Simulation of Cantilever Biosensor for Detection of Tuberculosis

Abstract: Worldwide Mycobacterium Tuberculosis comes under top ten diseases, which affect to millions of people every year. Due to its complicated structure, it is very difficult job to diagnose this infectious disease in time. In this research article, first the complications of tuberculosis and some detection techniques are studied. After that, for fast and within time detection of tuberculosis, Cantilever Biosensor with various shapes are simulated. The Cantilever is design with Poly-Silicon material and its surface coated with ESAT-6 antigen antibody. For stress generation a load forces are apply from 10N to 100N and displacement of all the models are analyze. After analysis it has been recorded that Rectangular shape generates maximum displacement as compare with other shapes. Rectangular shape cantilever biosensor achieved 1.71 x 1028 µm displacement with 100N load force.
