The journal version of our paper on Turning Machines is publihed, and aailbile for free by Open Access.
As the paper title says, Turning Machines are a simple algorithmic model for molecular robotics.
The model is designed to be simple enough to be implementable in the lab, yet programmable. Execution of an algorithm corresponds to folding a shape. The system starts out as a straight-line chain of monomers, and when programmed (or given input), the system folds into a shape. A single initial line of monomers is capable of folding many shapes, depending on how its programmed, just like how your computer performs different actions depending on the input you give.
