Neat. I did my Master's on a very similar idea. It was for performing several multi-step reactions in one reactor using some extra complexities, but the magnetic retrieval of the catalyst was the same. One issue with this that I see is that the covalent bonds created between the shell and core really need to be tested well in lots of pH and temperature environments, because if those NPs start degrading (which they always do at some level) then you're adding in contamination as well as removing it. That was always the scary part for me and why I've struggled to bring ideas to market - products that require precision don't really work in practice. The way things are used in the real world is very sloppy and products need quite enormous safety factors associated with them.
