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 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.
