An electric birefringence study was carried out on aqueous suspensions of the purple membrane of Halobacterium halobium. In addition to the characterization of both native and modified membrane samples, the dependence of electric birefringence on p H and ionic strength was also investigated. The res

โฆ Synopsis
The permanent dipole moment and electric polarizability of purple membrane have been found using electrooptic methods. Comparison of the results with those for other inorganic or biological disperse particles as well as the observed effects and dynamics for a large range of applied electric field strengths support the proposal of a surface origin for the electric polarizability of purple membrane.
