Fine-Tuning of Particle Size and Morphology of Silica Coated Iron Oxide Nanoparticles

Due to their unique properties such as superparamagnetism, easy surface functionalization, and colloidal stability among others, silica coated iron oxide nanoparticles (SIONPs) have received remarkable attention for biomedical applications in diagnostics or therapeutics. Tuning the particle size distribution of SIONPs a function solvent, catalyst, precursor, etc., modified Stöber’s method has been extensively studied. However, there no concerted effort study effect above parameters along with chemistry (IONPs) on morphologies obtained hence resultant magnetic properties. Here, we report an in-depth investigation nature concentration mass ratio IONPs precursor groups morphology SIONPs. We here first time evolution different morphologies, namely, fused, irregular, aggregate, spherical by careful control reaction conditions. Controlling sizes exerts influential and, thus, downstream.
