System and method for the identification and quantification of a biological sample suspended in a liquid

摘要

A system for the identification and quantification of a biological sample suspended in a liquid includes a fluorescence excitation module with at least one excitation light source; a sample interface module optically coupled to the fluorescence excitation module for positioning a biological sample to receive excitation light from the at least one excitation light source; a fluorescence emission module optically coupled to the sample interface module and comprising at least one detection device for detecting fluorescence excitation-emission matrices of the biological sample; and a computer module operatively coupled to the fluorescence emission module. The computer module performs multivariate analysis on the fluorescence excitation-emission matrices of the biological sample to identify and quantify the biological sample. The multivariate analysis may comprise extended partial least squared analysis for identification and quantification of the biological sample. A method for the identification and quantification of a biological sample suspended in a liquid is also provided.
