Answer #1

a.) BIOSENSOR cantilever is used to identify the microbased desease like prostate cancer like that to detect and identify its antigen. It consists of mainly 3 parts by which it works on. First is the bio sensor which detect the biological changes and identify it. Second is the transducer which converts the biological changes and movement into electrical signal with increased amplitude and third is the detector on which all signal transferred and detect and identify desease to compare with its given signal amplitude. It detects very small deflection approx nano scale and increase its detectability.
