A highly sensitive electrochemical immunosensor based on a g-C₃N₄/MgO nanocomposite for ultrasensitive detection of CYFRA21-1
A sensitive and label-free electrochemical immunosensor based on a g-C₃N₄/MgO nanocomposite-modified electrode for the selective detection of CYFRA21-1 has great promise for clinical diagnosis and point-of-care detection of lung cancer biomarkers because of its affordability, simplicity, and sensitivity.
