The possibility to guide and control magnetic nanoparticles in a non-invasive manner has spawned various applications in biotechnology, such as targeted drug deliveryandsensingofbiologicalsubstances.Theseapplications are facilitated by the engineering of the size, selective chemical reactivity, and general chemical composition of the employed particles. Motivated by their widespread useandfavorableproperties,inthispaper,weprovideatheoreticalstudyofthepotentialbenefitsofmagneticnanoparticles for the design of molecular communication systems. In particular, we consider a magnetic nanoparticle-based communication in a microfluidic channel where an external magnetic field is employed to attract the informationcarrying particles to the receiver. We show that the particle transport affected by the Brownian motion, fluid flow, and an external magnetic field can be mathematically modeled as diffusion with drift. Thereby, we reveal that the key parameters determining the magnetic force are the particle size and the magnetic field gradient. Moreover, we derive an analyticalexpressionfor the channel impulse response, which is used to evaluatethe potentialgain in the expected number of observed nanoparticles due to the magnetic field.Furthermore,adoptingthesymbolerrorrateasperformance metric, we show that using magnetic nanoparticles can enable a reliable communication in the presence of disruptive fluid flow. The numerical results obtained by the particle-based simulation validate the accuracy of the derived analyticalexpressions.
