Summary: miRNAs are important biomarkers for the development and progression of various cancers. Detecting miRNAs is crucial for early-stage diagnostics and prognostics of multiple diseases. This study proposes a MXene-enhanced plasmonic biosensor for real-time and label-free detection of miRNA, with ultrasensitive detection limit and the ability to distinguish single-base mismatched miRNA. The biosensor can detect miRNA in complex media without the need for extra labels or amplification tags, holding great potential in biological applications and clinical diagnostics.

Summary: The optical dispersion properties of the 20Li2O-xBi2O3-(78-x)TeO2-1Er2O3-1Ag glass system were studied. The Eo and Ed values decrease with increasing Bi2O3 concentration, reaching a maximum at x = 11 mol%. Bi2O3 acts as a glass former, inducing bond formation and contributing to average bond strength. It also minimally transforms the glass network, leading to a maximum in Ed. The dielectric properties of the glass samples were computed. The er and ei values initially decrease at x <= 7 mol% before reaching a maximum at x = 11 mol%. The localized surface plasmon resonance of the Ag NP is dependent on the dielectric properties of Er3+ host glass. The electrical chi and Clausius-Mossotti polarizability aL show a maximum at x = 13 mol%, contributing to strong localized surface plasmon resonance.

Summary: This article presents an ultrasensitive fiber surface plasmon resonance (SPR) magnetic field sensor using an Au/TiO2 Schottky junction coated on a plastic-clad multimode fiber (PMF) and immersed in the magnetic fluid (MF). The sensor achieved a maximum magnetic sensitivity of -2.791 nm/Oe in the 5-35 Oe range, higher than most MF-based fiber magnetic field sensors. The proposed sensor can measure magnetic field strength variations with high sensitivity and accuracy, making it suitable for practical applications in various scenarios.

Summary: This study proposes an approach to enhance 2D MoS2 photosensing by combining plasmonic nanostructures and physical suspension, resulting in a hybrid structure with high responsivity and large active area. The gateless responsivity of the hybrid structure reaches 402.4 A/W at a wavelength of 532 nm, representing the highest value reported for gateless plasmonic MoS2 photodetectors. The exceptional detectivity of 2.34 x 10(12) Jones highlights the potential of this approach for designing high-performance 2D TMDC-based optoelectronic devices.
