TAILORED IMAGING AND SENSING TECHNOLOGIES ENABLED BY 3D RAPID MICRO- TO NANO-FABRICATION

Micro- to nano-scale additive manufacturing has enabled the realization of 3D microstructures at sub-micron resolution for complex miniaturized optical and mechanical systems. There is a growing demand for integrable technologies and miniaturization in applications from biomedical diagnostics and environmental sensing to high-precision industrial tasks. The ability to rapidly prototype facilitates the development of custom-tailored components for such specialized applications. This paper presents three case studies highlighting developments utilizing two-photon direct laser writing (TP-DLW). The aim of this work is to provide a comprehensive overview of the current state-of-the-art fabrication tool for the purpose of miniaturizing imaging and sensing technologies.
