Carbon dots are a new class of water dispersible multicolor emissive carbon nanostructure materials with outstanding applications in multidisciplinary research area. Analytical applications of carbon dots have rapidly expanded into various disciplines including environmental, pharmaceutical, forensic, food, and biomedical sciences in the last few years. This is a very timely book that will prove to be a valuable one both for those working in materials chemistry and analytical chemistry and for those entering in this field. The organizational approach we take in this book builds from the synthetic approaches, properties, characterization, and analytical applications of carbon dots. Our challenge has been to provide a comprehensive description on synthetic routes (top-down and bottom-up) and analytical tools for the characterization of carbon dots, and their integration with a wide variety of analytical techniques for the development of green analytical strategies for sensing of trace level chemical species and imaging of cells. The main object of this book is to report on new studies of carbon dots in analytical technologies for molecular sensing and cell imaging. Further, to address the increasing emphasis in nanoanalytical sciences to integrating carbon dots with various analytical techniques, and creation of awareness on analytical chemistry of carbon dots, we organized the book into 26 chapters that provide a comprehensive description on four aspects of carbon dots including different synthetic approaches for the preparation of carbon dots, properties of carbon dots, analytical techniques for the characterization of carbon dots, and their integration with different analytical techniques for sensing trace level analytes (inorganic, organic, biomolecules, and explosives) and imaging of cells. The text begins with core concepts on the topdown (arc discharge, laser ablation, electrochemical etching, chemical oxidation and ball milling methods) and bottom-up (hydrothermal, solvothermal, pyrolysis, carbonization, and microwave) routes for preparation of carbon dots with specific optical properties and surface chemistry, which is fundamental concept in the development of carbon dots-based analytical strategies. In the chapters dealing with properties and characterization of carbon dots, optical properties (absorption, phosphorescence, photoluminescence, chemi- and electrochemical-luminescence, and upconversion luminescence) and physicochemical (quantum yield, crystallinity, photostability, cytotoxicity, and catalytic) properties are well described. Potential applications of carbon dots in sample preparations (solid-phase extraction, dispersive solid-phase extraction, magnetic solid-phase microextraction) and separation science are well discussed. Analytical applications of carbon dots are introduced in a series of 20 chapters with an emphasis on the integration of carbon dots with various analytical techniques for molecule sensing and cell imaging studies. These chapters provide recent advances of carbon dots-based electroanalytical tools for the detection of various target molecules. Contributors have made significant contribution in discussing the carbon dots in spectroscopic (UV_visible, fluorescence, and MALDI-MS) techniques for recognition of trace level analytes and fluorescence microscopic techniques for imaging of various cells. The subsequent chapters also describe the applications of carbon dots in forensic science, food quality, agriculture science, wastewater treatment and catalysis. Throughout the book we have illustrated the fundamental concepts and mechanistic approaches of carbon dots in analytical chemistry referring to the problems in sample preparation, separation science, environmental, forensic, agriculture, and biomedical sciences. The contributors have considerable experience in carbon dots applications in analytical chemistry and have pioneered the study of carbon dots-based analytical approaches for recognition of various molecules and imaging of cells.
