Non-Negative Matrix Factorization to unmix several fluorescence spectra and remove autofluorescence from in vivo spectrally resolved acquisitions

Not Accessible

Your library or personal account may give you access

Abstract

Plurality of specific fluorescent markers in multiplexing, and autofluorescence of biological tissues limit specific fluorescence detection. A spectroscopic approach and a blind source separation method are proposed to unmix multiple fluorescence spectra and remove autofluorescence.
