Improved immunoassay sensitivity and specificity using single-molecule colocalization

A major challenge of enzyme-linked immunosorbent assays is discriminating true signal from non-specific binding. Here the authors present a Single-Molecule Colocalization Assay (SiMCA) which eliminates such effects, enabling reproducible detection of picomolar protein concentrations.
