“…As it was previously demonstrated our 2D plasmonic sample is characterized by its simple fabrication, feasible price, good efficiency and the possibility to be easily reproduced at high scales. Also, it was used by others in different domains of plasmonics, such as random lasing and biomedical substrate [18][19]. In this paper, by combining the plasmonic properties of 2D plasmonic structures with NiFe magnetic surrounding, we were able to obtain the active control over the SLR and thus thus the switching effect of a 2D magneto-plasmonic grating.…”

“…If α is the polarizability of the single particle (α=Re (α) +Im (α)) and S is the array factor, the resonance wavelength of the SLR locates at the crossing of Re(1/α) and Re (S) that is a function of the distance between the particles. 37,38 The contrast between the Im (1/α) and Im (S) plays a role in the robustness and the width of SLR. In this structure, the interference between two modes occurs at various wavelengths proportional to the lattice constant.…”

Introduction: Plasmonic biosensors provide high sensitivity in detecting the low amount of biomarkers and pharmaceutical drugs. We studied the mesenchyme cell activity under the treatment of common sedative drugs of methadone and tramadol using the integrated plasmonic-ellipsometry technique. Methods: Mesenchymal stem cells were cultured on patterned plasmonic chips under the treatment of methadone and tramadol drugs. Three cultured chips were kept non-treated as the control ones. The plasmonic-ellipsometry technique was applied to study the signaling characteristic of the cells affected by these two drugs. In this technique, optical information regarding the amplitude ratio and phase change between p- and s-polarized light was recorded. Results: This drug treatment could affect the spectral plasmonic resonance and subsequently the phase shift (Δ) and the amplitude ratio (Ψ) values under p- and s-polarized impinging light. A more significant Δ value for tramadol treatment meant that the phase split was larger between p- and s-polarized light. Tramadol also had more prominent absolute Δeff and Ψeff values in comparison with methadone. Conclusion: We showed that tramadol caused more contrast in phase shift (Δ) and amplitude ratio (Ψ) between p- and s-polarized impinging light for cultured stem cells in comparison with methadone. It means that tramadol differentiated more the optical responses for p- and s-polarized lights compared to methadone. Our proposed technique possesses the potential of quantitative and qualitative analysis of drugs on humans even on a cell scale.

Silver nanowires are the favorable material in many applications based on their plasmonic double resonance in the visible region. In this paper, thin films of Poly-vinylpyrrolidone (PVP) doped with Silver nanowires (Ag NWs) in different concentrations have been prepared. The plasmonic imaging system using a high numerical aperture objective lens excite the Surface Plasmon in these structures. The hot spot results from reflected light intensity of surface plasmon resonance (SPR) proved that increasing of concentration of Silver nanowires yields to get better hot spot in plasmonic imaging systems by choosing the appropriate wavelength.These obtained results accompanying with third order nonlinear investigations show the ability of samples usage in thermoplasmonic applications.
