Biosensors are enormously used for diagnosing applications owing to its compact size and simplicity. Biosensors task is to identify presence of targeted molecule and provide result into a measurable signal. Cantilever is one of the most reliable methods of designing biosensor. Cantilever biosensor is preferable because analyte required is very less as compared to conventional method. In order to detect presence of specific bio-molecule, it is necessary to immobilized particular receptors for that bio-molecule. If sample contain bio-molecule of the interest then cantilever show deflection otherwise it will remain in its original position. Same deflection can be obtain by applying force(equivalent to bio-agent mass) to cantilever .This paper relates acting mass of bio-particle with external applied force in order to get same deformation of cantilever. Coventorware software is used for simulation. For simulation results shows mechanical properties of device after application of load.
