Microalgae, unicellular photosynthetic organisms, have received increasing attention for biological conversion of CO2 into valuable products. For the commercial use of microalgae, it is necessary to screen superior microalgal strains for enhanced biomass productivity. To isolate the fast-growing strains, we developed density–based separation of magnetic microdroplets encapsulating cells. In the application of magnetic field in the perpendicular direction of flow droplets, they could be attracted toward the magnet with different acceleration based on the density. Consequently, the 91.90% of empty, 87.12% of low, and 90.66% of high-density droplets could pass through the outlet 1, 2, and 3, respectively. These results demonstrated that microdroplets of different densities can be efficiently separated by magnetic force, suggesting the potential of microdroplet with magnetophoretic system as a platform for high-throughput screening of fast-growing strains. |
