Effective dispersion and selective positioning of carbon nanotubes is necessary for future integration with conventional microelectronics as well as the development of novel functional devices. Limited progress has been reported in the dispersion and controlled placement of carbon nanotubes. In the present study, we dispersed carbon nanotubes using an optical tweezer cum microdissector system and then binded them onto a silicon surface. –OH groups were created on the silicon surface. Carbon nanotubes were processed to form a carboxylic group at their ends. Fourier transform infrared (FTIR) spectra were recorded to confirm the functionalization. These carbon nanotubes were made to react with silicon surface. The silicon surface was investigated under scanning electron microscope (SEM). The image showed the presence of a number of carbon nanotubes binded to the silicon surface. This kind of binding onto substrates will open up the path to applications like chemical sensors, scanning probe tips etc. based on carbon nanotubes.
