Book Description
The liberation of poly(dimethylsiloxane) fluid, from the inside of silicone breast implants by diffusion and/or implant rupture, has been associated with a variety of rheumatologic disorders in patients who have received them. Continued use of these materials necessitates a better understanding of how they are created and/or utilized by biological systems. In order to determine if a fibrinogen-dependent process could play a role in the dissemination of PDMS fluid in vivo, I used histological methods in conjunction with ICP-AES to assess the dissemination of silicone droplets in normal mice and in mice lacking fibrinogen. I found that mice lacking fibrinogen had no evidence of dissemination after an administration of emulsified PDMS. In contrast, mice with normal amounts of fibrinogen showed significant evidence of dissemination, suggesting that fibrinogen has a mechanistic role on the dissemination of PDMS in vivo. I also investigated a model biological system capable of processing silicon in nature. Marine diatoms use short cationic peptides to synthesize silica. I hypothesized that if the human body was capable of silicone degradation, such peptide sequences or the key residues therein might be involved. Therefore, I characterized the reaction kinetics and resulting product morphology attributed to several silica-precipitating peptide sequences derived from the diatom Cylindrotheca fusiformis in order to better understand how biologic systems process silicon. During the course of my investigations, I used the model system to produce novel silica nano-structures and incorporate them into polymeric matrices for device application. Herein I present my research on silicon-based materials and its relevance to bioengineering. The topics covered by my research include: (1) the role of fibrinogen in the dissemination of PDMS in vivo, (2) the kinetics of silica formation mediated by cationic peptides in vitro, (3) the formation of novel silica nanostructures by those same peptides and (4) the development and characterization of a silica-containing organic/inorganic hybrid material utilizing a silica-precipitating peptide.

Book Description
Silicon Carbide (SiC) is a wide-band-gap semiconductor biocompatible material that has the potential to advance advanced biomedical applications. SiC devices offer higher power densities and lower energy losses, enabling lighter, more compact and higher efficiency products for biocompatible and long-term in vivo applications ranging from heart stent coatings and bone implant scaffolds to neurological implants and sensors. The main problem facing the medical community today is the lack of biocompatible materials that are also capable of electronic operation. Such devices are currently implemented using silicon technology, which either has to be hermetically sealed so it cannot interact with the body or the material is only stable in vivo for short periods of time. For long term use (permanent implanted devices such as glucose sensors, brain-machine-interface devices, smart bone and organ implants) a more robust material that the body does not recognize and reject as a foreign (i.e., not organic) material is needed. Silicon Carbide has been proven to be just such a material and will open up a whole new host of fields by allowing the development of advanced biomedical devices never before possible for long-term use in vivo. This book not only provides the materials and biomedical engineering communities with a seminal reference book on SiC that they can use to further develop the technology, it also provides a technology resource for medical doctors and practitioners who are hungry to identify and implement advanced engineering solutions to their everyday medical problems that currently lack long term, cost effective solutions. Discusses Silicon Carbide biomedical materials and technology in terms of their properties, processing, characterization, and application, in one book, from leading professionals and scientists Critical assesses existing literature, patents and FDA approvals for clinical trials, enabling the rapid assimilation of important data from the current disparate sources and promoting the transition from technology research and development to clinical trials Explores long-term use and applications in vivo in devices and applications with advanced sensing and semiconducting properties, pointing to new product devekipment particularly within brain trauma, bone implants, sub-cutaneous sensors and advanced kidney dialysis devices

Book Description
The publication of this book was undertaken with two purposes in view: to bring together informatian on the deposition by living organ isms of unique skeletal structures composed of amorphous silica, and to review recent data on the involvement of silicon in physiological and biochemical processes. Although widely varying viewpoints are represented, all the contributors are very interested in the events in volved in the formatian of siliceaus structures and their function. Data presented deal with these questions in a variety of plant and animal systems, and at levels ranging from the evolutionary to the biochemical and ultrastructural. Innovations in electron microscopy and, indeed, the advent of electron microscopy itself, have stimulated many ultra structural studies of silica deposition, work which has deepened and widened the interest in those organisms which routinely produce "glassy skeletons. " The question of how silicon participates in biological systems in volves a spectrum of fields that indudes the chemistry of silicon per se, its biogeochemistry, biochemistry, ecology, and so forth. In this book, however, attention is focused up on the biological aspects of silicon and siliceous structures, with emphasis on the evolutian, phylogeny, morphology, and distribution of siliceaus structures, on the cellular as peets of silica deposition, and on the physiological and biochemical roles of silicon. This volume represents the first compilatian of such data. Because such a variety of subjects and fields are covered, the reader will have to glean for himself some of the comparative aspects of the data.

Book Description
During evolution silica deposition has been used in Protozoa, Metazoa and in plants as skeletal elements. It appears that the mechanisms for the formation of biogenic silica have evolved independently in these three taxa. In Protozoa and plants biosilicification appears to be primarily driven by non-enzymatic processes and procedes on organic matrices. In contrast, in sponges (phylum Porifera) this process is mediated by enzymes; the initiation of this process is likewise dependent on organic matrices. In this monograph the role of biosilica as stabilizing structures in different organisms is reviewed and their role for morphogenetic processes is outlined. It provides an up-to-date summary of the mechanisms by which polymeric biosilica is formed. The volume is intended for biologists, biochemists and molecular biologists, involved in the understanding of structure formation in living organisms and will also be very useful for scientists working in the field of applied Nanotechnology and Nanobiotechnology.
