This thesis work examines the scalability of an imprinting stage utilizing parallel self-aligning mechanisms in a DNA combing and imprinting (DCl) process. Scalability is vital in developing efficient, low-cost and high-yield manufacturing processes, and improving the scalability of the DCI imprinting process will benefit biomedical research by enabling the affordable and scalable production of micro/nanoarrays for drug discovery, protein isolation, nanofluidics, and other applications. Previous work on the DCI process has primarily focused on the mechanics of the imprinting process rather than scale, and misalignments between the stamp and slide surfaces make it difficult to increase the scale without drastically increasing the complexity of the system, particularly when a 3 degree of freedom positioning device is used. Herein, a 1 degree of motion stage with 3 independent, passive self-aligning mechanisms is demonstrated to achieve high performance at 3 times the scale of previous devices. The influence of kinematic coupling repeatability, parallelism, and linear motion parasitics on the performance of the imprinting device was identified, and the device's performance was measured. The repeatability of the kinematic couplings and the magnitude of the parasitic motions were found to exceed the gage resolution of 12.7 [mu]m, and the initial parallelism variation of the stage is less than 140 [mu]m. A mathematical model to quantify the scalability of the device was also developed by examining its ability to handle misalignments in the stage, stamp, and slide alignment. Analysis with the model demonstrated the ability of the device to accommodate maximum misalignments ranging from 3.9° to 9.3°, confirming the minimal performance-scale tradeoff of a 1 degree of freedom motion stage. Through this analysis, this thesis demonstrates the effectiveness of parallel, self-aligning stamp mechanisms in a scalable DCI process, and provides a framework for future development of scalable imprinting stages. by John J.
