|Design and Simulation of a Portable Yeast-Based Biosensor|
|Keywords: Yeast-based sensor, Yeast-based sensor, portable detection device|
|Yeast-based sensor will detect harmful substances in water. Device has been tested for detection of heavy metal ions such as As3+, Fe2+, Pb2+, and Cd2+. Presently existing systems are bulky and available in laboratories. Samples need to be sent to laboratories for evaluation and detection for harmful substances. Advantage of this device is that it is portable so that it can be used in any building or even in the field. The main reason for development of this portable device is that it would give immediate readout of harmful substances in water supply. The yeast-based sensor is packaged in such a way that it could be easily placed in the portable system. After each test, cartridge consisting of yeast cells can be easily replaced with a new one. This device is specifically targeting the problems that could occur as result of industrial harmful substances reaching water supply. The yeast-based biosensor is chosen because it has low maintenance requirements and archives high accuracy. Preliminary testing shows that the accuracy of detecting of harmful chemicals in water is as low as 2.5 ppm. This paper will present preliminary result obtained in the laboratory. Extensive simulation of complete system will be discussed in this presentation.|
