Surface Plasmon Resonance (SPR) techniques are highly accurate in detecting biomolecular like blood group measurement, food adulteration, milk adulteration and recently developing as a rapid detection for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus. In order to validate the clinical diagnosis, Real-time reverse transcriptase-polymerase chain reaction (RT-PCR) of nasopharyngeal swabs has been utilized, which is time consuming and expensive. For fast and accurate detection of the SARS-CoV-2 virus, SPR based biosensing chips are described in this review article. SPR sensors have the potential to be employed for fast, accurate, and portable SARS-CoV-2 virus diagnosis. To combat the SARS-CoV-2 pandemic, there is considerable interest in creating innovative biosensors that are quick, reliable, and sensitive for COVID-19 diagnosis.

“…Besides sensitivity, Q value and FOM are also very important parameters for evaluating the performance of a sensor. Q depends on the energy loss of the biosensor in water, and the FOM is defined as the mass sensitivity multiplied by the quality factor, which directly indicates the performance of the device [ 36 ]. The Q value and FOM of the biosensor can be calculated using the following equation:

The development of MEMS acoustic resonators meets the increasing demand for in situ detection with a higher performance and smaller size. In this paper, a lithium niobate film-based S1 mode Lamb wave resonator (HF-LWR) for high-sensitivity gravimetric biosensing is proposed. The fabricated resonators, based on a 400-nm X-cut lithium niobate film, showed a resonance frequency over 8 GHz. Moreover, a PMMA layer was used as the mass-sensing layer, to study the performance of the biosensors based on HF-LWRs. Through optimizing the thickness of the lithium niobate film and the electrode configuration, the mass sensitivity of the biosensor could reach up to 74,000 Hz/(ng/cm2), and the maximum value of figure of merit (FOM) was 5.52 × 107, which shows great potential for pushing the performance boundaries of gravimetric-sensitive acoustic biosensors.

“…Furthermore, because of its low refractive index than other glass prisms, it gives greater sensitivity. The BK7 prism demonstrates the most significant SPR viewpoint while retaining a respectable minimum reflectance [40]. The design parameters used in our proposed structure have been summarized in Table 2.…”

In this proposed work, an SPR-based biosensor with dual nanofilms of a gold metal, 2-Dimensional MXene, and graphene has been proposed to detect different malaria stages. The principal obeyed by the sensor design is attenuated total reflection (ATR) with a modified Kretschmann-based configuration. Numerical computational results give the higher sensitivity for our proposed design as 227.9 degree/RIU (for single MXene and dual graphene layers at RI variation of 1.33 to 1.38 with a change of 0.01) and 258.28 degree/RIU(for trophozoite stage of malaria disease), with other performance parameters like DA computed as equal to 0.14 degree-1 , QF as 31 RIU-1 and 35.5 RIU-1, FWHM as 7.35 degree and 7.27 degree for single MXene, dual graphene nanofilms and trophozoite stage respectively. The suggested biosensor can diagnose the various stages of severe malaria disease by measuring the refractive index alteration in red blood cells (RBCs).
