New Publication: A new class of magnetically actuated pumps and valves for microfluidic applications - Centre for Metamaterial Research and Innovation (CMRI)

has published his latest article on “A new class of magnetically actuated pumps and valves for microfluidic applications” in Scientific Reports in Jan 2018. The research team proposes a new class of magnetically actuated pumps and valves that could be incorporated into microfluidic chips with no further external connections. The idea is to repurpose ferromagnetic low Reynolds number swimmers as devices capable of generating fluid flow, by restricting the swimmers’ translational degrees of freedom. Read more…

Fig: Flow in a Y-shaped channel. The swimmer is pinned at the centre of the junction and the bottom branch of the channel is aligned in parallel to the external magnetic field. The direction of the flow is shown with white arrows. (a) Flow direction in the presence of an applied magnetic field of strength 2.40 mT at a frequency of 60 Hz. (b) Flow direction in the presence of an applied magnetic field of strength 1.38 mT at a frequency of 130 Hz.
