Abstract
The fluorescence fingerprint, also known as the excitation-emission matrix （EEM）, is a set of fluorescence spectra acquired at consecutive excitation wavelengths to create a three-dimensional diagram. The pattern of this diagram, rather like the actual fingerprint, is unique for each measured sample, containing abundant information about the constituents making up the sample. Therefore, fine distinctions can be made between samples, which would otherwise be indistinguishable. Detection of mycotoxins in wheat and nutmeg using this technology are introduced in this paper.
