  In this article we highlight chemotaxis (cellular movement) as a rich source
of potential engineering applications and computational models, highlighting
current research and possible future work. We first give a brief description of
the biological mechanism, before describing recent work on modelling it in
silico. We then propose a methodology for extending existing models and their
possible application as a fundamental tool in engineering cellular pattern
formation. We discuss possible engineering applications of human-defined cell
patterns, as well as the potential for using abstract models of chemotaxis for
generalised computation, before concluding with a brief discussion of future
challenges and opportunities in this field.
