|Design and Packaging: NEMS Portable Gas Sensing System|
|Keywords: Zeolite , Nile red, Portable sensing device|
|In this research, synthetic nanoscale zeolites-Y are being explored as a host for development of the gas sensing system. This novel material has large surface-to-volume ratio due to the porous structure. The porous structure of zeolites has been used to provide excellent absorption capability for different gases. Synthetically produced zeolites with different sized pores are capable of capturing appropriate sized gas molecules. The gas molecules which are larger in size than that of a given zeolite are rejected and only compatible gas molecules are captured in the sensing cavity. This property has been explored in this research to develop portable harmful gas detection device for commercial as well as homeland security use. Firstly, the paper will address the procedure used to coat zeolite cavity with nile red dyes. The zeolite internally coated with nile red dyes will have ability to detect different fluorescent wavelengths as result of reaction of gas molecules with nile red dyes. Secondly, the complete novel portable host-guest sensing system has been in process of design. The simulation of performance at different stages of design will be presented.|
