“…This method consists of the reduction of a metal salt onto the surface of the NMs such as silica coatings or magnetic beads. The NPs produced can be varied in materials and morphology, [76] depending on the reduction conditions. Finally, the direct use of nanoparticles as nanomotors has been reported to yield significant advances within the field, NMs made of Au@Ag core-shell nanorods (NRs) have been proposed for the detection of explosives.…”

“…As an example, Figure 5B shows a schematic illustration for targeted SERS sensing of intercellular sites on HeLa cells with chemically propelled magnetic-guided NMs. [76] The sensing platform gets inside the cell membrane with the help of an induced glucose concentration increase in the culture medium to increase the cellular uptake. After internalization, the SERS nanomotors, which preserve their magnetic control, can be aggregated when desired to increase the electric field and induce a larger enhancement factor.…”

Nano/micromotors (NMs) are tiny structures capable of converting various forms of energy into mechanical motion at the micro and nanoscale. These motors operate in environments characterized by low inertia and low Reynolds numbers. The potential applications of NMs are vast, particularly in the fields of biomedicine and environmental science. One of the most intriguing developments in this field is the integration of NMs with surface‐enhanced Raman scattering (SERS) spectroscopy. SERS is a powerful analytical technique that enhances the Raman intensity of molecules, allowing for highly sensitive detection and analysis of trace amounts of substances. This integration offers highly precise and localized ultrasensing capabilities. The combination of NMs with SERS can also facilitate real‐time imaging inside living organisms. This has immense potential in chemical and cell biology and medical diagnostics and prognosis. Herein this review describes the types of NMs and their fabrication, the incorporation of plasmonic nanostructures, capable of creating strong electromagnetic fields when illuminated by light, which in turn enhances the Raman signals significantly, their applications, and their future prospects in areas such as precision medicine, environmental monitoring, and possibly even in new realms like microscale robotics and targeted therapeutics.

“…However, ITO electrodes have limited their application in flexible devices due to the poor mechanical strength of the material itself, the complexity of the preparation process, and the high cost. Recently, many conductive materials including conductive polymers, , carbon-based materials, and conductive metal-based materials have been developed as flexible alternatives to ITO, among which conductive polymers and carbon-based materials are poor in electrical conductivity, light transmission, and environmental stability. PEDOT:PSS is a typical conductive thin-film material with a variety of advantages, including high optical transparency, excellent flexibility, and superior chemical stability.…”

With the development of electronic devices toward thinner, lighter, and more flexible, the preparation of transparent electrodes for device assembly has garnered significant attention. Traditional transparent electrodes of indium tin oxides are brittle and difficult to adapt to deformations such as bending and stretching of flexible substrates. Flexible electrodes based on two-dimensional microstructures have become viable alternatives; however, the current electrode fabrication methods are complex, typically requiring the involvement of multiple machining equipment and the combination of multiple fabrication processes for machining and fabrication, and the simple, direct, and efficient integrated fabrication of electrodes is still a great challenge. Herein, an integrated manufacturing strategy for directly printing flexible multilayer composite electrodes based on an electrohydrodynamic printing process is proposed. The printing experimental system was designed. A finite element model was developed to make a preliminary selection of the parameters and the range of values affecting printing. Experiments were designed to analyze the combination of printing parameters to determine the range of applicability. The line width prediction model was used to predict the printing of structures with superior finish quality. Different printing modes were selected for different mesh electrode layers, electrode reinforcement layers, and encapsulation layers of the composite electrodes. Surface modification treatment was combined with direct printing for the direct assembly of electrodes. The electrode of finalized size 20 mm × 20 mm has good light transmission, conductivity, deformation, and mechanical stability; current efficiency and lightemitting diode (LED) light brightness before and after deformation are basically unchanged. The electrode in different bending diameters after 1000 cycles of resistance change is small and lightweight and has stable performance under different working conditions, good environmental adaptability, and excellent overall performance. The potential of composite electrodes for a wide range of applications in emerging wearable multifunctional electronic devices is shown by fabricating wearable strain sensors and heated films based on this electrode. This method can be used to manufacture simple, low-cost, high-performance, and highefficiency electrodes.
