Single-Molecule Sandwich Immunoassay for Quantification of Alpha-Fetoprotein Based on Evanescent Field-Enhanced Fluorescence Imaging

A highly sensitive immunosensor based on a gold nanopatterned chip was developed for accurate determination of alpha-fetoprotein (AFP) via total internal refection fluorescence microscopy (TIRFM). The surface of the gold nanopatterned chips was modified with dithiobis(succinimidyl propionate) and pr...
