Tantalum disulfide (TaS2) Based Novel Surface Plasmon Resonance Sensor with Enhanced Sensitivity using Aluminium Arsenide(AlAs)and Thallium Bromide(TlBr)

In this paper, a new SPR biosensor design is proposed that employs tantalum disulfide (TaS
2
) and offers increased sensitivity. The performance of the sensor is improved by incorporating Aluminum Arsenide (AlAs) and Thallium Bromide (TlBr) layers in its design. The proposed sensor design makes use of the exceptional features of TaS
2
, which display a remarkable sensitivity towards variations in refractive index and demonstrate excellent stability. By incorporating AlAs and TlBr layers into the sensor structure, the proposed SPR biosensor demonstrated a substantial improvement in sensitivity, making it capable of detecting low-concentration analytes with high accuracy. The effectiveness of the sensor is assessed by testing it with various analytes, and the outcomes show that the suggested sensor displays outstanding sensitivity, stability, and specificity. The proposed sensor has promising applications in various fields, including biomedical sensing, environmental monitoring, and food safety.
