Abstract Silica-coated iron oxide nanoparticles are of enormous importance in biotechnology, nanomedicine, and catalysis. The study demonstrates the significant influence coating thickness on particle properties. Though slow magnetophoresis, a thinner shell leads to higher surface areas, lower isoelectric points, magnetizations. However, thick layers prevent oxidation lead stabilization. influenced binding cationic peptide lasioglossin, with maximal loading 0.23 g −1 for smallest particles....
