title: Electrodeposited Fe and Fe-Au nanowires as MRI contrast agents.
abstract: Electrodeposited Fe and Fe-Au nanowires were studied for potential as MRI contrast agents, especially for T2-weighted imaging. Transverse relaxivities up to r2= 77.1 mM Fe-1s-1(at 1.5 T) were achieved when Fe-Au nanowires were coated with thiol and carboxylic acid functionalized poly(ethyleneglycol). T2-Weighted images (9 T) verified successful contrast.
