Lay Summary (Englisch)

Lead
Lay summary
A challenge in research at the micro- and nanoscales is that 3D structures and devices at the appropriate scales are comparatively difficult to produce.Recently, however, special laser writers have become available which function as standalone production facilities, enabling the quick and cost effective manufacture of fully design-controlled 3D structures at the micrometer scale and smaller.The acquired lithography system allows for the production of arbitrary 3D micro- and nano-structures with feature sizes less than 200 nanometer and a design volume of more than 300 micrometer^3. Different materials can be processed ranging from standard photoresists to ceramics and metals using various replication techniques.The first research projects to make use of this facility will includeoParticle and aerosol deposition in the alveolar section of the lungoSelf-Regulation of red blood cell transport in capillaryoOptimization of implant biocompatibility using nano-structured surfacesoCreation of nano-porous materials for drug-delivery

Abstract

It is proposed to acquire a desktop 3D laser nanolithography system for use in different research projects ongoing in the Mechanical Engineering Department (D-MAVT) of ETH Zurich.Such a lithography system allows for the production of arbitrary 3D micro- and nanostructures with feature sizes less than 200 nm and a design volume of more than 300 micron^3. Different materials are available ranging from standard photoresists to ceramics and metals using various replication techniques.Most importantly, the proposed laser writer is operated in a “rapid prototyping” fashion, using standard CAD design procedures to reduce the overall manufacturing effort to a minimum. In contrast to the selective purchase of custom manufactured micro- and nanostructures, the direct access to a laser lithography system will allow for more flexibility in the design and shorter development cycles.The research projects discussed in this proposal which have an immediate use for such a machine are•The investigation of particle and aerosol deposition in the alveolar section of the lung (Prof. Rösgen, Institute of Fluid Dynamics, ETHZ)•The study of self-Regulation of red blood cell transport in capillary networks (Profs. Rösgen & Jenny, Institute of Fluid Dynamics, ETHZ)•Electrowetting based inkjet for printing of 2D and 3D nano-scale structures (Prof. Poulikakos, Lab. of Thermodynamics in Emerging Technologies, Inst. of Energy Technology, ETHZ)•Thin polymer film-based micro-scale direct methanol fuel cell (µDMFC) (Prof. Poulikakos, Lab. of Thermody-namics in Emerging Technologies, Inst. of Energy Technology, ETHZ)•Membraneless, high sensitivity pressure sensor for integration in disposable and flexible lab-on-chip systems (Prof. Poulikakos, Lab. of Thermodynamics in Emerging Technologies, Inst. of Energy Technology, ETHZ)•Optimization of vascular implant biocompatibility through nano-structured surfaces (Prof. Poulikakos, Lab. of Thermodynamics in Emerging Technologies, Inst. of Energy Technology, ETHZ)•Creation of nano-porous materials for drug-delivery applications (Prof. Nelson, Multiscale Robotics Lab, Inst. of Robotics and Intelligent Systems, ETHZ)At present, the proposed 3D laser writer would be the first of its kind in Switzerland and one of the few systems worldwide set up as a turnkey production tool.Among the (few) commercial laser systems available, a system offered by Nanoscribe GmbH (Karlsruhe, Germany) was identified as the most versatile device.The projected cost will be € 290’000 at current conditions.
