Abstract: A membrane vesicle fission system is disclosed. The membrane vesicle fission system includes: a membrane vesicle having a lipid bi-layer membrane including a cationic lipid; and a unit which applies, to the membrane vesicle, an anionic material having a hydrophobic group.

Abstract: A disclosed molecular communication system includes a molecular transmitter configured to transmit an information molecule in which prescribed information is encoded, a molecular receiver configured to receive the information molecule, and a molecular capsule configured to carry the information molecule from the molecular transmitter to the molecular receiver. Each of the molecular transmitter, the molecular receiver, and the molecular capsule has an artificial cell membrane in which at least one kind of molecular switch is embedded, the molecular switch being responsive to an external input signal so as to control association and separation between the molecular transmitter and the molecular capsule, and association and separation between the molecular capsule and the molecular receiver, upon application of the external input signal.
