Preface

Chromogenic assays (color detection) result in colored reaction products. By detecting the color change before and after the reaction, substance concentration can be determined by the naked eye, light microscopes, or spectrophotometers. Because of their rapid, direct, specific, convenient, and sensitive features, color detection exhibits great potential in the field of quality monitoring, chemical technology, nanophysics, and clinical medicine. The intention of this book is to provide readers with a comprehensive overview of the principles, features, and

In the introduction chapter, Cao and Zeng briefly introduce the application of color detection in food analysis and biochemical detections, including protein, reducing

Mikhail Dolomatov provides new data on the color phenomenon for complex and simple substances in recent years, and introduces the effects of the relationship of physical and chemical properties and color characteristics (in color systems RGB or

Natalia Grigoryeva and Ludmila Chistyakova present several experimental approaches to study the metabolic mechanisms in single photosynthetic cells in vivo. They are accompanied by several examples of in vivo investigations. Three main CLSM tools will be discussed in detail: spectral imaging, fluorescent

Volkan Kılıç, Nesrin Horzum, and Mehmet Ertugrul Solmaz present a review of smartphone-based colorimetric determination of chromogenic assays that has been provided on color spaces, existing color matching and detection techniques, hardware and software designs, and performance metrics that have been developed

Amanda Pereira Franco dos Santos, Kissya Kropf da Silva, Gisele Alves Borges, and Luiz Antonio d'Avila review the colorimetric techniques designed for quality monitoring and the detection of adulteration in fuels, especially simple, quick,
