Collective oscillations of proteins proven by terahertz spectroscopy in aqueous medium

They explain how Brownian diffusion alone does not explain the rapidity and efficiency of the bimolecular reactions inside cells, in contrast they present observations of collective oscillations in a model protein driven out-of-equilibrium by optical excitation in aqueous medium using terahertz spectroscopy, and those collective oscillations of proteins molecules have a profound significance since proteins are electrically dipolar therefore, as mentioned in another paper:

" ...the excess energy (that is, energy input minus energy losses due to dissipation) is channeled into the vibrational mode of the lowest frequency. In other words, the shape of the entire molecule is periodically deformed resulting in a “breathing” movement. In doing so the biomolecules behave as microscopic antennas that absorb the electromagnetic radiation tuned at their “breathing” (mesoscopic) oscillation frequency. But antennas at the same time absorb and re-emit electromagnetic radiation, thus, according to a theoretical prediction, these antennas (biomolecules) can attractively interact at a large distance through their oscillating near-fields, and through the emitted electromagnetic radiation, provided that these oscillations are resonant and thus, take place at the same frequency." {Credits 1}
