Silane encapsulated magnetic iron oxide nanoparticles were synthesized through a sequential approach. The
nanoparticles were synthesised via a coprecipitation method to form Fe3O4 particles with an average particle size of 8.3 ±
2.3nm. Iron oxide nanoparticles were then coated with 3-glycidoxypropyltrimethoxysilane (GPTMS) to form core-shell
type particles. Coating was performed using a base catalysed sol-gel process involving the direct condensation of
GPTMS onto the particle surface. Elemental composition and crystal structure of the uncoated nanoparticles were
determined by XRD. The coated particles were characterised with infra-red spectroscopy and energy dispersive x-ray
spectroscopy (EDX) to confirm the presence of silane on the particles. TEM analysis and Scherrer broadening analysis of
XRD were used to determine particle size and morphology of both coated and uncoated particles.
