Mathematical Analysis of Artificial Enzymatically Active Membranes.

Abstract

The systems described in this report are immobilized enzyme membranes, produced and experimentally studied by D. Thomas and his group. The concentrations in these artificial membranes are governed by the interaction of diffusion and reaction, and they may have behaviors characteristic of dissipative structures: hysteresis (related to the existence of multiple stable steady states), oscillations, wave front propagation and pattern formation. Since analogous phenomena exist in (much more complex.) living systems (short-term memory, biological clocks, transmission of signals, morphogenesis) it is interesting to study, in a well-defined context, the interaction of diffusion and enzyme reaction.
