“…Wi et al proposed a continuous production method of LSPR-based sensors on a transparent flexible substrate by integrating a soft R2R NIL process and an angled evaporation process. They also measured the beta amyloid to the femtogram-level (10 −15 g) using the fabricated sensor, and verified the excellent LSPR sensor performance [179]. As a follow-up study, they used the LSPR sensor to measure the concentration of polystyrene beads by size, showing the versatility of the complex 3D plasmonic nanostructure [180].…”

Metasurfaces have shown promising potential to miniaturize existing bulk optical components thanks to their extraordinary optical properties and ultra-thin, small, and lightweight footprints. However, the absence of proper manufacturing methods has been one of the main obstacles preventing the practical application of metasurfaces and commercialization. Although a variety of fabrication techniques have been used to produce optical metasurfaces, there are still no universal scalable and high-throughput manufacturing methods that meet the criteria for large-scale metasurfaces for device/product-level applications. The fundamentals and recent progress of the large area and high-throughput manufacturing methods are discussed with practical device applications. We systematically classify various top-down scalable patterning techniques for optical metasurfaces: firstly, optical and printing methods are categorized and then their conventional and unconventional (emerging/new) techniques are discussed in detail, respectively. In the end of each section, we also introduce the recent developments of metasurfaces realized by the corresponding fabrication methods.

“…20 The technology was then implemented as R2R, for the first time by S. H. Ahn and L. J. Guo. 21 The R2R UV-NIL technology can be applied to flexible polymers (e.g., metal foil, paper, flexible glass, PS, PET, PEEK, PP and PEN §) [22][23][24][25][26] In our R2R UV-NIL process, structures are transferred from a large polymer, nickel or steel stamp, so-called "shim", to an uncured, acrylate-based photoresin, which is initially rotogravure printed onto a polymer foil (shown in Fig. 1).…”

“…Recently, Wi et al investigated a double bent Au structure on a flexible polyethylene terephthalate (PET) film and its effect on the sensitivity of LSPR properties, which enables the detection of proteins with femtogram-level sensitivity (Wi et al, 2017). In the report, the finite-difference time-domain (FDTD) simulations show that the folding of the Au structures accommodates the longer plasma oscillations in the confined structures, allowing for high sensitivity to the refractive index change of the surrounding media (Miller and Lazarides, 2005;Mayer and Hafner, 2011).…”

Localized surface plasmon resonance (LSPR) is a powerful platform for detecting biomolecules including proteins, nucleotides, and vesicles. Here, we report a colloidal gold (Au) nanoparticle-based assay that enhances the LSPR signal of nanoimprinted Au strips. The binding of the colloidal Au nanoparticle on the Au strip causes a red-shift of the LSPR extinction peak, enabling the detection of interleukin-10 (IL-10) cytokine. For LSPR sensor fabrication, we employed a roll-to-roll nanoimprinting process to create nanograting structures on polyethylene terephthalate (PET) film. By the angled deposition of Au on the PET film, we demonstrated a double-bent Au structure with a strong LSPR extinction peak at ∼760 nm. Using the Au LSPR sensor, we developed an enzyme-linked immunosorbent assay (ELISA) protocol by forming a sandwich structure of IL-10 capture antibody/IL-10/IL-10 detection antibody. To enhance the LSPR signal, we introduced colloidal Au nanocube (AuNC) to be cross-linked with IL-10 detection antibody for immunogold assay. Using IL-10 as a model protein, we successfully achieved nanomolar sensitivity. We confirmed that the shift of the extinction peak was improved by 450% due to plasmon coupling between AuNC and Au strip. We expect that the AuNC-assisted LSPR sensor platform can be utilized as a diagnostic tool by providing convenient and fast detection of the LSPR signal.
