Description:The validation and standardization of fluorescence methods is still in its infancy as compared to other prominent analytical and bioanalytical methods. Appropriate quality assurance standards are however a prerequisite for applications in highly regulated fields such as medical diagnostics, drug development, or food analysis.For the first time, a team of recognized international experts has documented the present status of quality assurance in fluorescence measurements, and outlines concepts for establishing standards in this field.This first of two volumes covers basic aspects and various techniques such as steady-state and time-resolved fluorometry, polarization techniques, and fluorescent chemical sensors.
