THz spectroscopy to probe long-range electrodynamic interactions between proteins

We have recently experimentally demonstrated, for the first time, the activation of long-range attractive electrodynamic forces between proteins by means of THz spectroscopies, supported by fluorescence cross correlation spectroscopy and numerical simulations. Our experimental work provides a proof of principle of out-of-equilibrium collective oscillations activation of dipole-dipole electrodynamic intermolecular forces. It paves the way for exploring the potential role of electrodynamic intermolecular forces in living matter.
