Before revision:  These experiments also provide crucial insights into how dynamic state changes may affect biological function, for example, during an action potential or during therapeutic use of acoustic impulses in the form of ultrasound or shock waves .
After revision:  Corresponding changes in emission spectrum of the dye were observed simultaneously across two different wavelengths at sub-microsecond resolution. The experiments show that changes in the emission spectrum and hence the fluctuations of the solvation shell are given by the thermodynamic state change during the process. Therefore, the study suggests that acoustic fields can potentially modulate the kinetics of channels and proteins embedded in lipid membranes by controlling the state dependent fluctuations .
