The fabrication of large-area and flexible nanostructures currently presents various challenges related to the special requirements for 3D multilayer nanostructures, ultrasmall nanogaps, and size-controlled nanomeshes. To overcome these rigorous challenges, a simple method for fabricating wafer-scale, ultrasmall nanogaps on a flexible substrate using a temperature above the glass transition temperature (Tg) of the substrate and by layer-by-layer nanoimprinting is proposed here. The size of the nanogaps can be easily controlled by adjusting the pressure, heating time, and heating temperature. In addition, 3D multilayer nanostructures and nanocomposites with 2, 3, 5, 7, and 20 layers were fabricated using this method. The fabricated nanogaps with sizes ranging from approximately 1 to 40 nm were observed via high-resolution transmission electron microscopy (HRTEM). The multilayered nanostructures were evaluated using focused ion beam (FIB) technology. Compared with conventional methods, our method could not only easily control the size of the nanogaps on the flexible large-area substrate but could also achieve fast, simple, and cost-effective fabrication of 3D multilayer nanostructures and nanocomposites without any post-treatment. Moreover, a transparent electrode and nanoheater were fabricated and evaluated. Finally, surface-enhanced Raman scattering substrates with different nanogaps were evaluated using rhodamine 6G. In conclusion, it is believed that the proposed method can solve the problems related to the high requirements of nanofabrication and can be applied in the detection of small molecules and for manufacturing flexible electronics and soft actuators.

“…For instance, Lee et al used thermal sintering at 200 °C for 20 min to reduce resistance in a printed AgNW trace from 1000 to 100 Ω/sq [ 118 ] and Li et al photonically welded NWs to reduce sheet resistances from 53 to 7.1 Ω/sq [ 23 ]. An example SEM image of laser-welded AgNWs is provided in Figure 7 c [ 119 ]. Finally, NWs can be welded by NPs embedded in a matrix film.…”

Recent Advances in High-Throughput Nanomaterial Manufacturing for Hybrid Flexible Bioelectronics

Hybrid flexible bioelectronic systems refer to integrated soft biosensing platforms with tremendous clinical impact. In this new paradigm, electrical systems can stretch and deform with the skin while previously hidden physiological signals can be continuously recorded. However, hybrid flexible bioelectronics will not receive wide clinical adoption until these systems can be manufactured at industrial scales cost-effectively. Therefore, new manufacturing approaches must be discovered and studied under the same innovative spirit that led to the adoption of novel materials and soft structures. Recent works have taken mature manufacturing approaches from the graphics industry, such as gravure, flexography, screen, and inkjet printing, and applied them to fully printed bioelectronics. These applications require the cohesive study of many disparate parts. For instance, nanomaterials with optimal properties for each specific application must be dispersed in printable inks with rheology suited to each printing method. This review summarizes recent advances in printing technologies, key nanomaterials, and applications of the manufactured hybrid bioelectronics. We also discuss the existing challenges of the available nanomanufacturing methods and the areas that need immediate technological improvements.

“…(Reske et al, 2014) Typical structures are NPs with average size 20-100 nm, nanorods with 200-300 nm length, ~150 nm width and ~20-40 nm thickness, nanowires with an average diameter of 150 nm and length of 53 μm or nanospheres, being single crystals of an average size of 23.4±1.5 nm. (Sahai et al, 2016;Zuo et al, 2017;Dang et al, 2017;Tran et al, 2017;Guo et al, 2014) CuNPs have valuable physical properties-good electrical and thermal conductivity, light absorption with an absorption peak at 570-580 nm. They are more reactive compared to other metallic NPs.…”

Copper is an important metal in analytical and industrial fields as it has excellent thermal and electrical properties. In many disciplines, like electronics, optics, and others, copper nanoforms pay more attention than other noble metals nanoparticles. Attractive are its natural abundance, low costs and high activity toward many analytes with simultaneous physical stability. Extensive use has brought new types of sensors and practical implementations. The objective of this paper is to present crucial developments of copper material in the sensing field. Practical applications in the environmental section, like chemical oxygen demand measurement or carbon dioxide reduction reaction for atmospheric CO2 reduction; technological sensors like organic light-emitting devices, electronic tongue for alcohol type determination, human skin touch and move sensor; and medical sensors for glucose, alcohol, dopamine or paracetamol detection were presented.
