Microcantilever is a crucial tool for determining and measuring sample in various fields such as chemical, physics or biology. Based on the response of the cantilever, such as the deflection or resonance frequency, that one could use to determine tension, temperature or mass. In this work, we theoretically investigate the frequency shift due to two mass attached on the surface of the cantilever. The position of the mass effects on the resonance. Moreover, we show that the correlation between two absorbed objects, such as the position and the attached time, contributes to the characteristic of the dynamics. The results can provide fruitful information for measuring in bio-sensing.
