对于未来的微米和纳米技术，微型化，功能化和集成器件的制造是必不可少的。在本文中，一个自下而上的战略，使复杂的微系统的制造仅使用光学方法的基础上的组装技术。螺纹连接被转移到微米范围内，用于组装螺钉和螺母形状的微型元件。通过双光子聚合进行微立体光刻，并且制造微结构，随后在全息光镊装置中使用光学力捕获、移动和拧紧在一起。联锁微组件的设计和建设，并验证了稳定和可释放的联合形式的主要重点，本文。该组装技术还应用于微流体系统，以使得能够在微流体芯片上泵送或混合流体。这种策略不仅可以组装微组件，还可以组合不同的材料和特征，形成复杂的混合微系统。
For future micro- and nanotechnologies, the manufacturing of miniaturized, functionalized, and integrated devices is indispensable. In this paper, an assembly technique based on a bottom-up strategy that enables the manufacturing of complex microsystems using only optical methods is presented. A screw connection is transferred to the micrometer range and used to assemble screw- and nut-shaped microcomponents. Micro-stereolithography is performed by means of two-photon polymerization, and microstructures are fabricated and subsequently trapped, moved, and screwed together using optical forces in a holographic optical tweezer set-up. The design and construction of interlocking microcomponents and the verification of a stable and releasable joint form the main focus of this paper. The assembly technique is also applied to a microfluidic system to enable the pumping or intermixing of fluids on a microfluidic chip. This strategy not only enables the assembly of microcomponents but also the combination of different materials and features to form complex hybrid microsystems.
