Abstract
For analysis of biological samples, e.g. flagellar motor, we previously proposed the local environmental control system with nano/micro dual pipettes to change local ion/reagent concentration arbitrarily. However, in this system, the capability to control the local ion/reagent concentration was not sufficient. So, in this paper, to achieve more arbitrary local environmental control, we propose on-chip local environmental control system using micro fluidic chip with world-to-chip interface (WtCI) and micropipette. We develop the system and demonstrate the feasibility of the on-chip local environmental control system using micro fluidic chip with WtCI and micropipette.
