The present paper analyses a surface plasmon resonance (SPR) biosensor based on graphene that leads to improvement on the efficiency of an urea biosensor due to high adsorption. Kretschmann configuration is well known as the most effectively used technique for plasmon excitation. In this work, we investigated the effect of MoS 2 with a fine layer of graphene deposited on a plasmonic material, gold (Au), into the configuration. Simulation is based on finite-difference time domain (FDTD) method for analysis. The performance of SPR biosensor can be monitored by analyzing the sensitivity and full width-at-half-maximum (FWHM) of the SPR spectrum. The measurements are observed at 670 and 785 nm for urea detection. The molarity and refractive index is varied from 1.335 to 1.342 for the sensing layer. The results showed that the percentage increase in sensitivity for the proposed biosensor Au/MoS 2 /graphene over conventional biosensor Au is 98% and 202% at 670 and 785 nm, respectively, which indicates that the proposed novel SPR biosensor is better suited for urea detection.

“…In 2017, Jamil et al reported on the MoS2/graphene-based SPR sensor for urea detection. The results showed that the sensitivity of the SPR sensor was greatly enhanced by adding the number of MoS2 and graphene layer [74]. The first graphene-based SPR sensor for galection-3 detection was reported by Primo and co-workers in 2018.…”

The emergence of unintentional poisoning and uncontrolled vector diseases have contributed to sensor technologies development, leading to the more effective detection of diseases. In this study, we present the combination of graphene-based material with surface plasmon resonance technique. Two different graphene-based material sensor chips were prepared for rapid and quantitative detection of dengue virus (DENV) and cobalt ion (Co2+) as an example of typical metal ions. As the fundamental concept of surface plasmon resonance (SPR) sensor that relies on the refractive index of the sensor chip surface, this research focused on the SPR signal when the DENV and Co2+ interact with the graphene-based material sensor chip. The results demonstrated that the proposed sensor-based graphene layer was able to detect DENV and Co2+ as low as 0.1 pM and 0.1 ppm respectively. Further details in the detection and quantification of analyte were also discussed in terms of sensitivity, affinity, and selectivity of the sensor.
