Preface

Dyes and pigments play an important role in our everyday lives. Synthetic dyes and pigments are found in numerous objects we utilize every day, from dyes coloring our clothes and pigments in our paintings to advanced dyes used in recordable DVDs and innovative fluorescent dyes employed in live-cell imaging. The versatility of the known dyes and pigments is enormous and their uses and applications are countless. The global demand for new dyes and pigments with novel properties and applications is constantly growing, and thus research attempts to develop these new dyes and pigments are currently intensifying. Of course, a great deal of the currently conducted research aims at a better understanding of the properties and application scope of existing dyes and pigments. However, bulk volumes of dyes and pigments and related byproducts associated with their production and end uses

are contaminating the environment and polluting valuable water resources.

Acknowledging these facts, this book covers two main areas of research, and the book is organized into three sections. The first section is the Introduction. In the second section, the book explores new trends in the research of dyes and pigments, focusing on smart and functional dyes and pigments and their uses in textile dying, analytical chemistry, bioimaging and biosensing, and novel chromic and energy-related applications.

The third section examines new trends in the treatment of dye and pigment waste. Techniques employing newly developed materials or modified clays as well as

As academic editor of this book, I am grateful to all authors who have contributed chapters covering all pertinent research areas that address important scientific, industrial, and technological problems. It has been my pleasure and privilege to read, interact with, and learn from the work of all the authors. A big thanks goes to

I am grateful to my old friend and colleague Dr. Dimitris Matiadis (researcher at NCSR Demokritos, Athens, Greece) for the stimulating discussions related to novel synthetic dyes (especially fluorescent ones) and my lovely wife (Dr. Kalliopi Tzavlaki) who always makes sure to keep me updated regarding new trends in

Last (but not least), I would like to acknowledge TdB Labs, the company I am happy to have worked at as a Senior Research Scientist since 2019, for providing me with space, time, and motivation to learn more about the intriguing and wide research
