Opto-Mechanical Coupling in Interfaces under Static and Propagative Conditions and Its Biological Implications
Figure 5
Opto-Mechanical State diagram.
The surface can be broadly divided in to three regions as liquid expanded (LE), liquid expanded – liquid condensed (LE-LC) and liquid condensed (LC) region. Slopes along the A axis represent compressibility and area fluctuations, while slopes along I characterize opto-mechanical susceptibility and fluctuations in Intensity, respectively. The transition region (LE-LC) moves to higher pressure, lower area and lower intensity with increasing temperature. The curves represent real data acquired using DPPC-NBD.
