Abstract

Detecting magnetic nanoparticles with inductive sensor coils is a proven, feasible and cost-efficient method. Recently, molecular communication in fluids, primarily vascular system models, has been investigated. The one-sensor approach is useful for determining the presence of superparamagnetic iron-oxide nanoparticles (SPIONs) in the vicinity of the sensor. However, distinguishing between a small number of particles close to the sensor and a greater number further away remains problematic. To solve this, spatial detection using multiple sensors is investigated. This opens up the possibility of utilizing spatial information in a communication context, as well as enabling imaging options that display the particle distribution over the cross-sectional area of the channel. In consequence, the concentration can be determined with greater precision. The stability of the sensors is investigated, proving the reliability of reference scales for the shift to concentration relation. Nonetheless, the presented approach is subject to several limitations and factors that must be considered in future work. To conclude the presented work, it can be said that advances could be achieved in the position and concentration determination of SPIONs, as well as a structured investigation on sensor stability.
