“…As a new type of electrooptical material, holographic polymer-dispersed liquid crystal (H-PDLC) has many potential applications in optical communications, flat panel displays, information storage, and integrated optics [7][8][9][10][11][12][13]. A number of practical and effective instruments have been fabricated based on the unique characteristics of H-PDLCs such as optical attenuator, holographic zoom lens, and holographic volume gratings [14][15][16][17][18][19][20]. Two coherent recording beams create a sinusoidal interference optical pattern, which leads to periodic phase separation between prepolymer monomers and liquid crystal (LC).…”

We report localized surface plasmon resonance (LSPR) of silver nanoparticles (NPs) embedded in interface of phase separation of holographic polymer-dispersed liquid crystal (H-PDLC) gratings using Finite-Difference Time Domain method. We show that silver NPs exhibit double resonance peak at the interface, and these peaks are influenced by the angle of incident light. We observe a blue shift of the wavelength of resonance peak as the incident angle increases. However, the location of silver NPs at the interface has nearly no effect on the wavelength of resonance peak. Also we show near-field and far-field properties surrounding silver NPs and find that field distribution can be controlled through rotation of incident angle. Therefore, LSPR properties of silver NPs within H-PDLC gratings can be excited by appropriate wavelength and angle of the incident light.

“…However, by using polymer-dispersed liquid crystal technology based on 50 μm-thick PDLC layer formed between a transparent electrode and a ZnS:Cu phosphor layer, Song et al, have improved the luminescence efficiency by more than 15%. [36]. Xie group has used layer-bylayer (LBL) technology to develop a gold nanoparticle and toluidine blue-graphene based label-free electrochemical aptasensor for highly sensitive thrombin detection with appreciably high signal/noise ratio [37].…”

One of the biggest issues in today's healthcare industry is to find a very fast yet effective diagnostic platform, which is suitable for our busy lifestyle without compromising the detection efficiency. The major requirements of an efficient diagnostic platform can be summarized as minimum sample requirement, least reagent requirement, having options of multiple tests in a single platform, high through put analysis and last but never the least a non-expensive sample run. The largest contributor of the bio-assay industry is protein based chromogenic bio-assays, which depends on strong antigen-antibody interaction and high emissive properties of reporter dye molecule attached to the antigen. In reality, this apparently simple looking reaction system has to face several difficulties before an appreciable signal is received by the photo-detector to give an analysable dataset. With the rapid emergence of nanotechnology during last few decades, some of the critical problems have been solved [1][2][3][4][5]. However, a large number of unresolved issues still remain there. This editorial will briefly address some of those critical issues and how they have been tackled by nanotechnology. The two-most tunable variables of a bio-assay platform are the reporter molecules and the sensing platform as described by the Figure 1. We will describe both the issues separately in the next sections. Optical efficiency of the reporter moleculeThe optical efficiency of a reporter molecule suffers from two major issues, firstly the biological auto-fluorescence and secondly the fluorescence quenching of the reporter dye by the aqueous environment. The biological autofluorescence originates from the

“…In consequence, there have been many investigations of the formation mechanism and of the consequent scattering characteristics [10,11]. Furthermore, there are also many applications of PDLC films in different fields that use its scattering characteristics [6,7]. However, related applications in the field of imaging systems are worthy of further research, especially for turbulence imaging simulation.…”

In this study, the scattering properties of polymer dispersed liquid crystals (PDLC) and its optical features for use in turbulence image simulation are presented. A PDLC cell composed of a liquid crystal/monomer mixture with two indium tin oxide glass substrates, 55 wt.% E7 and 45 wt.% NOA65, is proposed. And this mixture had a thickness of 10 µm. With respect to its scattering properties, it was hypothesized that the proposed PDLC cell could be utilized as an electrically tunable turbulence imaging simulator. The measured results, two dimensional images of the transmission light, under voltages from 0 Vrms to 10 Vrms showed that the PDLC film could effectively simulate turbulence situation of a point light source under atmosphere turbulence condition to a certain extent. This PDLC film had a great potential for application in turbulence imaging simulation.
