In the present project, the development of a novel technology for the fabrication of microstructures containing metal and dielectric nanoparticles as elementary building blocks is proposed. This technology is based on a combination of femtosecond laser-induced transfer (LIT) of metallic and dielectric particles and two-photon polymerization (2PP) techniques. The controllable fabrication of high quality spherical metal micro- and nanoparticles with a minimum size below 200 nm and a maximum size above 1 μm can be realized using the LIT approach recently demonstrated in our group. These particles can be deposited onto different substrates and into arbitrary 2D and 3D polymeric microstructures. In combination with the two-photon polymerization technique the LIT approach provides unique possibilities for the fabrication of micro- and nanostructures containing metal and dielectric nanoparticles as elementary building blocks. Experimental and theoretical study of the fabricated structures proposed in this project will allow realization of novel 2D and 3D metamaterials and nanophotonic components. This new technology can also find interesting applications in microfluidics, sensors, photovoltaics, and biomedicine.

在本项目中，提出了一种用于制造包含金属和介电纳米颗粒作为基本构建块的微结构的新技术的开发。该技术基于飞秒激光诱导金属和介电颗粒转移（LIT）和双光子聚合（2PP）技术的组合。利用本课题组最近提出的LIT方法可以实现最小尺寸小于200 nm、最大尺寸大于1 μm的高质量球形金属微米和纳米颗粒的可控制备。这些颗粒可以沉积在不同的基底上，并形成任意的2D和3D聚合物微结构。结合双光子聚合技术，LIT方法为制造含有金属和介电纳米颗粒作为基本构建块的微米和纳米结构提供了独特的可能性。在这个项目中提出的制造结构的实验和理论研究将允许实现新的2D和3D超材料和纳米光子组件。这项新技术也可以在微流体、传感器、光电子学和生物医学中找到有趣的应用。
