“…Therefore, in the case of interest, the imprinting temperature must be higher than the glass transition temperature (T Impr > T g ). There are articles [53,54] describing the processes in which intermediate IPS stamps were prepared at temperatures well in excess of the glass transition temperature T Impr ≥ 160 • C and at pressures P Impr ≥ 40 bar; under such conditions, it was possible to reach a better filling of the master-stamp micro-and nanorelief with the polymer. In the present work, it was required not only to create a deep (>10 µm) imprint in the IPS but, also, to press a dense array of metal strips into the substrate.…”

“…Addition of a second resonator layer expands the capabilities in controlling the polarization and intensity of transmitted radiation thanks to the increased number of elements and increased surface fill factor, as well as due to the ability to fabricate structures with different separations between the layers. Two-and multi-layer resonator systems [26,27,31,[52][53][54][58][59][60] are known to be efficient converters of electromagnetic radiation. Additional layers into the system can lead to various phenomena such as Fabry-Perot resonances, and the shift and splitting of fundamental resonances due to the near-field interaction.…”

An original hybrid method for three-dimensional (3D) shaping of micro- and nanostructures by direct imprinting of lithographically patterned metal 2D-elements on a polymer substrate is proposed. The technological features of the method are demonstrated by transforming Au micro/nanostrip arrays into 3D half-turn helices. The metasurface formed by an array of 3D half-turn Au microhelices in the surface layer of a polymer substrate rotates the polarization plane of transmitted 3 THz radiation through an angle in excess of 50°. Both experimentally and numerically, it is established that the metasurface permits to control the state of polarization and the intensity of transmitted linearly polarized THz radiation using half-wavelength and guided-mode resonances as well as diffraction effects. The proposed approach enables the fabrication of double-layer arrays of half-helices, designed for infrared metasurfaces, from 80 nm wide Au nanostrips. These studies not only pave the way towards the fabrication of large-area chiral metamaterials but, also, open a new avenue in the development of 3D micro/nanostructures for other applications.

“…mask-based patterning in the ultraviolet (UV) or extreme ultraviolet (EUV) spectral range; or nanoimprint lithography (NIL) is a better choice. Whereas EBL is still needed to create the mask for (E)UV lithography or the master stamp for NIL [70,71], the modular network design offers ways to employ these technologies both for the fabrication of multiple identical networks and individual modular networks.…”

Network-based biocomputation (NBC) is an alternative, parallel computation approach that potentially can solve technologically important, combinatorial problems with much lower energy consumption than electronic processors. In NBC, a combinatorial problem is encoded into a physical, nanofabricated network. The problem is solved by biological agents (such as cytoskeletal filaments driven by molecular motors) that explore all possible pathways through the network in a massively parallel and highly energy-efficient manner. Whereas there is currently a rapid development in the size and types of problems that can be solved by NBC in proof-of-principle experiments, significant challenges still need to be overcome before NBC can be scaled up to fill a technological niche and reach an industrial level of manufacturing. Here, we provide a Roadmap that identifies key scientific and technological needs. Specifically, we identify technology benchmarks that need to be reached or overcome, as well as possible solutions for how to achieve this. These include methods for large-scale production of nanoscale physical networks, for dynamically changing pathways in these networks, for encoding information onto biological agents, for single-molecule read-out technology, as well as the integration of each of these approaches in large-scale production. We also introduce figures of merit that help analyze the scalability of various types of NBC networks and we use these to evaluate scenarios for major technological impact of NBC. A major milestone for NBC will be to increase parallelization to a point where the technology is able to outperform the current run time of electronic processors. If this can be achieved, NBC would offer a drastic advantage in terms of orders of magnitude lower energy consumption. In addition, the fundamentally different architecture of NBC compared to conventional electronic computers may make it more advantageous to use NBC to solve certain types of problems and instances that are easy to parallelize. To achieve these objectives, the purpose of this Roadmap is to identify pre-competitive research domains, enabling cooperation between industry, institutes and universities for sharing R&D efforts and reduction of development cost and time.

Physical requirements for scaling up network-based biocomputation

The high energy consumption of electronic data processors, together with physical challenges limiting their further improvement, has triggered intensive interest in alternative computation paradigms. Here we focus on network-based biocomputation (NBC), a massively parallel approach that benefits from the energy efficiency of biological agents, such as molecular motors or bacteria, and their availability in large numbers. We analyse and define the fundamental requirements that need to be fulfilled to scale up NBC computers to become a viable technology that can solve large NP-complete problem instances faster or with less energy consumption than electronic computers. Our work can serve as a guide for further efforts to contribute to elements of future NBC devices, and as the theoretical basis for a detailed NBC roadmap.
