Environmental oxidative aging of iron oxide nanoparticles
2018
Applied Physics Letters
Preserved Fulltext
The environmental aging of functional iron oxide nanomaterials, especially those used in biomedical applications, may have significant consequences for both their mechanism of action and their safety profile. However, to date, there has been no way to systematically measure this property, and the problem has been largely overlooked. We show here that a recently proposed "center of gravity" method for determining the composition of magnetite (Fe 3 O 4 ) and maghemite (c-Fe 2 O 3 ) mixtures via 57
