Abstract
We previously presented "organic nanotube (ONT) nanopipette". The spout of the fluorescent solution from ONT nanopipette was demonstrated by electro-osmotic phenomenon. For the local environmental control, it is needed to control the spouting volume and the spouting direction. In this paper, the electrostatic field is theoretically analyzed by finite element method to estimate the volume and the direction from ONT nanopipette. Based on the analytical results, the flow rate of electro-osmotic phenomenon was estimated at 0.75 fl/s in the ONT nanochannel. This result shows the possibility to control the local environment of inside of bacteria whose volume is several fl or more by the control of the spout in ms order.
