Comparison between selected magnetic nanoparticle manufacturing methods.

Manufacturing Method	Synthesis	Reaction Temp. (°C)	Reaction Time	Solvent	Surface-Capping Agents	Size Distribution	Shape Control	Yield
Coprecipitation	Very simple	20–90	Minutes	Water	During/after reaction	Relatively narrow	Not good	High
Microemulsion	Complicated	20–50	Hours	Organic agents	During reaction	Relatively narrow	Good	Low
Thermal decomposition	Complicated	100–320	Hours-days	Organic agents	During reaction	Very narrow	Very good	High
Hydrothermal	Simple	200–250	Hours-days	Water-ethanol	During reaction	Very narrow	Very good	Medium
Poliol	Simple	25-Boiling Point	Hours	Ethylene PEG	During reaction	Narrow	Very Good	High
