The dielectric properties of complex plasma containing either metal or dielectric spherical inclusions (macroparticles, dust) are investigated. We focus on surface plasmon resonances on the macroparticle surfaces and their effect on electromagnetic wave propagation. It is demonstrated that the presence of surface plasmon oscillations can significantly modify plasma electromagnetic properties by resonances and cutoffs in the effective permittivity. This leads to related branches of electromagnetic waves and to the wave band gaps. The conditions necessary to observe the band-gap structure in laboratory dusty plasma and/or space (cosmic) dusty plasmas are discussed.

Background: Interleukin (IL)-38 is an IL-1 family cytokine that was proposed to exert anti-inflammatory effects. However, its mechanisms of action are not well understood and the identity of the IL-38 receptor(s) remains debated. Proposed candidates include the IL-1 receptor (IL-1R1), the IL-36 receptor (IL-36R) and the orphan receptor IL-1RAPL1.

The g-C3N4/CS biosensor was designed, fabricated, and tested using compounds such as glucose, urine, lactose, and flutamide at a molarity of 10 µM, which could demonstrate a high sensitivity of 200 μm-1 for flutamide. Powerful effective medium theory and FDTD simulation were used to predict the most favorable mode and plasmonic properties of a graphite carbon nitride and chitosan nanocomposite. The research also explores the characteristics of surface plasmon resonance exhibited by the nanocomposite as the chitosan content is adjusted.

Surface plasmons offer a promising avenue in the pursuit of swift and localized manipulation of magnetism for advanced magnetic storage and information processing technology. However, observing and understanding spatiotemporal interactions between surface plasmons and spins remains challenging, hindering optimal optical control of magnetism. Here, we demonstrate the spatiotemporal observation of patterned ultrafast demagnetization dynamics in permalloy mediated by propagating surface plasmon polaritons with sub-picosecond time- and sub-μm spatial- scales by employing Lorentz ultrafast electron microscopy combined with excitation through transient optical gratings.

Improving the sensitivity of biosensor has always the major challenge to measure lower detection concentration of biological samples. In this paper, a novel optical fiber surface plasmon resonance (SPR) biosensor based on TiC MXene/GNRs synergistically highly enhanced sensitivity was proposed. The TiC MXene and GNRs were coated on the optical fiber sensing probe by the electrostatic layer-by-layer (ELBL) assembly method.
