尽管我们生活在三维(3D)的世界中,而宏观的工程是3D,但常规的次数量表工程本质上是二维的(2D)。在这里,我们审查了在过去的二十年中开发的策略这篇综述的重点是自我组装的策略,特别是以生物学启发的,更确定的形式称为自我折叠的方法。将这种自组装方法与其他3D制造范式进行了比较,并讨论了其优点和缺点。
Despite the fact that we live in a three-dimensional (3D) world and macroscale engineering is 3D, conventional sub-mm scale engineering is inherently two-dimensional (2D). New fabrication and patterning strategies are needed to enable truly three-dimensionally-engineered structures at small size scales. Here, we review strategies that have been developed over the last two decades that seek to enable such millimeter to nanoscale 3D fabrication and patterning. A focus of this review is the strategy of self-assembly, specifically in a biologically inspired, more deterministic form known as self-folding. Self-folding methods can leverage the strengths of lithography to enable the construction of precisely patterned 3D structures and “smart” components. This self-assembling approach is compared with other 3D fabrication paradigms, and its advantages and disadvantages are discussed.
