Abstract

This study describes numerical modelling of a magneto-biosensor detection coil using a Boundary Element Method (BEM). The Z and X axis magnetic profiles of the coil have been analysed. The model was extended to incorporate paramagnetic particles to evaluate coils Z and X axis detection sensitivity. We obtained a relationship between detection sensitivity and coil geometry specific flux density profile. A rule was derived to estimate the optimum distance of the sample from the coil and the size of the sample. It has been demonstrated that the simulation tool is a reliable method for fast, accurate modelling of a resonant coil biosensor detecting paramagnetic particles. Results from this study will be used to develop an optimised resonant coil magneto-biosensor.
