“…The electrons start oscillation (resonance) with the same light's frequency, at this point, the lowest intensity has been recorded (dark region, no reflection), and this is the interaction between the charge of metal and electromagnetic wave. This evanescent wave is naturally fixed to a second medium (dielectric side).Lowest intensity occurs at a given angle (resonance angle), indicating that the light's energy is transferred to charge density variation, the gathering of oscillation electrons is called surface plasmon resonance (SPR) and It is referred to as evanescence depicted in figure (4). The SP wave is launched at the gold/air interface if the angle is fixed at a specific value, this coupling gives an SPW in dimensions (2D), as seen in formula (6).…”

“…The minimum intensity is known as the dark zone, also referred to the SPR angle, is the point where light energy is converted to electron resonance. The metal free electrons' interact with the activator light beam and it's vibrating resonantly with the exact same frequency of beam light shown in figure (4). This was done to obtain incident angle that may stimulate the SPR.…”

“…In most situations, gold has greater detection sensitivity in the visible region of the spectrum; hence it's usually used for the plasmonic layer, less oxidized, and has a high resistance to pollutants in the environment. The gold single film SPR sensor on prism developed by us is demonstrated here, Optimum metal lengths, angle of incidence, and dielectric layer all affect SPR sensibility [4][5][6][7][8][9][10]. It's found that at a certain angle, the configuration has a superior sensitivity than the others, the angle is known as 𝜃 𝑠𝑝𝑟 .…”

The current work includes measurements of the resonance angle and reflectance for p-polarization of the electric field by using the Fresnel equation at a given length. Gold's surface plasmon wave can be seen at the metal-to-air boundary. We try to determine the greatest (SPR) angle for a metal thin layer that is most suitable for the surface plasmon excitation while stimulated by a laser. SPR was performed of a single film of gold placed on a glass prism; there are SPR modes in this structure, which match the surface plasmon. We also suggest that the SPR mode associated with the Au surface, which is extremely sensitive to changes in the surrounding environment, particularly (dielectric). A few considerations to be taken into account to attain the SPR, like the incident angle of light rays addressed and analyzed for the purpose of finding the essential value for the plasmon to be emerge; the gold/air resonance angle. Furthermore, we can compare our result with other work, which was performed by using the Finite-Element-Method (FEM), the simulation is done by FDTD (Finite Difference Time Domain) software. SPR was applied in a variety of domains, containing biomedicine science, optics, biomedicine, photo-thermal plasmon, and health.

The work presented here describes a simple, low-cost, and unconventional technique to fabricate a 2D nanosquare array using magnetic force assisted thermal nanoimprint lithography (MF-TNIL). The nanofabrication process involves two steps: (i) fabrication of a 2D nanosquare array template on a laminated plastic sheet via sequential thermal nanoimprinting of linear nanograting polydimethylsiloxane (PDMS) stamp, and (ii) reversal imprinting of template on UV curable polymer using soft UVnanoimprint lithography. Without using an expensive nanofabrication tool, our proposed technique can fabricate nanosquare array over an area of 1×1 cm 2 with individual nanosquare having a feature size of about 383 nm×354 nm×70 nm. We believe that our proposed MF-TNIL represents a promising nanofabrication technique that will allow fabricating various types of nanostructures for their applications in developing sensors, anti-reflective surfaces, self-cleaning surfaces, etc. OPEN ACCESS RECEIVED

“…The grating-coupled SPR sensors were used as temperature sensors [ 21 ], RI sensors [ 24 , 25 , 33 , 35 ] and as biosensors [ 10 , 18 , 19 , 32 , 36 , 37 , 38 , 39 , 40 ]. Gold-coated polymer gratings brought an efficient way for fabrication of SPR gratings instead of using thick metal layers [ 29 , 30 , 35 , 41 , 42 , 43 ]. Although many of the presented SPR structures are large-scale, the reduction in their dimensions is needed for microfluidic and lab-on-a-chip (LOC) devices.…”

IP-Dip-Based SPR Structure for Refractive Index Sensing of Liquid Analytes

et al. 2021

View full text Add to dashboard Cite

In this paper, we present a two-dimensional surface plasmon resonance structure for refractive index sensing of liquid analytes. The polymer structure was designed with a period of 500 nm and prepared in a novel IP-Dip polymer by direct laser writing lithography based on a mechanism of two-photon absorption. The sample with a set of prepared IP-Dip structures was coated by 40 nm thin gold layer. The sample was encapsulated into a prototyped chip with inlet and outlet. The sensing properties were investigated by angular measurement using the prepared solutions of isopropyl alcohol in deionized water of different concentrations. Sensitivity of 478–617 nm per refractive index unit was achieved in angular arrangement at external angle of incidence of 20°.
