The manipulation and assembly of CuO nanorods with line optical tweezers

Abstract

We present a simple technique for manipulating and assembling one-dimensional (1D) CuOnanorods. Our technique exploits the optical trapping ability of line optical tweezers totrap, manipulate and rotate nanorods without physical contact. With this simple andversatile method, nanorods can be readily arranged into interesting configurations. Theoptical line tweezers could also be used to manipulate an individual nanorodacross two conducting electrodes. This work demonstrates the potential of opticalmanipulation and assembly of 1D nanostructures into useful nanoelectronics devices.
