“…Electron beam lithography allows fabrication of features with well-defined nanogaps that is not easily achieved by any other techniques; however, the operational cost involved in creating large areas of substrates is high, while the small areas that are typically patterned using the technique offer less throughput, and the yield that is crucial for scaling up is compromised. 20,21 Nanoimprint lithography (NIL) has been used to fabricate highly periodic nanodisc, nanocone, and nanohole metal arrays for plasmon-resonant SERS structures on both hard surfaces and soft surfaces such as plastics. 14,22−24 In all cases, the geometry and structure uniformity have played a key role in their high SERS performance.…”

We demonstrate the nanofabrication of flexible plasmonic sensors comprising of gold nanocones achieved by nanoimprint lithography on polycarbonate (PC) sheets. Thermal imprinting was performed consistently over a large area (roughly the size of a 6 in. wafer) with a batch process; this can be extended to a continuous process using UV roll-toroll nanoimprinting. This provides a process to scale up the fabrication of continuous imprinted rolls of PC sheets at an optimal rate of 3−5 m/min. The geometry of the peaks and the valleys of the nanocones in the as-imprinted PC is defined by the nickel mold used during imprinting; however, the gaps between the nanocones are tailored by varying the thickness of the gold deposited onto the substrate. Two different thicknesses of gold were deposited to study the effect of geometry on plasmonic sensing. The resulting PC sheet with gold coating enables highly sensitive detection of analytes by Surface Enhanced Raman Spectroscopy (SERS) by virtue of plasmonic hotspots generated at the valleys, whose presence was confirmed by scattering scanning near-field optical microscopy. This is promising, particularly when the SERS substrate developed is highly reproducible, cost-effective, transparent, and flexible, finding application in nanoplasmonic sensing and on-field environmental monitoring, where rigid SERS substrates would not be appropriate.

“…In the practical application, silver nanoparticles are coated on the substrate, which is known as SERS substrate. Mostly, researchers start to prepare good colloidal silver nanoparticles and then to deposite them on a certain substrate using spin coating technique [8], Langmuir Blodgett technique [9], drop dry technique [2], block copolymer process [10] and printing technique [11] which are known quite complicated. Furthermore, the silver nanoparticles are sometimes not easily to deposit on the substrate, thus the silver nanoparticles disappear when the substrate is immersed in liquid sample or analyte.…”

Silver nanoparticle is useful metallic nanoparticle due to plasmonic property. One of the most important application of silver nanoparticle is enhancing Raman spectrum using so-called surface-enhanced Raman spectroscopy (SERS). Mostly, researchers synthesize colloidal silver nanoparticles and deposite on substrate to form SERS substrates. In this work, we simplified the synthesis of SERS substrate by use of microwave. We have successfully grown silver nanoparticles on unpolished silicon substrate using single step microwave-assisted technique. The unpolished silicon substrate has micro-size chambers that are useful for Raman measurement. The silver nanoparticles on silicon substrate were approximately 88 nm in diameter. Our experiment using corn syrup revealed that our SERS substrate enhance Raman peaks spectra of glucose and galactose by more than 16 times.

“…For substrates, they should suffer from the reproducibility and the limited stability which are not suitable for the large-scale production of SERS-based sensors. [20][21][22] Research illustrates complex plasmon propagation can be occurred more with the symmetry breaking, and in the gaps formed in these materials and along the structure more intense electromagnetic field generation is also occurred. Therefore, the anisotropic materials are ideal candidates for SERS.…”

Owing to the definitely excellent property of nanostructures such as controllable release of ions from the buried nanoscale thin layers, cell response to microscale morphological changes of substrates, distinctively enhancing sensitivity rendered by electrodes with sizes less than 10 micrometers, and dramatically increasing electromagnetic field from local surface plasmon resonance of nanostructures, nanostructures are playing more and more crucial role in the challenging fields. As one of the most sensitive spectroscopic tools, surface enhanced Raman scattering (SERS) shows highly sensitive biological and chemical detection, such as applications for a better biomedical applications and ecotoxicology. It is well known that surfaces with functioned nanostructures often possessthe formation of surface plasma resonance resulted in SERS distinctive enhancement attractively. Therefore, nanostructures(such as nanorods and nanobranches/wires, nanofractal, nanoprisms, and hybrid nanostructures) for SERS are marked aim to provide the related vital information. It should be pointed out that there are a lot of substantial improvements related to the technical innovation in SERS fabrication with anisotropic nanostructures. However, obstacles or challenges are still to prevent these techniques from extensively applying in the practical applications, especially for the SERS-based systems. The significantly crucial case is that it is hard to control anisotropic nanoobjects assembly into ordered structures because the degree of order among the individual building blocks, spatial arrangement and the assembly direction determine the new and/or improved properties.
