Design and Exploration of Micro Cantilever Biosensor for Detection of Tuberculosis

According to the WHO, health is a circumstances of personal resources. There is a necessity to prevent health related issues by diagnosing the disease within time. Number of hazardous diseases are there which are not able to catch within time. Globally from top ten diseases, one of the leading cause of death is tuberculosis. Due to the complicated structure, diagnose the bacteria of tuberculosis is very tedious job. Its an airborne disease. So there is a huge requirement to build a technique which can detect tuberculosis easily and at an early stage. The purpose of the paper is to study, design, and simulate the cantilever biosensor for quick detection of tuberculosis. Micro cantilever biosensor are designed with different dimensions and shapes. The surface of micro cantilever biosensor are prepared with various materials and are coated with antibodies. The sample of patient is placed on to the cantilever, if sample is infected with tuberculosis then antibodies get binds with antigens and it generate stress on the surface and it delivers displacement. Displacement of various designs of micro cantilever were analyzed and maximum displacement were recorded. Rectangle shape with gold material of micro cantilever biosensor achieved maximum displacement as 1.71 x 10 28 µm for a load of 100N.
