Abstract
Using carbon nanotubes for sensing the mass in a biosensor is recently proven as an emerging technology in healthcare industry. This study investigates relative frequency shifts and sensitivity studies of various biological objects such as insulin hormone, immunoglobulin G (IgG), the most abundant type of antibody, and low‐density lipoproteins (LDL) masses using the single‐wall carbon nanotubes as a biomass sensor via continuum mechanics. Uniform distributed mass is applied to the single‐wall carbon nanotube mass sensor. In this study, fixed‐free and fixed‐fixed type single‐wall carbon nanotubes with various lengths of relative frequency shifts are studied. Additionally, the sensitivity analysis of fixed‐free and fixed‐fixed type CNT biological mass sensors is carried out. Moreover, mode shapes studies are performed. The sensitivity results show better, if the length of the single‐wall carbon nanotube is reduced.

Summary
After discovering carbon nanotubes (CNT’s) [1, 2], its utilization is found to be in diverse range of applications, such as nanomechanical resonators and nanobiological sensors. e unique great physical properties of the carbon nanotube lead to various usage in different fields such as nanoelectromechanical systems and actuators. [3,4,5,6]. e use of CNT in medical fields is enormous. Many articles show the modeling techniques of elastic continuum mechanics concepts for analyzing the vibration of carbon nanotubes. Advances in Materials Science and Engineering material properties and continuum models of carbon nanotubes have been studied [11]. We developed a computationally efficient single-wall carbon nanotube as a biological mass sensor with the continuum mechanics method using the finite element method. In this study, fixed-free and fixed-fixed type single-wall carbon nanotubes with various lengths of relative frequency shifts and sensitivity analysis are examined. The sensitivity analysis of fixedfree and fixed-fixed type CNT biological mass sensors is carried out
