(A) Hemagglutinin H5 immunosensor based on a SAM of 4,4′-thiobisbenzenethiol carrying single chain variable fragments (scFv) of antibodies as probes. Reprinted from [31], Copyright 2016, with permission from Elsevier; (B) Schematic representation of a scFv fragment. A scFv fragment makes 25 kDa and corresponds to the VH + VL domains; it is the smallest fragment that holds a complete binding site of an antibody and therefore provides its specificity.
