Abstract: Sensors continue to make significant impact in everyday life. There has been a strong demand for producing highly selective, sensitive, responsive, and cost effective sensors. As a result, research emphasis is on developing new sensing materials and technologies. Carbon nanotubes (CNTs) have many distinct properties that may be exploited to develop next generation of sensors. The present work reviews and explores the distinct physical and mechanical properties of CNTs and CNT based mass sensors. The main thrust of this work is to highlight the present and future research and development work in the area of carbon nanotube based mass sensors for real-world applications. During recent years carbon nanotubes are being increasingly used for mass sensing. This study investigates single walled carbon nanotubes as the sensing devices for different mass and biological objects. Different aspects like wall thickness, length of CNT, diameter of CNT, different boundary conditions etc have been considered for the analysis. An expression has been formulated to detect the mass of biological objects from the shift of frequency. Continuum and Molecular structural mechanics approach has been used for investigating the dynamic responses of single walled carbon nanotube based nano resonator. Pinhole defects in SWCNT have also been investigated .Modeling of Multiwalled carbon nanotube has been carried out and the application of DWCNT as virus sensors has been investigated. FEM results also compared with the analytical results. I
