AB  - In this paper we review some metasurfaces with negative values of effective refractive index, as scaffolds for a new generation of surface plasmon polariton-based biological or chemical sensors. The electromagnetic properties of a metasurface may be tuned by its full immersion into analyte, or by the adsorption of a thin layer on it, both of which change its properties as a plasmonic guide. We consider various simple forms of plasmonic crystals suitable for this purpose. We start with the basic case of a freestanding, electromagnetically symmetrical plasmonic slab and analyze different ultrathin, multilayer structures, to finally consider some two-dimensional "wallpaper" geometries like split ring resonator arrays and fishnet structures. A part of the text is dedicated to the possibility of multifunctionalization where a metasurface structure is simultaneously utilized both for sensing and for selectivity enhancement. Finally we give an overview of surface-bound intrinsic electromagnetic noise phenomena that limits the ultimate performance of a metasurfaces sensor.

AB  - Multilayered composite systems of alternately electrodeposited nanocrystalline Cu and Ni films on cold-rolled microcrystalline copper substrates were fabricated. Highly-densified parallel interfaces which can give rise to high strength of composites are obtained by depositing layers at a very narrow spacing. The mechanical properties of the composite systems were characterized using Vickers microhardness testing with loads ranging from 1.96 N down to 0.049 N. Dependence of microhardness on layer thickness, Ni/Cu layer thickness ratio and total thickness of the film was investigated. The microhardness increased with decreasing the layer thickness down to 30 nm and it is consistent with the Hall-Petch relation. Composite hardness model of Korsunsky was applied to the experimental data in order to determine the composite film hardness. The highest value of all the composite film hardness values was obtained when the ratio of Ni: Cu layer thickness was 4:1.

AB  - We investigated intrinsic noise in plasmonic sensors caused by adsorption and desorption of gaseous analytes on the sensor surface. We analyzed a general situation when there is a larger number of different analyte species. We applied our model to calculate various analyte mixtures, including some environmental pollutants, toxic and dangerous substances. The spectral density of mean square refractive index fluctuations follows a dependence similar to that of generation-recombination noise in photodetectors, flat at lower frequencies and sharply decreasing at higher. Some of the calculated noise levels are well within the detection range of conventional surface plasmon resonance sensors. An AD noise peak is observed in temperature dependence of mean square refractive index fluctuations, thus sensor operating temperature may be optimized to obtain larger signal to noise ratio. A significant property of AD noise is its rise with the decreasing plasmon sensor area, which means that it will be even more pronounced in modern nanoplasmonic devices. Our consideration is valid both for conventional surface plasmon resonance devices and for general nanoplasmonic devices.

AB  - In this work we analyze fishnet-type optical metamaterials with full electromagnetic symmetry, fabricated in an ultrathin, freestanding film (self-supported nanomembrane). We utilized the finite element method to simulate the response of various laminar fishnet geometries, including metal-dielectric-metal and dielectric-metal-dielectric-metal-dielectric multilayers. We varied metal and dielectric thickness, nanoaperture radius, metal and dielectric materials. We considered the tunability of the spectral characteristics of the fishnet by bringing a dielectric analyte in contact with its exposed surfaces. Such tunability is of importance for all-optical sensors of chemical or biological analytes, but also for the performance of general fishnet nanoaperture arrays in real operating conditions, where the introduction of the ambient gases and fluids will modify their plasmonic properties.

Nanomembranes need to be incorporated into coherent and ambitious programs of nanotechnology research, with aggressive funding and awareness-increasing campaigns. A care should be taken at that both about the fundamental and the applied aspects of research, since the recent developments clearly indicate that the field may have many promises and even surprises in stock.

AB  - A novel, simple approach for analytical modelling of thermal flow sensors has been implemented. It is based on unification of results obtained using the already developed two-zone analytical model and theory of laminar fluid flow over uniformly heated plate. This model can be used in order to extract the main parameters for various geometrical configurations of thermal flow sensors. Presented analytical model was further verified by experimental results. Flow tests were performed using multipurpose MEMS flow sensors consisting of two thermopiles, with 30 p(+)Si/Al thermocouples each, and a "U" shaped p(+)Si heater. Thermally isolating membrane was formed of sputtered SiO(2) and residual n-Si layer. Experimental evaluation was performed under various flow conditions and applied heating power values. The results showed excellent agreement with theoretical predictions.

AB  - We investigated the influence of zero-point fluctuations (vacuum fluctuations, optical quantum noise) to the optical response of electromagnetic metamaterials containing dielectrics with third-order Kerr-like nonlinearity. We determined the zero-point noise and calculated it for different analytes, including those used in forensic analysis and organic pollutants. The zero-point noise level is highest for shortest-wavelength plasmons and decreases towards long-range plasmons. It may be tailored through a convenient design of the metamaterial structure. Since noise spectral power is proportional to the nonlinearity of the analyte species present, we considered the possibility to use zero-point noise as an auxiliary tool for identification of targeted nonlinear samples. We believe that our investigation could be of importance in homeland defence, forensics, biomedicine, etc.

abstract = "We investigated the influence of zero-point fluctuations (vacuum fluctuations, optical quantum noise) to the optical response of electromagnetic metamaterials containing dielectrics with third-order Kerr-like nonlinearity. We determined the zero-point noise and calculated it for different analytes, including those used in forensic analysis and organic pollutants. The zero-point noise level is highest for shortest-wavelength plasmons and decreases towards long-range plasmons. It may be tailored through a convenient design of the metamaterial structure. Since noise spectral power is proportional to the nonlinearity of the analyte species present, we considered the possibility to use zero-point noise as an auxiliary tool for identification of targeted nonlinear samples. We believe that our investigation could be of importance in homeland defence, forensics, biomedicine, etc.",

AB  - We analyzed the intrinsic noise of plasmonic sensors caused by the adsorption-desorption of gaseous analytes on the sensor surface. We analyzed a general situation when there is a larger number of different species in the environment. We developed our model and applied it to calculate various analyte mixtures, including some environmental pollutants, toxic and dangerous substances. The spectral density of mean square refractive index fluctuations follows a dependence similar to that of generation-recombination noise in photodetectors, flat at lower frequencies and sharply decreasing at higher. Some of the calculated noise levels are well within the detection range of conventional surface plasmon resonance sensors. One of the obvious conclusions is that AD noise may be an important limiting factor in monitoring process kinetics by nanoplasmonic sensors. An AD noise peak is observed in temperature dependence of mean square refractive index fluctuations, thus sensor operating temperature may be optimized to obtain larger signal to noise ratio. A significant property of AD noise is its increase with the plasmon sensor area decrease, which means that it will be even more pronounced in modern nanoplasmonic devices. Our consideration is valid both for conventional surface plasmon resonance devices and for general nanoplasmonic devices. This research could be of importance in diverse areas such as environmental sensing, homeland security, forensic applications, life sciences, etc.

AB  - We considered figures of merit for chemical and biological sensors based on plasmonic structures and utilizing adsorption/desorption mechanism. The operation of these devices in general is limited by noise determining the minimum detectable refractive-index change. We dedicated our work to the intrinsic noise mechanisms connected with the plasmonic process itself. In contrast, most of the available literature is almost exclusively dedicated to the external noise sources (illumination source and photodetector). Reviewing the refractive-index fluctuations caused by thermal, adsorption-desorption and 1/f noise, we observed a striking analogy between the qualitative behavior of noise in (nano) plasmonic devices and that in semiconductor infrared detectors. The power spectral densities for noise in both of these have an almost identical shape; the adsorption-desorption noise corresponds to generation-recombination processes in detectors, while the other two mechanisms exist in the both types of the devices. Thus the large and mature existing apparatus for infrared detector noise analysis may be applied to the plasmonic sensors. Based on the observed analogy, we formulated the noise-equivalent refractive-index and the specific detectivity as the figures of merit to analyze the ultimate performance of plasmon sensors. The approach is valid for conventional surface plasmon resonance sensors, but also for nanoplasmonic and metamaterial-based devices.

AB  - In this work we consider the tuning of spectral reflectance of fishnet metamaterials with circular or elliptic apertures due to the presence of dielectric analyte adsorbed within the pores of the dielectric part. We simulated the electromagnetic response of the fishnet metamaterials for the optical range utilizing the finite element method. Our investigation is dedicated to ultrathin, freestanding laminated structures (metal-dielectric-metal self-supported nanomembrane sandwiches with nanometric thickness). We also investigated some issues connected with experimental fabrication of the freestanding fishnets for adsorbtion-based sensors.
