Abstract :
An electronic Nano bio-sensor is developed to detect the presence of typhoid in the earlier stage with high accuracy. The sensor is developed on a silicon substrate and Multi Walled Carbon Nano tube is aligned over it and coated with polyaniline. The antibody anti-typhi was immobilized on to the electrode to have a sensitive detection of the salmonella antigens from the samples. The resultant variation of resistance by the sensor indicates the detection of Salmonella Typhi in earlier stage and shows the accuracy of the sensor developed
