Claim: Iron–platinum nanoparticle may be synthesized by either usage of incident laser technology  or by coreduction of chloroplatinic acid and iron chloride in water-in-oil microemulsions.
Evidence: Currently there are many synthetic methods such as water-in-oil microemulsion, one-step thermal synthesis with metal precursors, and exchanged-coupled assembly for making FePt NPs. 
One method of synthesis uses incident laser technology to irradiate solutions containing iron and platinum to combine the two alloys. 
An alternative method of synthesis involves the coreduction of chloroplatinic acid (H2PtCl6) and iron (II) chloride in water-in-oil microemulsions.
