“…The microtubular cavity actually provides 3D confinement of the light: the ring‐like cross section is a whispering‐gallery type cavity while the propagation of light along the axis direction produces axial mode, like the case in Fabry–Perot cavity . For a rolled‐up microtube with diameter of ≈20 µm made from nanocrystalline diamond nanomembrane (panel (i) of Figure b), the photoluminescence spectrum (red line in panel (ii) of Figure b) shows an obvious intensity modulation due to emitted light from color center coupled to the whispering gallery modes of the microtube . The quality‐factor of the microtube is determined to be more than one thousand and the enhancement in the photoluminescence compared with flat nanomembrane was attributed to the light‐trapping effect in the tubular geometry .…”

“…On the other hand, if the internal strain and/or thickness of the nanomembrane are regulated, unique 3D structures can be construct via a self‐assembly process. Panel (ii) of Figure c shows the morphology of a self‐rolled tube‐in‐tube structure by thinning nanomembrane locally before releasing and rolling . The methodologies and applications of these interesting 3D structures constructed by assembly and self‐assembly processes will be discussed in detail respectively in the following sections, Sections and .…”

“…The 2D precursor then self‐assembled into a cube under the influence of the surface tension of the molten solder (right panel of Figure d) . In the left panel of Figure e, a hockey‐stick‐shaped nanomembrane is patterned by reactive ion etching, and the internal strain therein makes it roll/bend into a helical structure (right panel of Figure e) …”

Nanoscience and nanotechnology offer great opportunities and challenges in both fundamental research and practical applications, which require precise control of building blocks with micro/nanoscale resolution in both individual and mass-production ways. The recent and intensive nanotechnology development gives birth to a new focus on nanomembrane materials, which are defined as structures with thickness limited to about one to several hundred nanometers and with much larger (typically at least two orders of magnitude larger, or even macroscopic scale) lateral dimensions. Nanomembranes can be readily processed in an accurate manner and integrated into functional devices and systems. In this Review, a nanotechnology perspective of nanomembranes is provided, with examples of science and applications in semiconductor, metal, insulator, polymer, and composite materials. Assisted assembly of nanomembranes leads to wrinkled/buckled geometries for flexible electronics and stacked structures for applications in photonics and thermoelectrics. Inspired by kirigami/origami, self-assembled 3D structures are constructed via strain engineering. Many advanced materials have begun to be explored in the format of nanomembranes and extend to biomimetic and 2D materials for various applications. Nanomembranes, as a new type of nanomaterials, allow nanotechnology in a controllable and precise way for practical applications and promise great potential for future nanorelated products.

Inspired by the machines that have changed the world through their autonomous functions, scientists have focused their attention on performing similar functions at the micro/nanoscale. The motility of these micro/nanomachines (micro/nanomotors) offers enormous opportunities for cargo delivery, biodetection, and environmental and biomedical applications. Among the various geometries of micro/nanomotors, a tubular shape provides asymmetric inner and outer surfaces, where the inner wall hosts chemical reactions that supply the moving power and the outer wall can be modified for specific chemical and biological functions. This review describes the concept of tubular micro/nanomotors, including their basic principles, fabrication methods and control over their motion. With the assistance of catalytic reactions, tubular micro/nanomotors can generate a powerful thrust force to navigate in complex natural and in vitro environments. Modification of the tubular micro/nanomotors allows the motors to capture, transport, and release selected cargos on demand. In addition, their application in sensing and decontamination benefits from their collection behavior and self‐mixing effect. Furthermore, noncatalytic reaction‐driven tubular micro/nanomotors, such as redox‐based and biohybrid tubular micro/nanomotors, provide new possibilities for practical in vivo applications. The state‐of‐the‐art tubular micro/nanomotors could offer a promising platform for various applications, e.g., lab‐on‐chip devices and in vivo theranostics.
