Magnetobiology laboratory


Location: CRANN building 2.39

The Magnetobiology laboratory (Magnetism & Spintronic research group) located in the CRANN center 2.39 is purpose built and is dedicated to interdisciplinary research at the interface between the physical and life sciences and collaborates with the Nanobiophysics groups.

The research activities include investigation of cellular interactions using novel biophysical tools such as in vitro pulsed magnetic stimulation (TMS) of neuron networks and bio-magnetic detection using advanced magnetoresistive sensors for applications such as detecting magnetically-labeled biomarkers and magnetic flow cytometery.

Pulse magnetic stimulator platform for biological applications

Transcranial Magnetic Stimulation (TMS) of the nervous system has been an important tool in neuroscience for over twenty years. More recently many clinical applications have also been developed for diseases such as Multiple Sclerosis and Parkinson’s disease. The aims for this work is to elucidate the physical and biochemical mechanisms involved the in vitro magnetic stimulation of neuron and to measure TMS effects on neuronal development and neurotransmitter release.

TMS works via electromagnetic induction. Stimulation is achieved by inducing electrical currents in the tissue or cells via a magnetic field pulse as shown in the figure below.
