Long-range electrodynamic interactions between proteins assessed by THz spectroscopy

We experimentally demonstrate, for the first time, the activation of long-range attractive electrodynamic forces between proteins by means of THz spectroscopy. Our experimental work provides a proof of principle of out-of-equilibrium collective oscillations and the related activation of dipole-dipole electrodynamic intermolecular forces. It paves the way for exploring the potential role of electrodynamic intermolecular forces in living matter.
