Abstract

We demonstrate the design and calibration of a novel individual carbon nanotube (CNT) based mechanical force sensor for measuring cell wall compliance. The device fabrication and in-situ mechanical characterization was carried out using a micro-manipulator inside a scanning electron microscope. This simple device acts as a micro-cantilever beam and consists of a tungsten probe with a CNT attached to its tip while the other end of CNT supports a polystyrene microsphere. We have calculated the bending modulus of individual multiwalled carbon nanotubes from the calibration tests. These values are in agreement with values available in the literature.
