This chapter discusses the unique and novel properties of 2D materials useful for toxic gas and biosensing applications. The work presented in this chapter mainly focuses on latest research done on 2D materials related to toxic gas and biosensing for surface plasmon resonance based sensors. Here, we proposed a surface plasmon resonance sensor utilizing P3OT thin films which can sense different concentration of NO2 gas. The performance of proposed design is evaluated by calculating sensitivity, detection accuracy and quality factor, with and without use of silicon layer. Sensitivity of proposed sensor increases by using silicon.

The tropospheric aerosol characterization is important for understanding environmental process as well as human health safety. In this study, the surface plasmon resonance sensor is proposed for the detection of ammonium sulfate which is an important component of aerosols. The reflectivity of proposed sensor waveguides is calculated as a function of the incident angle using the transfer matrix method. The performance of proposed sensors having sol-gel film of tetraethylorthosilane and thymolblue are studied and compared. Firstly, the dispersion characteristics are obtained for different modes, and it is observed that the modes are tightly bound in thymol blue waveguide in comparison to tetraethylorthosilane waveguide. Further, the magnetic field distributions are also studied and compared for proposed waveguide sensor configurations. It is found that the sol-gel film of thymol blue waveguide provides high sensitivity while tetraethylorthosilane waveguide shows high figure of merit. Keywords: aerosol, surface plasmon resonance sensor; reflectivity, sensitivity, detection accuracy.
