Generation of swirl flow for non-contact rotation of micro objects by vibrating glass needle
In micromanipulation, a few of methods can be applied in the rotation of micro objects, which is very important for single cell injection, observation of micro objects and assembly of complex structures. In this paper, we present a novel method to realize the non-contact rotation of the micro objects by the swirl flow which is generated through vibrating glass needle in the fluid. Experiments of rotating micro bead have been carried out to demonstrate that the rotation is effective and efficient.
