The goal of this research is to develop a nanosensor that integrates a zeolite/dye sensing unit with an optoelectronic detector, fully integrated into a portable gas sensor. The device will detect and measure more than one target gas at the same time. Since nanoporous structures of zeolites are manipulated, the device is expected to be more accurate, more sensitive, is able to better differentiate and detect any one target in a mixture of different gases. This is achieved by incorporating fluorescent dyes into the zeolites’ cavities, measuring gas absorption, desorption and photo-chromic interaction of dye and gases, interfacing the zeolite/dye sensor arrays with light source and electronic detectors. The electronic part of the device is fully customized VLSI chip. The final device will be packaged into a portable unit. The designed and packaged prototype will be presented.
