L-glutamine's role in cancer metabolism makes it a more versatile biomarker for cancer detection. A plasmonic fiberoptic absorption biosensor (P-FAB), an emerging technology that utilizes a compact U-shaped optical fiber with an enhanced evanescent field and plasmonic labels to give rise to an ultra-high analyte detection sensitivity, was employed to detect L-Glutamine (L-Gln) as a biomarker using a competitive immunoassay for early cancer detection.
