Figure 3

Effects of three parameters (distance from the magnet, side position of the magnet, and magnetic nanoparticle concentration in microdroplets) on the magnetic force. (a) Measured magnetic flux density (mT) at a given distance from two different sides of the magnet. The rectangular magnet can have two different sides (position 1 and 2) showing different distribution of the magnetic field. The magnetic flux density at position 2 is higher than that at position 1 with distance range between 0 and 5,000 µm. (b) Microdroplets containing different concentrations of magnetic nanoparticles (2.5, 4.0, 4.96, 5.0 and 7.5 mg mL−1) are deflected toward different positions which can be determined by the distance from magnet. Data and error bars are mean ± SD (standard deviation) of three replicates.
