自组装是较小的组件自主组装形成更大，更复杂的结构的过程。自组装的应用领域之一是复杂纳米结构的工程和生产。最近，研究人员提出了一种新的折叠模型，称为oritatami模型（OM），它模拟了共转录自组装，基于折叠分子最终形状的动力学。Oritatami系统（OS）中的纳米结构由晶格上的一系列珠子和相互作用表示。我们提出了一种方法来设计一个通用的操作系统，我们称之为GEOS，构造一个给定的几何结构。其主要思想是为目标结构中每一对可能的相邻点设计小型模块化操作系统，我们称之为铰链。一旦目标结构的形状填充曲线准备好了，我们就构建一个适当的主结构，该主结构通过一系列铰链跟随曲线。我们建立了一个通用的指导方针设计的GEOS，并提出了两个GEOS。
Self-assembly is the process where smaller components autonomously assemble to form a larger and more complex structure. One of the application areas of self-assembly is engineering and production of complicated nanostructures. Recently, researchers proposed a new folding model called the oritatami model (OM) that simulates the cotranscriptional self-assembly, based on the kinetics on the final shape of folded molecules. Nanostructures in oritatami system (OS) are represented by a sequence of beads and interactions on the lattice. We propose a method to design a general OS, which we call GEOS, that constructs a given geometric structure. The main idea is to design small modular OSs, which we call hinges, for every possible pair of adjacent points in the target structure. Once a shape filling curve for the target structure is ready, we construct an appropriate primary structure that follows the curve by a sequence of hinges. We establish generalized guidelines on designing a GEOS, and propose two GEOSs.
