Preface

in industrial production.

Electrophoresis is a widely used method in the field of life sciences, having multiple practi‐ cal applications both in physical, chemical, biochemical, and molecular biology research and

Electrophoresis is defined as a physicochemical technique by which charged particles migrate and separate on a certain physical support under the influence of an electric field. An electro‐ phoresis system is composed of two electrodes with the opposite chargecathode and anode connected through a medium called electrolyte. The mobility of an ionic particle is deter‐ mined by its shape, size, electrical charge, and chemical-physical factors of electrophoresis temperature, electrical parameters, pH, viscosity, or pore size of the electrophoretic support. Although the electrokinetic phenomenon was observed for the first time in the early 1800s, the method was developed in the 1930s, and since then, separation processes and chemical analy‐ sis techniques based on electrophoresis have continued to be developed, providing relevant data in the process of discovery of new non-bio-materials and research of biomolecules and their involvement in various biochemical processes that are studied, as well as to the clinical

constant parameters already chosen as indicators of the health state of an organism.

This book contains 8 chapters describing various applications of this technique in biochemis‐ try, molecular biology, and physical chemistry. The chapters describe the link between the exposed method and its applications in a very explicit manner and offer a wide range of practical examples. At the same time, the book aims to provide a vision of how future meth‐ ods will evolve and their further development and the improvements that are needed to be made to the exposed techniques; therefore, a particular attention has been given to the de‐ scribed techniques as true guidelines in the fields where electrophoresis is recommended to be used, making it useful for not only the researchers but also the laboratory technicians.
