Studying and Simulating the Three-Dimensional Arrangement of Droplets

We present some work in progress on the development of a probabilistic chemical compiler, being able to make a plan of how to create a three-dimensional agglomeration of artificial hierarchical cellular constructs. These programmable discrete units offer a wide variety of technical innovations, like a portable biochemical laboratory being able to e.g. produce macromolecular medicine on demand, and of scientific investigations, like contributions to questions regarding the origin of life. This paper focuses on one specific issue of developing such a compiler, namely the problem of simulating the experimentally observed spatial transition from an originally one-dimensional lineup of droplets into a three-dimensional, almost spherical arrangement, in which the droplets form a network via bilayers connecting them and in which they are contained within some outer hull. The network created by the bilayers allows the droplets to “communicate” (like agents in a multi agent system) with each other and to exchange chemicals contained within them, thus enabling a complex successive biochemical reaction scheme.
