Available in PDF, EPUB and Kindle. Book excerpt: Inorganic glasses are successfully used in the biomedical field, in particular degradable glasses have found applications in tissue engineering, bone regeneration and tooth remineralisation. Silicate glasses are the most commonly used ones but phosphate and borate glasses are attracting more and more interest owing to their special properties, differing from those of silicate bio-glasses. Phosphate and borate glasses thus open up potential routes for new therapeutic applications. This book focuses on these emerging materials. Bridging the phosphate and borate glasses communities, this book provides a fundamental treatment of atomic structure and physicochemical properties before highlighting their current and potential future applications. Phosphate and borate glasses not only feature a broader range of glass formation than silicate glasses. Their ability to completely dissolve in water with the solubility varying over orders of magnitude with compositional changes, makes them exciting materials for delivering therapeutic agents into the human body. Biomaterials scientists working in glasses, hard tissue engineering and regenerative medicine will find this a must-have book to own, alongside their more traditional silicate glass tomes.
Book Synopsis Dissolution of Borate Glasses and Precipitation of Phosphate Compounds by : Jaime Lynn George
Download or read book Dissolution of Borate Glasses and Precipitation of Phosphate Compounds written by Jaime Lynn George and published by . This book was released on 2015 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Borate glasses have been developed for biomedical applications such as scaffolds for soft tissue and bone repair. The dissolution processes of borate glasses in phosphate-containing aqueous solutions were studied by [mu]-Raman spectroscopy which provided information about the types and concentrations of borate species released into the solution as a function of time and characterized the formation of calcium phosphate reaction products on the glass surface. Boric acid molecules (H3BO3) and borate anions (B(OH)4−) can be detected in solution and their relative concentrations depend on the solution pH. Static and dynamic single-pass flow-through experiments were employed to study the dissolution kinetics of a borate bioactive glass 13-93B3 in water, simulated body fluid (SBF), and other solutions. As the glasses react, B-, Ca-, Na-, K-, Mg-, and P-species were released from the glass and a magnesium-containing amorphous calcium phosphate (ACP) or hydroxyapatite (HAP) layer formed on the surface of the glass. The formation of crystalline hydroxyapatite was favored with faster flow rates, longer reaction times, and increased phosphate concentration in solution. Under static conditions, the dissolution rates are initially described by a reaction-controlled model (linear kinetics), but after the glass is ~25-30% reacted, a diffusion-controlled model (parabolic kinetics) better describes the dissolution rates. The change in reaction mechanism is attributed to the diffusion of species from the glass through the ACP layer. The activation energy for the reaction-controlled process is 41.1±0.6 kJ/mol, whereas the activation energy for the diffusion process is 32.3±0.1 kJ/mol. For the SPFT experiments, glasses dissolved faster under faster flow rates and smaller glass volumes. The ion release rate was calculated and found to range from 1.7x10−5 g/m2/s for slow flow rates to 1.1x10−3 g/m2/s for lower glass volumes."--Abstract, page iv.

Book excerpt: "For the past 30 years, the bioactive characteristics of special glass compositions have been demonstrated. Until now, phosphate containing soda-lime-silicate glasses such a 45S5 Bioglass®, were used to stimulate bone repair. Through the formation of an osteoconductive layer of hydroxyapatite (the main inorganic compound of bone) on the glass surface, direct bonding with bone will then occur. The rate of formation of hydroxyapatite was studied for the first silica-free borate glass of composition analogue to 45S5 and for a partially crystallized 45S5 glass. An cell-free process has been modeled to assess the formation of hydroxyapatite on the glass. The process involves the reaction of borate glass particles in phosphate solution of various molarity and starting pH. The formation of hydroxyapatite was observed best in a 0.1 Molar phosphate solution for both glasses. The reaction products have been investigated using X-ray diffraction (XRD), Infrared (IR) spectroscopy, Scanning Electron Microscopy (SEM) and Energy Dispersive Spectroscopy (EDS) and Inductively Coupled Plasma - Atomic Emission Spectrometer (ICP). The positive outcome of the model lead to further investigation of the borate glass. In vitro experiments were performed using MC3T3-E1 bone cells. The borate glass provided a marginally suitable environment for the growth of cells due to the release of boron. Successful in vivo experiments demonstrated bone growth around the borate glass particles very similar to that for the commercially used 45S5 glass. The successful bioactive response obtained with the first silica-free glass composition opens the way to the development of other compositions for bioactive use. Based on our study, future medical applications of a bioactive borate glass may dramatically reduce the rehabilitation time for patients"--Abstract, leaf iv.

Book Synopsis The Effect of Sulfur on Structure and Conversion of Bioactive Borate Glasses by : Ali Mohammadkhah
Download or read book The Effect of Sulfur on Structure and Conversion of Bioactive Borate Glasses written by Ali Mohammadkhah and published by . This book was released on 2012 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The effect of sulfur on glass structure and the conversion process of bioactive CaO-LI2O-B2O3 glasses were studied. One glass without and two glasses with different amounts of sulfur were made using conventional melting and dry quenching techniques. These glasses reacted with a phosphate solution and converted to hydroxyapatite. Particles (150-355[mu]m) were reacted in 0.25 and 0.5 molar K2HPO4 solutions at 37°C for 2 to 96 hours. The weight loss of the particles and the final pH of the solution were measured. The weight loss measurements indicated that the reaction rate increases with increasing the sulfur content. Sulfur was released from the glass, causing the pH of the solution to decrease, but was absent in the reacted layer. In the in-vivo studies, the effect of sulfur and phosphorus on the conversion of two different bioactive borate glasses was studied, in-vivo. Discs made from two sulfur-free glasses (CaLB-0 and 93B3-0) and two sulfur-containing glasses (CaLB-12 and 93B3-6) were implanted in a subcutaneous site in rats for 2, 4, and 12 weeks. Each rat remained healthy during the experiment and there were no sign of infection or necrosis at the implantation site. The CaLB glass discs reacted with the body fluids and formed a thin calcium phosphate reacted layer on their surface, but the 93B3 glass discs reacted to form a thicker calcium phosphate reacted layer with an onion-skin structure. Compared the phosphorus-free CaLB implants to phosphorus-containing 93B3 implants the CaLB implants absorbed 2 times more phosphorus from the body fluids to form the calcium phosphate reacted layer. Compared to the CaLB implants, the connective tissue attached to the 93B3 implants was ~3 times thicker, and contained more blood vessels and collagen. For all of the sulfur-containing implants sulfur released to the body fluids and was not presented in the reacted materials"--Abstract, leaf iv.

Book Synopsis Inorganic Biomaterials by : Xiang C Zhang
Download or read book Inorganic Biomaterials written by Xiang C Zhang and published by Smithers Rapra. This book was released on 2014-06-26 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a practical guide to the use and applications of inorganic biomaterials. It begins by introducing the concept of inorganic biomaterials, which includes bioceramics and bioglass. This concept is further extended to hybrid biomaterials consisting of inorganic and organic materials to mimic natural biomaterials. The book goes on to provide the reader with information on biocompatibility, bioactivity and bioresorbability. The concept of the latter is important because of the increasing role resorbable biomaterials are playing in implant applications. The book also introduces a new concept on mechanical compatibility - 'mechacompatibility'. Almost all implant biomaterials employed to date, such as metal and ceramic implants, do not meet this biological requirement as they have far higher modulus than any biomaterials in the body. The practical techniques that are used in the characterization of biomaterials, including chemical, physical, biological, microscopy and mechanical characterization are described. Some specialised techniques are also introduced such as Synchrotron Micro-Computed Tomography (u-CT) and Magnetic Resonance Imaging (MRI). The reader is given important information on new biomaterials development for orthopaedic and other areas, including controlled release technology, hydroxyapatite and hybrid bioresorbable materials. Finally the book provides a guide to regulatory considerations, an area which is often overlooked, but is an important part of R&D and manufacturing of medical materials and devices.
