Results While the overall project is the sorting of cargos on origami, we expected verification of all of the mechanisms would take longer than one summer. Therefore, this summer was spent verifying two aspects of the project: Verifying that the proposed mechanisms work when the strands are free-floating in solution (i.e. not bound to origami). Verifying that the random walking mechanism works as intended on origami. Verification of Overall Mechanisms in Solution Gel Verification Main article: Gel Verification All of the essential mechanisms in our system were verified in solution using polyacrylamide gel electrophoresis. These mechanisms include: walker-track binding, triggering the walker, walking from one track to another, picking up cargo, walking while carrying cargo, triggering the cargo goal, dropping off cargo, and irreversibly walking from tracks to the walker goal. We are fairly confident that all of these mechanisms work as expected in solution, with a few mysteries that do not seem to interfere with the overall behavior of the system (see Gel Verification).
