Manipulation and assembly of CuxS dendrites using optical tweezers

Abstract

We present the applications of optical tweezers to manipulate and assemble CuxS dendrites in fluidic medium. Our techniques involve the use of an optical tweezers, a single focused laser beam as non-contact manipulators to assemble CuxS at designated location in a sample chamber. Using this simple tool, we are able to readily arrange the dendrites into interesting configurations. Besides a simple focused laser beam, an asymmetrical line optical tweezers was utilized to manipulate and propel the CuxS along the length of the line tweezers. Finally, an application of using dendrites as a possible micro-machine powered by optical force has been explored in this work.
