“…Advantageously, the proposed method allows transfer to be conducted at low temperature that is independent of the employed material. In our previous works, we found that Au, Al, and Ag nanostructures can be melted and oxidized below 150 °C, 30,31 which highlights the importance of performing transfer at low temperature. Consequently, we selected PMMA as a flexible substrate with a low T g and used DSC analysis to show that the T g of the PMMA film with the thickness of 150 μm (Figure 2a).…”

“…The obtained spectra featured only the typical peak of Au at the interface between Au and PMMA. Peaks due to Au oxidation were not observed, as transfer was conducted at 110 °C, that is, at a temperature higher that the T g of the PMMA film and lower than the oxidation temperature of Au (150 °C) . It was concluded that above its T g , the deformed PMMA film covers the interface of the deposited materials, which are thus physically detached from the donor polymer stamp and transferred onto the PMMA substrate (Figure S3).…”

To explain the mechanism of adhesive-free transfer, we evaluated the T g of PMMA film and the binding energy of the metal−polymer interface.…”

Herein, we develop an adhesive-free double-faced nanotransfer lithography (ADNT) technique based on the surface deformation of flexible substrates under the conditions of temperature and pressure control and thus address the challenge of realizing the mass production of large-area nanodevices in the fields of optics, metasurfaces, and holograms. During ADNT, which is conducted on a flexible polymer substrate above its glass transition temperature in the absence of adhesive materials and chemical bonding agents, nanostructures from the polymer stamp are attached to the deformed polymer substrate. Various silicon masters are employed to prove our method applicable to arbitrary nanopatterns, and diverse Ag and Au nanostructures are deposited on polymer molds to demonstrate the wide scope of useable metals. Finally, ADNT is used to (i) produce a flexible large-area hologram on the defect-free poly(methyl methacrylate) (PMMA) film and (ii) fabricate a metasurface hologram and a color filter on the front and back surfaces of the PMMA film, respectively, to realize dual functionality. Thus, it is concluded that the use of ADNT can decrease the fabrication time and cost of high-density nanodevices and facilitate their commercialization.

“…This stamping method provided the method for fabrication of various structural graphene-based hybrid arrays such as the line, grid and dot arrays, which structures were evaluated to find the optimal structure for differentiation of MSCs. In addition, using the stamping method, the metallic nanopattern array was developed through the combined use of stamping method and nano-transfer printing technique (Hwang et al, 2019 ). For achieving this goal, authors prepared the nanopattern template using the stamping method, and then, metal ions were deposited on the prepared nanopattern template.…”

The electrochemical technique is one of the most accurate, rapid, and sensitive analytical assays, which becomes promising techniques for biological assays at a single-cell scale. Nanometals have been widely used for modification of the traditional electrodes to develop highly sensitive electrochemical cell chips. The electrochemical cell chips based on the nanostructured surface have been used as label-free, simple, and non-destructive techniques for in vitro monitoring of the effects of different anticancer drugs at the cellular level. Here, we will provide the recent progress in fabrication of nanopatterned surface and cell-based nanoarray, and discuss their applications based on electrochemical techniques such as detection of cellular states and chemicals, and non-destructive monitoring of stem cell differentiation.

“…Different kinds of noble metal NW arrays (Pd, Pt, Au, and Ag; 100 nm width × 200 nm pitch × 20 nm thickness) were fabricated by depositing the corresponding metals onto the patterned polymer on the PET film by electron beam evaporation (Daeki Hi-Tech Co., Ltd., Korea) at a rate of 1 Å s –1 . Subsequently, nanowelding of the metal NW arrays was implemented using an abovementioned method at a pressure of 5 bar and a temperature of over 160 °C for 10 min by thermal nanoimprinting (Hutem Co, Korea).…”

Herein, a nanowelding technique is adopted to fabricate three-dimensional layer-by-layer Pd-containing nanocomposite structures with special properties. Nanowires fabricated from noble metals (Pd, Pt, Au, and Ag) were used to prepare Pd− Pd nanostructures and Pd−Au, Pd−Pt, Pd−Ag, and Pd−Pt−Au nanocomposite structures by controlling the welding temperature. The recrystallization behavior of the welded composite materials was observed and analyzed. In addition, their excellent mechanical and electrical properties were confirmed by performing 10,000 bending test cycles and measuring the resistances. Finally, flexible and wearable nanoheaters and gas sensors were fabricated using our proposed method. In comparison with conventional techniques, our proposed method can not only easily achieve sensors with a large surface area and flexibility but also improve their performance through the addition of catalyst metals. A gas sensor fabricated using the Pd−Au nanocomposites demonstrated 3.9-fold and 1.1-fold faster H 2 recovery and response, respectively, than a pure Pd−Pd gas sensor device. Moreover, the Pd−Ag nanocomposite exhibited a high sensitivity of 5.5% (better than that of other fabricated gas sensors) for 1.6% H 2 concentration. Therefore, we believe that the fabricated nanocomposites appear promising for wide applications in wearable gas sensors, flexible optical devices, and flexible catalytic devices.
