“…This important demonstration stimulated intensive studies by other researchers 85,93 , and versatile 3D nanostructures were manufactured ( Fig. 5f-k) 80,82,94 , among which the first photonic application was demonstrated by Cui et al in 2015 through folding of a vertical split-ring resonator (SRR) array on a metallic hole array 80 . However, most of these nanostructures were fabricated by local irradiation of specific areas, which induced zero curvature except at the folding regions, 55 .…”

Advanced kirigami/origami provides an automated technique for modulating the mechanical, electrical, magnetic and optical properties of existing materials, with remarkable flexibility, diversity, functionality, generality, and reconfigurability. In this paper, we review the latest progress in kirigami/origami on the microscale/nanoscale as a new platform for advanced 3D microfabrication/nanofabrication. Various stimuli of kirigami/origami, including capillary forces, residual stress, mechanical stress, responsive forces, and focussed-ion-beam irradiation-induced stress, are introduced in the microscale/nanoscale region. These stimuli enable direct 2D-to-3D transformations through folding, bending, and twisting of microstructures/nanostructures, with which the occupied spatial volume can vary by several orders of magnitude compared to the 2D precursors. As an instant and direct method, ion-beam irradiation-based tree-type and close-loop nano-kirigami is highlighted in particular. The progress in microscale/nanoscale kirigami/ origami for reshaping the emerging 2D materials, as well as the potential for biological, optical and reconfigurable applications, is briefly discussed. With the unprecedented physical characteristics and applicable functionalities generated by kirigami/origami, a wide range of applications in the fields of optics, physics, biology, chemistry and engineering can be envisioned.

“…The lateral dimensions of their filament structures, however, were quite small, about 25 µm × 3 mm. The production technologies for pure metal freestanding nanomembranes evolved over years and Jia et al reported in 2019 a routine production of large-area (up to 75 cm 2 ) freestanding gold nanomembranes with arrays of nanoholes and with thickness values as low as 50 nm [61].…”

Nanomembranes are the principal building block of basically all living organisms, and without them life as we know it would not be possible. Yet in spite of their ubiquity, for a long time their artificial counterparts have mostly been overlooked in mainstream microsystem and nanosystem technologies, being a niche topic at best, instead of holding their rightful position as one of the basic structures in such systems. Synthetic biomimetic nanomembranes are essential in a vast number of seemingly disparate fields, including separation science and technology, sensing technology, environmental protection, renewable energy, process industry, life sciences and biomedicine. In this study, we review the possibilities for the synthesis of inorganic, organic and hybrid nanomembranes mimicking and in some way surpassing living structures, consider their main properties of interest, give a short overview of possible pathways for their enhancement through multifunctionalization, and summarize some of their numerous applications reported to date, with a focus on recent findings. It is our aim to stress the role of functionalized synthetic biomimetic nanomembranes within the context of modern nanoscience and nanotechnologies. We hope to highlight the importance of the topic, as well as to stress its great applicability potentials in many facets of human life.

NanoRobotic Structures with Embedded Actuation via Ion Induced Folding

et al. 2021

4D structures are tridimensional structures with time‐varying abilities that provide high versatility, sophisticated designs, and a broad spectrum of actuation and sensing possibilities. The downsizing of these structures below 100 μm opens up exceptional opportunities for many disciplines, including photonics, acoustics, medicine, and nanorobotics. However, it requires a paradigm shift in manufacturing methods, especially for dynamic structures. A novel fabrication method based on ion‐induced folding of planar multilayer structures embedding their actuation is proposed—the planar structures are fabricated in bulk through batch microfabrication techniques. Programmable and accurate bidirectional foldings (−70° − +90°) of Silica/Chromium/Aluminium (SiO2/Cr/Al) multilayer structures are modeled, experimentally demonstrated then applied to embedded electrothermal actuation of controllable and dynamic 4D nanorobotic structures. The method is used to produce high‐performances case‐study grippers for nanorobotic applications in confined environments. Once folded, a gripping task at the nano‐scale is demonstrated. The proposed fabrication method is suitable for creating small‐scale 4D systems for nanorobotics, medical devices, and tunable metamaterials, where rapid folding and enhanced dynamic control are required.
