During the last few decades, biomineralization has been intensively studied, due to its involvement in a wide range of biological events; starting with the formation of bones, teeth, cartilage, shells, coral (so-called physiological mineralization) and encompassing pathological mineralization, i.e. the formation of kidney stones, dental calculi, osteoporosis, arteriosclerosis, osteogenesis imperfecta, etc. During the same period, biomineralization has become a hot topic for world-wide research throughout the world, due to the growing expectations of a good quality and duration of life by the ever-increasing population of the aged. Young people, in particular, also make increasing demands on the quality and the appearance of the existing implants available on the market. The general goals of research and manufacture are now to create and improve implants for various applications in the human body, as well as to prevent diseases leading to the formation of minerals such as hydroxyapatite (implicated, for example, in osteogenesis, kidney stones, dental calculi, arteriosclerosis – all problems which mainly affect women).The results presented in this book will make a significant contribution to the application of the modified surfaces of widely-studied materials as a model system for hydroxyapatite-coating, to the cultivation of cells on surfaces, as well as to the growth of hydroxyapatite by applying new technologies (such as laser-liquid-solid interaction) that facilitate nucleation and growth. In this way, materials and layers having possible applications as implants, biosensors, etc. can be obtained. The in vitro system described here is universal and can be applied not only to the production of hydroxyapatite coatings for implants, but also to investigating the basic mechanisms of mineral-formation diseases and thus identify new directions for prophylaxis. This will then make a strong contribution to improving the quality and duration of life of the population. The aims of the work presented in this book are: 1. to obtain modified inorganic materials with chemically and topographically controlled surfaces, and to study the influence of: (i) the base material (metal, semiconductor, insulator), (ii) implanted inorganic ions as nucleation sites on the surface of the base material, (iii) surface-grown nanostructures, (iv) surface-grown porous silicon layers, and (v) the effect of surface-deposited organic materials on the nucleation and growth of hydroxyapatite layers using two approaches (biomimetic and laser-liquid-solid interaction). The second aim is to develop a universal in vitro system for the study, of the process of biomineralization, by mimicking in vivo situations.This book will therefore be essential reading not only for researchers and manufacturers in the field of ceramics, but also for doctors, dentists, gerontologists and cosmetologists. Pramatarova and Pecheva (both solid state physics, Bulgarian Academy of Sciences, Sofia) describe two approaches for growing hydroxyapatite layers on variously modified surfaces from super-saturated aqueous inorganic solution. Such growth can facilitate research into biomineralization as it occurs in the formation of kidney stones, atherosclerosis, and other diseases. It can also help research into designing implants such as synthetic bones and teeth.PPN: PPN: 1727621395Package identifier: Produktsigel: ZDB-1-SNTA
