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 © 2013 IEEE.

A novel, portable electrochemical sensing gadget has been developed to analyze the level of uric acid in human urine. It uses gold nanoparticles embedded, chemically modified carbon paste electrode. The uric acid level is identified as the main marker in a majority of the diseases, such as urolithiasis, gout, myeloma, and so on. The main objective of the present effort was to study the level of uric acid accurately in minimum time. For this, we developed an instant, real-time monitoring kit to give accurate and fast data on the level of uric acid in a real sample. The initial work focused on developing chemically modified gold nanoparticles embedded carbon paste electrode, while the later part was aimed at converting the effort into a full detecting kit with a real time display unit to display levels of uric acid and to give a suitable indication. Since the detection kit requires neither sophisticated lab nor specific conditions to work, it is portable. This can be used as a uric acid screening device even in rural health centers. This paper can help the medical practitioners as well as the lab technicians to analyze samples quickly and give better support to the patients. © 2016 IEEE.
