Paper Abstract

Carbon nanocoils (CNCs) have attracted much attention due to their unique three-dimensional helix morphology, outstanding mechanical and electronic properties, and potential applications. Compared with carbon nanotubes, CNCs can be dispersed in solvents easily. In this paper, the manipulation of single CNCs by an optical tweezers has been demonstrated. It is found that these CNCs can be trapped, removed and rotated by the manipulation system, resulted from the asymmetrical distribution of optical trapping force generated on the CNCs with chiral features. Furthermore, the length of a single CNC can be adjusted by increasing the power of incident laser beam because the absorbed laser energy can be changed into thermal energy in a CNC. These results suggest that CNCs can be manipulated by an optical tweezers, which is suitable for the alignment of a CNC at a fixed position with a fixed length in electronic devices.
