Till-date research in communications industry has mainly focused on systems based on electromagnetic propagation. However, in nanotechnology the scales are very minute, hence it needs further research that whether these concepts apply or not. So far, molecular communications research has studied the propagation of individual molecules between closely spaced transmitters and receivers as embedded in a fluid medium. Using these concepts, scientists are now investigating into nanomachines, nanomedicines, nanorobotics, and bio-chips which have enabled to further the computer science communications with biologically inspired algorithms. If timely parallels can be drawn between molecular communications and electrical communications there is potential for cross-learning and an opportunity to pioneer new developments. This paper aims to bring forth the key principles in molecular communication and their relationship to electrical communications as out-of-the-box philosophy for academicians and students.
