attention in various biomedical applications due to their unique properties. Controlled synthesis of BGN is critical to their effective use in biomedical applications since BGN characteristics, such as morphology and composition, determining the properties of BGN, are highly related to the synthesis process. In the last decade, numerous investigations focusing on BGN synthesis have been reported. BGN can mainly be produced through the conventional melt-quench approach or by sol-gel methods. The latter approaches are drawing widespread attention, considering the convenience and versatility they offer to tune the properties of BGN. In this paper, we review the strategies of sol-gel processing of BGN, including those adopting different catalysts for initiating the hydrolysis and condensation of silicate precursors as well as those combining sol-gel chemistry with other techniques. The processes and mechanism of different synthesis approaches are introduced and discussed in detail. Considering the importance of the BGN morphology and composition to their biomedical applications, strategies put forward to control the size, shape, pore structure and composition of BGN are discussed. BGN are particularly interesting biomaterials for bone-related applications, however, they also have potential for other biomedical applications, e.g. in soft tissue regeneration/repair. Therefore, in the last part of this review, recently reported applications of BGN in soft tissue repair and wound healing are presented.

Abstract
Dental pulp vitality is extremely important for the tooth viability, since it provides nutrition and forms the dentin. Bioactive glasses (BGs) may be promising materials for pulp repair due to their excellent abilities of rapidly bonding to bone and stimulating new bone growth. However, the unsatisfied handling property, low plasticity, and poor rapid-setting property of traditional BGs limit its application in vital pulp therapy. Spherical bioactive glasses (SBGs) exhibited higher osteogenesis and odontogenic differentiation than irregular BGs. This study focuses on the application of SBGs with rapid setting property for dental pulp repair. Here, SBGs with various compositions were successfully synthesized by a sol-gel process using dodecylamine (DDA) served as both a catalyst and a template. The maximum content of CaO in SBGs was about 15%. The non-bridge oxygen amounts of the SiO network and the apatite-forming ability increased with the content proportion of CaO and P2O5. Bioactive glass pulp capping materials (BGPCMs) were prepared by mixing the SBGs powders and the phosphate buffer solution (PBS). The K3CaH(PO4)2 and hydroxyapatite (HA) formed between SBGs particles as soon as they were mixed with PBS solution. The compressive strengths of fully set BCPCM-2 molded were measured to be 31.76±1.9577MPa after setting for 24h. The K3CaH(PO4)2 and the low crystallinity HA phases at the initial stage of solidification transformed to crystalline HA for 3days, and the compressive strength was still higher than 10MPa. Additionally, SBG-2 with a designed molar composition of 35% SiO2, 55% CaO and 10% P2O5 more promoted dental pulp cell proliferation, and could be potential pulp capping applications.

Abstract
The lack of safe and efficient drug and gene delivery vectors has become a major obstacle for the clinical applications of drug and nonviral gene therapy. To date, for nonviral gene vectors, most studies are focused on cationic polymers, liposomes, and modified inorganic nanoparticles which have shown high cellular toxicity, low transfection efficiency, or nondegradation. Additionally, few biodegradable biomaterials demonstrate intrinsic high binding abilities to both drug and gene. Bioactive glasses (BGs) have achieved successful applications in bone regeneration due to their high biocompatibility and biodegradation. Here, for the first time, we demonstrate the intrinsic ultrahigh drug and miRNA binding ability of bioactive glass nanoparticles (BGNs) without any cationic polymer modification. BGNs demonstrate an over 45-fold improvement in hydrophilic drug loading (diclofenac sodium) and 7-fold enhancement in miRNA binding over their corresponding silica nanoparticles. The hydrophilic drug loading ability of BGNs (>45 wt % loading) is also higher than that of most other reported inorganic nanoparticles, including mesoporous silica nanoparticles. BGNs show significantly lower cytotoxicity and higher cellular uptake and miRNA transfection efficiency compared to those of commercial transfection reagents polyethylenimine and lipofectamine 3000. Our results demonstrate that BGNs may become a new competitive vehicle for drug and gene delivery applications. This study may also provide a new strategy to develop novel biomaterials with intrinsic drug and gene binding ability for disease therapy.

Abstract
BACKGROUND There is limited knowledge regarding differentiation of osteoclasts in the presence of nanoscale bioactive glass (nBG). This investigation examined increasing concentrations of 45S5 nBG and their influence on osteoclast differentiation. MATERIALS & METHODS Different concentrations of 45S5 nBG were cultured up to 14 days with the murine RAW264.7 cell line and human primary monocytes cultured with M-CSF and RANKL. RESULTS Culturing cells for 14 days with 500 μg/ml nBG showed a viability of 100%; however DNA synthesis was reduced, supporting differentiation into osteoclast-like cells. Using RAW cells, activation of nine genes, including cell fusion genes, occurred in an nBG concentration dependent manner. Low concentrations of nBG increased expression of genes involved in commitment to cell fusion, whereas high concentrations increased gene expression supporting osteoclast-like differentiation. CONCLUSION nBG enhances both RAW264.7 and human osteoclast differentiation. nBG controlled gene expression in a concentration dependent manner could reflect normal regulation during bone growth.

Abstract
Biodegradable elastomeric biomaterials have attracted much attention in tissue engineering due to their biomimetic viscoelastic behavior and biocompatibility. However, the low mechanical stability at hydrated state, fast biodegradation in vivo, and poor osteogenic activity greatly limited bioelastomers applications in bone tissue regeneration. Herein, we develop a series of poly(octanediol citrate)-polyhedral oligomeric silsesquioxanes (POC-POSS) hybrids with highly tunable elastomeric behavior (hydrated state) and biodegradation and osteoblasts biocompatibility through a facile one-pot thermal polymerization strategy. POC-POSS hybrids show significantly improved stiffness and ductility in either dry or hydrated conditions, as well as good antibiodegradation ability (20-50% weight loss in 3 months). POC-POSS hybrids exhibit significantly enhanced osteogenic differentiation through upregulating alkaline phosphatase (ALP) activity, calcium deposition, and expression of osteogenic markers (ALPL, BGLAP, and Runx2). The high mechanical stability at hydrated state and enhanced osteogenic activity make POC-POSS hybrid elastomers promising as scaffolds and nanoscale vehicles for bone tissue regeneration and drug delivery. This study may also provide a new strategy (controlling the stiffness under hydrated condition) to design advanced hybrid biomaterials with high mechanical properties under physiological condition for tissue regeneration applications.

Bio-templated bioactive glass particles with hierarchical macro-nano porous structure and drug delivery capability. Colloids Surf B Biointerfaces 2015; 135:825-832. [PMID: 25858191 DOI: 10.1016/j.colsurfb.2015.03.038] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2014] [Revised: 02/22/2015] [Accepted: 03/16/2015] [Indexed: 01/02/2023]
Abstract
Hierarchically porous bioactive glass particles (BGPs) were synthesized by a facile sol-gel process using pollen grains as the templates. The synthesized pollen-templated bioactive glass particles (PBGPs) exhibited dual macro-nano porous structure. The macro pores (∼ 1 μm) were inherited from the template of pollen grains while the nano pores (∼ 9.5 nm) were induced by the intrinsic mechanism of the sol-gel process. PBGPs possessed a high specific surface area (111.4m(2)/g) and pore volume (0.35 cm(3)/g). Hydroxyapatite (HA) formation on PBGPs was detected within 3 days after immersion in simulated body fluid (SBF). Due to their larger specific surface area and pore volume, PBGPs could be loaded with more tetracycline hydrochloride (TCH) than non-templated BGPs and conventional melt-derived 45S5 BGPs. In addition, PBGPs exhibited a low initial burst release (within 10% of the loaded amount) within 18 h and a sustained release with a two-stage release pattern for up to 6 days in phosphate buffered saline (PBS). The antibacterial assay confirmed that the TCH-loaded PBGPs could release TCH within 5 days, and the released TCH could reach the minimum inhibitory concentration (MIC) against Escherichia coli. MTT assay indicated that PBGPs showed non-cytotoxic effects toward human hepatocellular carcinoma (Hep G2) cells after co-culture for up to 72 h in vitro. These results showed that the biocompatible hierarchically macro-nano porous PBGPs are potential for bone regeneration and local drug delivery applications.

Abstract
To improve treatments of bone or dental trauma and diseases such as osteoporosis, cancer, and infections, scientists who perform basic research are collaborating with clinicians to design and test new biomaterials for the regeneration of lost or injured tissue. Developed some 40 years ago, bioactive glass (BG) has recently become one of the most promising biomaterials, a consequence of discoveries that its unusual properties elicit specific biological responses inside the body. Among these important properties are the capability of BG to form strong interfaces with both hard and soft tissues, and its release of ions upon dissolution. Recent developments in nanotechnology have introduced opportunities for materials sciences to advance dental and bone therapies. For example, the applications for BG expand as it becomes possible to finely control structures and physicochemical properties of materials at the molecular level. Here, we review how the properties of these materials have been enhanced by the advent of nanotechnology, and how these developments are producing promising results in hard-tissue regeneration and development of innovative BG-based drug delivery systems.
