Dynamic nanodetectors for magnetic nanoparticles

Magnetic biosensors, in which disease markers in biological samples are tagged with magnetic nanoparticles, have the potential to be an important base technology for future point-of-care medical diagnostics devices. At the heart of many of these devices is a magnetoresistive sensor which detects the magnetic fields generated around the nanoparticles (and thus the presence of the disease marker). The aim of this project is to simulate novel, “dynamic” magnetic field sensing devices which have the potential to overcome some of the issues which affect traditional magnetoresistive sensors such as limited size scalability and response times. This is hoped to open routes to the development of a new class of magnetic biosensors.
