Molecular communication through gap junction channels: System design, experiments and modeling

Molecular communication is engineered biological communication that allows nanomachines to communicate through chemical signals. Nanomachines are small scale biological devices that either exist in nature or are artificially engineered from biological materials, and that perform simple functions such as sensing, processing, and actuation. As nanomachines are too small and simple to communicate through a traditional communication means (e.g. electromagnetic waves), molecular communication provides a mechanism for nanomachines to communicate by propagating molecules that represent information. In this paper, we propose to explore biological cells for engineering a molecular communication system. Its system characteristics and key networking services are first discussed, and then our current status of experimental and modeling studies is briefly reported.
