The Development of a Biocompatible Testbed for Molecular Communication With Magnetic Nanoparticles
Max Bartunik, Georg Fischer, Jens Kirchner
Abstract
Although the concept of engineered molecular communication has been around for quite some time, practical approaches with truly biocompatible setups are still scarce. However, molecular communication has a large potential in future medical applications and may be a solution to size constraints of antenna-based transmission systems. In this work, we therefore present a testbed using biocompatible magnetic nanoparticles. Based on previous work, all testbed components have been improved regarding performance and size, making a large step forward regarding miniaturisation and a data transmission approach. In addition, a setup for localised two-dimensional sensing of magnetic nanoparticles is presented. All improvements are evaluated individually and combined to achieve a net data rate of more than <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\mathrm {6~ \text {bit} / \text {s}}$ </tex-math></inline-formula> , significantly higher than any other comparable biocompatible setup.
