The Novartis Foundation Series is a popular collection of the proceedings from Novartis Foundation Symposia, in which groups of leading scientists from a range of topics across biology, chemistry and medicine assembled to present papers and discuss results. The Novartis Foundation, originally known as the Ciba Foundation, is well known to scientists and clinicians around the world.

In many ways silicon was considered a typical opposite of carbon, although the two elements are closely related as to their electronic structure, both having four valence electrons. The properties of their compounds are, however, extreme ly different. Both form extended structures, but in different ways - carbon by covalent carbon-carbon bonds; silicon by polar silicon- -oxygen-silicon bonds. The complex carbon compounds are integral parts of all living matter, plants and animals. The corresponding silicon compounds build up a major part of dead matter, soils and minerals. As recently as twenty years ago the title of this Symposium, "BiOChemistry of Silicon", would have been considered as contradictio in adjecto. However, the development in the field has, during the past fifteen years, been overwhelming and has convinced us that silicon is a necessary element in the life processes, for animals as well as for plants. Interesting therapeutical uses have been suggested, but we have also become increasingly aware of serious occupational diseases - asbestosis and silicosis - and of possible cancerogenic effects. It is our hope that this volume will give some idea about various aspects of silicon compounds which were discussed during the Symposium.

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.

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.
