LidMaterials with positive or neutral charge can pass through the gate freely regardless of electric potential of the Gate. Therefore, we considered the idea that we modified several long, but shorter than Porter1, single-stranded DNA at the entrance of Gate. All sequences were made of only adenine in order not to interact with Porter. It is expected that they prevent non-target materials from entering the Gate. Molecular dynamics simulation suggested such design is feasible. Under the simulation condition, a bead from outside do not have electricity. Lennard-Jones potential is the trigger of the repulsion to inhibit entrance of molecules.
