The importance of particle type selection and temperature control for on-chip free-flow magnetophoresis (2009)
Journal Article
Tarn, M. D., Peyman, S. A., Robert, D., Iles, A., Wilhelm, C., & Pamme, N. (2009). The importance of particle type selection and temperature control for on-chip free-flow magnetophoresis. Journal of Magnetism and Magnetic Materials, 321(24), 4115-4122. https://doi.org/10.1016/j.jmmm.2009.08.016

Free-flow magnetophoresis is becoming a popular technique for the separation and manipulation of magnetic particles and materials in microsystems. A wide variety of magnetic particles are commercially available that differ greatly in size and in magn...

Mobile magnetic particles as solid-supports for rapid surface-based bioanalysis in continuous flow (2009)
Journal Article
Peyman, S. A., Iles, A., & Pamme, N. (2009). Mobile magnetic particles as solid-supports for rapid surface-based bioanalysis in continuous flow. Lab on a chip, 9(21), 3110-3117. https://doi.org/10.1039/b904724g

An extremely versatile microfluidic device is demonstrated in which multi-step (bio) chemical procedures can be performed in continuous flow. The system operates by generating several co-laminar flow streams, which contain reagents for specific (bio)...

Diamagnetic repulsion—A versatile tool for label-free particle handling in microfluidic devices (2009)
Journal Article
Peyman, S. A., Kwan, E. Y., Margarson, O., Iles, A., & Pamme, N. (2009). Diamagnetic repulsion—A versatile tool for label-free particle handling in microfluidic devices. Journal of Chromatography A, 1216(52), 9055-9062. https://doi.org/10.1016/j.chroma.2009.06.039

We report the exploration of diamagnetic repulsion forces for the selective manipulation of microparticles inside microfluidic devices. Diamagnetic materials such as polymers are repelled from magnetic fields, an effect greatly enhanced by suspending...

On-chip diamagnetic repulsion in continuous flow (2009)
Journal Article
Tarn, M. D., Hirota, N., Iles, A., & Pamme, N. (2009). On-chip diamagnetic repulsion in continuous flow. Science and Technology of Advanced Materials, 10(1), 014611 - 014611. https://doi.org/10.1088/1468-6996/10/1/014611

We explore the potential of a microfluidic continuous flow particle separation system based on the repulsion of diamagnetic materials from a high magnetic field. Diamagnetic polystyrene particles in paramagnetic manganese (II) chloride solution were... Read More about On-chip diamagnetic repulsion in continuous flow.
