So it ought to be possible to test for the presence of a certain antigen on a surface by dragging a suitable antibody over it, and seeing if it gets stuck—going fishing, in effect, on a molecular scale.

As the tip continued its movement across the surface, the antibody was snapped off the antigen and dragged along until it hit another receptive site.
