Modulation-frequency Encoding/Decoding for Parallel Detection in Biophotonic Sensing

Not Accessible

Your library or personal account may give you access

Abstract

Fluorescence from different emitters (labeled biomolecules) with distinct absorption wavelengths is encoded by uniquely modulating each excitation beam. Detection by an ultrasensitive, albeit color-blind photomultiplier and subsequent Fourier analysis reveals the origin of each signal.
