In the field of bio-engineering, there is a need for a specialized manipulator that protect targets from hard physical contact. The solution proposed in this paper is a system that controls micro flows to manipulate a micro-sized bio-target. The manipulation principle and system structure are presented. In addition, a simple model that uses physically observable parameters is constructed to capture the flow-target interactions following a chemically assisted flow visualization. The experimental results of a prototype are presented, and the feasibility is discussed. The purpose of this paper is to prove the feasibility of this manipulation method. Further developments are introduced, highlighting the full potential of the prototype.
