This EArly-concept Grant for Exploratory Research (EAGER) award provides funding to develop an innovative 3-D additive manufacturing process capable of producing uniform metal and polymer features with nanometer resolution for applications in optics, photonics, biomaterials and other areas. Here, we propose to combine the patterning resolution and scaling benefits provided by the recently developed optical trap assisted nanopatterning method with the 3-D additive capabilities of ultrafast multiphoton polymerization processing. However in order to achieve this goal, it is necessary to attain a deeper understanding of these processes and demonstrate the feasibility of such a combined approach. To this end, this proposal will focus on experimentally and numerically probing fundamental proof?]of?]principle questions related to the compatibility of ultrafast laser processing and polymer precursor solutions with optically trapped microspheres, and the ability to polymerize precursor solutions in the vicinity of microspheres without contamination or redeposition. Numerical studies will include finite difference time domain simulations for optical propagation through the liquid solution and polystyrene microspheres. Whereas, experiments will use both in situ imaging during laser processing and ex situ characterization to identify the material response.If successful, this research will have a profound impact on a number of diverse application areas where multiscale and multifunctional 3-D architectures are needed to advance functionality, such as in photonic materials, optoelectronics, microfluidics, tissue engineering, etc. Broad dissemination in these areas through publications and international presentations will ensure researchers gain widespread benefit from our studies. But perhaps more importantly, the success of this research will provide a demonstration of feasibility that is necessary to secure funding through traditional vehicles in order to further develop this potentially transformative materials processing approach. Finally, we envision this research as a seed for an international collaboration between researchers at Princeton and University of Erlangen-Nurenberg, School of Advanced Optical Technologies (UEN-SAOT) in Germany for 3-D laser based manufacturing. To this end, funds have been allocated to support the travel to UEN-SAOT where the PIs will help train other researchers and students in this developing technology.

这一探索性研究（EAGER）早期概念补助金为开发一种创新的3d增材制造工艺提供了资金，该工艺能够生产纳米分辨率的均匀金属和聚合物特征，用于光学、光子学、生物材料和其他领域。在这里，我们建议将最近开发的光学陷阱辅助纳米图像化方法提供的图像化分辨率和缩放优势与超快多光子聚合处理的三维添加能力相结合。然而，为了实现这一目标，有必要对这些过程有更深入的了解，并证明这种综合方法的可行性。为此，本提案将集中于实验和数值探索的基本证明？与超快激光加工和聚合物前驱体溶液与光学捕获微球的相容性有关的原理问题，以及在微球附近聚合前驱体溶液而不污染或再沉积的能力。数值研究将包括光通过液体溶液和聚苯乙烯微球传播的时域有限差分模拟。然而，实验将在激光加工过程中使用原位成像和非原位表征来识别材料响应。如果成功，这项研究将对许多不同的应用领域产生深远的影响，这些领域需要多尺度和多功能的3d架构来推进功能，如光子材料、光电子、微流体、组织工程等。通过出版物和国际演讲在这些领域的广泛传播将确保研究人员从我们的研究中获得广泛的利益。但也许更重要的是，这项研究的成功将提供可行性证明，这是通过传统车辆获得资金的必要条件，以便进一步发展这种潜在的变革性材料加工方法。最后，我们设想这项研究将成为普林斯顿大学和德国埃尔兰根-纽伦堡大学先进光学技术学院（un - saot）的研究人员在3d激光制造方面进行国际合作的种子。为此，已拨出资金支持前往un - saot的旅行，在那里，pi将帮助培训其他研究人员和学生使用这项正在开发的技术。
