    dct:description "We synthesized PEGDA polymer hydrogel beads for cell embedding and compared REE biosorption with these beads via a gravity-driven flow through setup.  One way to set up a flow through system is by cell encapsulation into polymer beads with a column setup similar to that used in the chromatography industry.  To achieve this, we tested PEGDA for cell encapsulation, and tested REE biosorption under both batch mode and a follow through setup based on gravity .  For making the cell embedded polymer beads, we used a fluidic device by which homogenous spherical particles of 0.5 to1 mm in diameter were synthesized.   The beads are made relatively quickly, and the size of the beads can be controlled.  PEGDA beads were polymerized by UV.  Tb adsorption experiment was performed with beads with or without cells embedded.    " ;
