Preface

With the advent of new surface and thin layer technologies, including different coating methods, it is now possible to make new materials with extreme physicochemical properties.

The new materials (films, mono- and multi-layers, nanostructures, composites etc) produced using the new methods have been used in many places in various fields of engineering technology and life science.

In this book, studies written by renowned researchers draw the reader's attention to different technologies of film fabrication eg, deposition, from liquid and solid phases, sputtering, and nanoscale layer fabrications. Some measuring methods by which the extreme material and life science parameters of the layers produced can be determined are also presented.

The reader will find many examples of medical–biological applications, highlighting the compatibility problems of tissues with the materials deposited (coating behavior in living environments).

We hope that the book will serve as an interesting scientific and practical base for people interested in applications of coatings for medical–biological use.
