Cells, Gels And Mechanics

Abstract
The cell is a gel. Yet, gel-like features of the cytoplasm have hardly been
exploited for engineering design. If the cell is a gel, then a logical approach to
the understanding of cell function may be through an understanding of gel
function. Great strides have been made recently in understanding the principles
of gel dynamics. It has become clear that a central mechanism in biology is the
polymer-gel phase-transition — a major structural change prompted by a subtle
change of environment. Phase-transitions are capable of doing work, and such
mechanisms could be responsible for much of the work of the cell. Here, we
consider this approach. We set up a polymer-gel-based foundation for cell
function, and explore the extent to which this foundation explains how the cell
goes about its business, with an eye toward exploiting these principles for
engineering design.
