A bio-conjugated 2D photonic crystal hydrogel-based immunoassay for glycocholic acid.
Hepatocellular carcinoma (HCC) remains a leading cause of cancer-related mortality worldwide, underscoring an urgent need for reliable point-of-care testing (POCT) tools. Glycocholic acid (GCA), owing to its high specificity and sensitivity, has been recognised as a promising biomarker for HCC. Nevertheless, current GC...
