Spray-Dried Hierarchical Aggregates of Iron Oxide Nanoparticles and Their Functionalization for Downstream Processing in Biotechnology.
In this work, the structuring of iron oxide nanoparticles by way of spray-drying (SD) of aqueous suspensions is investigated, resulting in micrometer-sized aggregates with saturation magnetization corresponding to that of the person nanoparticles. Interestingly, the superparamagnetic conduct is retained regardless of the multicore construction. Modification of the aggregates by way of the addition of silica …
