| Two dimensional dispersions of lipid membrane derivatized silica beads exhibit colloidal phase transitions that are governed by membrane surface interactions. The collective phase behavior serves as a cooperative amplifier that produces a readily detectable response from small perturbations of the membrane surface. Using direct optical imaging, we observe multiple near-equilibrium phases and resolve transitions induced by molecular events on the membrane surface. |
