Abstract

We are exploring the use of magnetic attraction and diamagnetic repulsion forces for the handling of microparticles and cells in microchannels. Here, we report on the application of both of these types of forces to allow simultaneous trapping of magnetic and diamagnetic particles via a single set of magnets, and demonstrate the ability to perform assays on one type of particle while the other acts as a control. Additionally, we show how the setup can be adjusted to enable the continuous flow focusing of diamagnetic particles in a paramagnetic medium.
