Molecular communication is a new and interdisciplinary research area that spans the nanotechnology, biotechnology, and communication technology. Molecular communication allows biological and artificially-created nanomachines to communicate over a short distance using molecules. In molecular communication, senders encode information onto information molecules and emit them. Information molecules are then loaded onto carrier molecules, propagate to receivers, and are unloaded from the carrier molecules. The receivers, upon receiving the information molecules, decode the information and react biochemically to the information molecules.
This abstract describes a design of a molecular communication interface using vesicles. In the design, the interface encapsulates the information molecules emitted from a sender in a small vesicle that is budded from a giant vesicle wrapping the sender. Then, the small vesicle is transported to a receiver. Once the small vesicle associates with a giant vesicle wrapping a receiver, it is absorbed into the giant vesicle and the information molecules are secreted into the giant vesicle and reach the receiver. The molecular communication interface using vesicles, therefore, can conceal different biochemical characteristics of transported information molecules against the molecular propagation system.
The authors are currently preparing for conducting biochemical experiments to investigate the feasibility of the molecular communication interface.
