rigid foamlike plugs in which resin beads are immobilized within an inert porous polyethylene matrix. The plugs "entrap a predetermined quantity of resin in such a way that it is free to react but is otherwise constrained inside the porous matrix. "They generally have significantly higher levels of functional group loading compared with equivalent-sized grafted or container devices." A future generation of StratoSpheres will have a broader range of shapes and dimensions and the capacity for encoding, he noted
