1.INTRODUCTION
Development of metal, ceramic, polymer or materials of biological origin for use in medicine is a very important research area of the last decades. Scientists made great innovations in the production of artificial organs and tissues such as dental and orthopedic prostheses, artificial veins and heart valves, contact lenses, tissue engineering scaffolds, diagnostic systems, etc. As the knowledge on materials and biological systems improved,new areas such as interaction between the material and cells, effect of therapeutic agents at molecular level, the relation between the molecular structure and macroscopic properties became important research lines. Scientists are increasingly interested in mimicking the biological systems, under- standing cell-cell communications and modeling the structures that already exist in nature. This curiosity makes them search individual molecules, study interac- tions between the functional groups, signaling between the cells at micro and nano levels to be able to
control the properties of the artificial and biological systems. Technologies based on micro and nano levels involve synthesis and utilization of materials, devices and systems in which at least one dimension is less than 1 mm or in the submicron range, respectively.
