Before revision:  subjected to broadband pressure impulses of the order of 1Mpa peak amplitude and pulse width of less than 10 \mu s. The response is quantified in terms of the shift in fluorescence spectra using a ratiometric technique . Based on the fluctuation dissipation theorem applied to a coupled membrane-fluorophore system,
After revision:  subjected to broadband pressure impulses of the order of 1Mpa peak amplitude and pulse width of less than 10 \mu Physical and chemical changes in biological interfaces can be quantified by corresponding changes in the thermodynamic state of the interface . Based on the fluctuation dissipation theorem applied to a coupled membrane-fluorophore system,
