“…Beyond multiplexed array detection, SPRi has been applied toward the study of bacterial films, adhesion, and mobility using the visualization capabilities offered by the technique. 45−47 Advances in SPRi instrumentation have ranged from the conservative, yet undoubtedly important end, with integrated temperature control and monitoring demonstrated, 48,49 to the more radical, including variations on traditionally used monochromatic light sources and CCD cameras. Researchers desiring both the high dynamic ranges of spectroscopic SPR and the throughput capabilities of SPRi have sought after technical solutions that allow for both, with their studies converging on wavelength interrogation for collected array images.…”

“…The utilization of SPR in gas detection has garnered significant attention due to its label-free and real-time characteristics [9,10]. However, most SPR sensors rely on measuring the intensity change in the reflected beam, which is susceptible to environmental influences and exhibits a low sensitivity to changes in the refractive index of small molecules [11,12].…”

A differential evolution particle swarm optimization (DEPSO) is presented for the design of a high-phase-sensitivity surface plasmon resonance (SPR) gas sensor. The gas sensor is based on a bilayer metal film with a hybrid structure of blue phosphorene (BlueP)/transition metal dichalcogenides (TMDCs) and MXene. Initially, a Ag-BlueP/TMDCs-Ag-MXene heterostructure is designed, and its performance is compared with that of the conventional layer-by-layer method and particle swarm optimization (PSO). The results indicate that optimizing the thickness of the layers in the gas sensor promotes phase sensitivity. Specifically, the phase sensitivity of the DEPSO is significantly higher than that of the PSO and the conventional method, while maintaining a lower reflectivity. The maximum phase sensitivity achieved is 1.866 × 106 deg/RIU with three layers of BlueP/WS2 and a monolayer of MXene. The distribution of the electric field is also illustrated, demonstrating that the optimized configuration allows for better detection of various gases. Due to its highly sensitive characteristics, the proposed design method based on the DEPSO can be applied to SPR gas sensors for environmental monitoring.

“…The biosensors can be distinguished two main types by methods of signal generation such as bioaffinity sensors and biocatalytic biosensors. The bioaffinity sensors are defined that the biological device bound with test object to occur bioaffinitive binding result in the change of the biomolecular shape or change of physical quantities such as charge, thickness, mass, heat, or optics [1]. The biocatalytic biosensors are defined that immobilized molecules react with the test object to generate biochemical metabolites [2].…”

In this paper, the L-ascorbic acid (L-AA) biosensor based on magnetic beads-ascorbate oxidase/graphene oxide/indium gallium zinc oxide/aluminum (MBs-AOX/GO/IGZO/Al) membrane was integrated with the potentiometric measurement system with the microfluidic framework in order to investigate the different sensing characteristics under the static condition and the dynamic condition. The L-AA biosensor showed the average sensitivity of 78.9 mV/decade (25 • C) under the static condition, and it showed the average sensitivity of 81.7 mV/decade (25 • C) at the optimal flow rate (25 µL/min). Besides, the XBee module was used to apply in the remote detection for the L-AA biosensor, and the experimental results were shown the average sensitivity of 78.7 mV/decade (25 • C). Moreover, we also investigated various experiments, such as temperature effect, hysteresis effect, and lifetime. These experimental results would be beneficial to the development of the L-AA biosensor based on electrochemical detection. INDEX TERMS L-ascorbic acid (L-AA), graphene oxide (GO), magnetic beads (MBs), microfluidic framework, wireless sensing system.
