The realization of interfaces between the biological world and elec- tronics has the potential to propel the field of Molecular Commu- nication (MC) to novel frontiers. Plugging MC-enabled devices to our electrical cyber-world will enable revolutionary applications, especially in the biomedical field. By stemming from a seminal proof-of-concept prototype that enables communication between a biological system and an electrical circuit, based on redox biochem- ical reactions, this paper introduces the first frequency analysis of such system and its characterization in terms of communication performance (capacity). To achieve these results, made possible by a linearity property in the analytical model of the system, an em- pirical methodology is followed to obtain the frequency response and the noise power spectral density of the system from the results of a simulation framework. The latter was developed in prior work and made accessible publicly through a web app. A water filling capacity estimation algorithm is applied to the obtained results to give a preliminary idea on the communication performance of such system, which results in a transmission rate equivalent to 0.0587 bits/hour. While orders of magnitude slower than common electrical or optical communications, these results are in line with the inherent timescales of the biological systems envisioned to be interfaced with this technology.
