  Highly specific spatiotemporal interactions between cognate molecular
partners essentially sustain all biochemical transactions in the living matter.
That such an exquisite level of accuracy may result from encountering forces
solely driven by thermal diffusive processes is unlikely. Here we propose a yet
unexplored strategy to experimentally tackle the long-standing question of a
possibly active recruitment at a distance of cognate partners of biomolecular
reactions via the action of resonant electrodynamic interactions. We considered
two simplified models for a preliminary feasibility investigation of the
devised methodology. By taking advantage of advanced experimental techniques
nowadays available, we propose to measure the characteristic encounter time
scales of dually-interacting biopartners and to compare them with theoretical
predictions worked out both in the presence or absence of putative long-range
electromagnetic forces.
