“…Till now, several studies have been made to improve the sensitivity and optimize the LOD of planar biosensors [143][144][145]. These planar waveguide-based biosensors are common to being highly sensitive, compact in size, label-free, and have multiplexed processing [146,147]. They also permit a simple, fixed-wavelength read-out, which makes them suitable low-cost diagnostic monitoring devices.…”

Surface plasmons, continuous and cumulative electron vibrations confined to metal-dielectric interfaces, play a pivotal role in aggregating optical fields and energies on nanostructures. This confinement exploits the intrinsic subwavelength nature of their spatial profile, significantly enhancing light–matter interactions. Metals, semiconductors, and 2D materials exhibit plasmonic resonances at diverse wavelengths, spanning from ultraviolet (UV) to far infrared, dictated by their unique properties and structures. Surface plasmons offer a platform for various light–matter interaction mechanisms, capitalizing on the orders-of-magnitude enhancement of the electromagnetic field within plasmonic structures. This enhancement has been substantiated through theoretical, computational, and experimental studies. In this comprehensive review, we delve into the plasmon-enhanced processes on metallic and metamaterial-based sensors, considering factors such as geometrical influences, resonating wavelengths, chemical properties, and computational methods. Our exploration extends to practical applications, encompassing localized surface plasmon resonance (LSPR)-based planar waveguides, polymer-based biochip sensors, and LSPR-based fiber sensors. Ultimately, we aim to provide insights and guidelines for the development of next-generation, high-performance plasmonic technological devices.

“…The final thickness of the coating will determine the location of the resonance wavelength. In particular, 8 cycles of dip-coating and annealing permitted to obtain an LMR with a resonance wavelength centred at 673 nm, which corresponded to the first Transverse Electrical (TE) polarization mode [18].…”

The fabrication and characterization of an ammonia (NH3) gas optical sensor based on Lossy Mode Resonances (LMR) is presented in this work. A chromium (III) oxide (Cr2O3) thin film deposited onto a planar waveguide was used as LMR supporting coating. The obtained LMR shown a maximum attenuation wavelength or resonance wavelength centred in 673 nm. The optical properties of the coating can be modified as a function of the presence and concentration of NH3 in the external medium. Consequently, the refractive index of the Cr2O3 thin film will change, producing a red-shift of the resonance wavelength. Obtained devices were tested for different concentrations of NH3 as well as repetitive cycles. Concentrations as low as 10 ppbv of NH3 were detected at room temperature. Machine learning regression models were used to mitigate the cross sensitivity of the device under temperature and humidity fluctuations.
