Project Design Project Overview Our goal for the summer is to develop a system that autonomously sorts DNA tagged structures. Our base system involves randomly placed DNA tagged cargo on a rectangular DNA origami [1]. One edge of the origami is tagged with goal strands, and the rest of the origami is filled with track strands. The origami is then populated with random walkers that traverse the origami, picking up cargo and dropping them off at the goal. The motion of the walker and cargos will be examined by atomic force microscopy imaging. Bulk behavior of the system, kinetics of walking, and mechanisms of cargo picking up, and cargo dropping off will be analyzed by SPEX experiment. Main article: Project Overview References [1] Paul W.
