Opis

Fluorescence is the most popular technique in chemical and biological sensing and this book provides systematic knowledge of basic principles in the design of fluorescence sensing and imaging techniques together with critical analysis of recent developments. Its ultimate sensitivity, high temporal and spatial resolution and versatility enables high resolution imaging within living cells. It develops rapidly in the directions of constructing new molecular recognition units, new fluorescence reporters and in improving sensitivity of response, up to the detection of single molecules. Its application areas range from the control of industrial processes to environmental monitoring and clinical diagnostics. Being a guide for students and young researchers, it also addresses professionals involved in basic and applied research. Making a strong link between education, research and product development, this book discusses prospects for future progress.
