Abstract
Recently, toward the realization of micro/nano robots, the micro living organisms and the biomolecular motor have been used as the driving forces of the micro structures. To utilize these bio driving forces, firstly, it is needed to establish the methods to control the bio driving forces. In this paper, we try to control the delivery of the bacteria-driven micro structures by controlling the bacterial driving force with nano/micro pipette. We demonstrate the delivery control of the bacteria-driven 3 μm microbead by generating the local gradient of the attractant with 1 μm micropipette containing the attractant.
