Single degree of freedom DNA origami analog mechanism with chiral transformation characteristics and linkage mechanism
By designing a single-degree-of-freedom DNA origami simulation mechanism, and utilizing the combination of main and secondary folding units and a non-equiangular included angle design, the problems of motion uncertainty and discontinuity in chiral switching in DNA simulation are solved. This enables continuous conversion from left-handed to right-handed chirping, exhibiting high determinism and ease of control, and is suitable for aerospace and medical engineering fields.

Abstract
This invention discloses a single-degree-of-freedom DNA origami simulation mechanism and linkage mechanism with chiral transformation characteristics. The DNA origami simulation mechanism includes: a main folding unit comprising multiple main triangles arranged along the main folding direction, with adjacent main triangles forming a quadrilateral; and at least one secondary folding unit disposed on one side of the main folding unit, including a first folding area and a second folding area. The first folding area, the second folding area, and the main triangles are sequentially connected to form a folding center. The included angle of the first folding area at the folding center is β, and the vertex angle corresponding to the side of the main triangle shared with the second folding area is α. The included angle β is greater than the included angle α. This single-degree-of-freedom DNA origami simulation mechanism and linkage mechanism with chiral transformation characteristics overcomes the deficiencies in motion uncertainty, chiral switching, and torsional continuity.
