A form of self-assembly, â??self-foldingâ? presents an alternative approach to the creation of reconfigurable, responsive materials with applications ranging from robotics to drug design. However, the complexity of interactions present in biological and engineered systems that undergo folding makes it challenging to isolate the main factors controlling their assembly and dis-assembly. Here we use computer simulations of simple, minimalistic self-foldable structures and investigate their stochastic folding process. By dynamically accessing all the microstates that lead to, or inhibit, successful folding, we show that the mechanisms by which general stochastic systems achieve their native structures can be identified and used to design rules for optimized folding propensity.
