Multistate part for mesoscale self-assembly

Algorithmic self-assembly is defined as a process of spontaneous formation of several different types of elements into algorithmically defined stable structure. However, in the process of algorithmic self-assembly, it is important to control the concentrations of each element. In this paper, we propose a novel design of a multistate part for algorithmic self-assembly. By virtue of its multistate, the ratio of different parts is always maintained at constant. Preliminary self-assembly experiments showed feasibility of the multistate part.
