Team Sendai Top



But on experiment, it is not smart that proceeing our project in order. Luckily, large number of people in our team(and most of us are fresh!). So we decided to separate our project into several part and do experiment parallelly. Our experiment separates three parts; Gate part, Porter part, and Membrane part.

Gate part is the group making the Cell-gate itself.

Porter part is the group making the function to transport the target in the channel.</br>

Membrane part is the group making liposome by using lipid.

To separate our project and finally mix, we aim to gain our achievement. And we also establish simmulation group that verifies each structure theoretically.

Projct GATE


GATE is the gatekeeper that allows only the target to enter the cell. Electric repulsions of the negative charge of DNA backbone inhibit NOT desired DNA from coming in the Gate.

Project PORTER


PORTER is the module for active transporter of the target in the GATE. The first Porter reaches the outside of the electric repulsion of the Gate, and pulls the target DNA inside the Gate by using hybridization energy. Inner Porters that have higher affinity than the first Porter push the target inside the Gate step by step.

As active transporters, the "CELL GATE" should work in membrane. Thus, a implementation module for inserting to membranes was designed. DNA with a hydrophobic molecule, cholesterol, hybridized around the GATE. We used liposome (artificial lipid vesicle) as a model cell membrane.

Application in future

Finally, this project aims to attach to real cell and transport a substance to cell and from cell. Of cause, this channel can be applied to medical use. Also, it can be used for bring some substance which it is difficult to bring back now from cell. In this experiment, we used liposome as a model of a cell membrane, but if we consider the channel attached liposome as one robot, the robot can use to cleaner robot or medical sprinkling robot.
