The Electrified Interface

Abstract

Earlier, it was discussed that while homogeneous systems are more easily described, many cellular processes are heterogeneous. Because so many processes occur that require the exchange of components across at least one phase, it is extremely valuable for the biological scientist to have an understanding of the forces and structures that act in the zone of transition between phases. When different phases come in contact with each other, an interface between them occurs. This interface is a surface, and the properties of a surface are different from those of either of the phases responsible for creating it. Additionally, the changeover between phases is never instantaneously abrupt, but instead there is a zone of transition extending from the surface for a finite distance into the bulk of each of the phases where the properties are representative of neither bulk phase. The surface and the regions immediately adjacent are termed the interphase, a very useful distinction. The properties of interphases will be the the subsequent focus of this section.
