Controlled synthesis of SPION@SiO2nanoparticles using design of experiments

Abstract: The synthesis of single-core superparamagnetic iron oxide nanoparticles (SPIONs) coated with a silica shell of controlled thickness remains a challenge, due to the dependence on a multitude of experimental variables....

“…Although the top-down approach is suitable for large-scale production, they may not guarantee proper control over particle size and quality. , In contrast, chemical methods follow a bottom-up approach involving condensation of a material’s atoms or molecular entities in solution (i.e., wet chemical method: coprecipitation, sol–gel, microemulsion, hydrothermal, solvothermal, sonochemical, electrochemical, or thermal decomposition) or in gas phase (i.e., flame, laser, or plasma reactors). One of the most conventional techniques for SPION synthesis is coprecipitation of ferrous and ferric ion aqueous salt solutions with a base; however, its applicability is often limited by agglomeration, poor crystallinity, and polydispersity . Recent efforts to overcome these drawbacks include the use of ultrasound, preparation of magnetite nanoparticles under static magnetic field, and use of alkanolamines as base .…”

“…SPIONs are susceptible to oxidation, agglomeration, and lack of affinity for biomolecules without appropriate surface coating/modification. , Thus, it is important to understand the role of their surface coating on waste-activated sludge MW prehydrolysis applications. The reason for agglomeration is attributed to high surface area, van der Waals forces of attraction, and dipole–dipole interactions between the particles .…”
